* cracking removed.

* the public domain as well, but I don't require that in order to let
* you place this code and any modifications you make under a license
* of your choice.
*
* This implementation is fully compatible with OpenBSD's bcrypt.c for prefix
* "$2b$", originally by Niels Provos <provos at citi.umich.edu>, and it uses
* some of his ideas. The password hashing algorithm was designed by David
* Mazieres <dm at lcs.mit.edu>. For information on the level of
* compatibility for bcrypt hash prefixes other than "$2b$", please refer to
* the comments in BF_set_key() below and to the included crypt(3) man page.
*
* There's a paper on the algorithm that explains its design decisions:
*
* http://www.usenix.org/events/usenix99/provos.html
*
* Some of the tricks in BF_ROUND might be inspired by Eric Young's
* Blowfish library (I can't be sure if I would think of something if I
* hadn't seen his code).

* There was a sign extension bug in older revisions of this function. While
* we would have liked to simply fix the bug and move on, we have to provide
* a backwards compatibility feature (essentially the bug) for some systems and
* a safety measure for some others. The latter is needed because for certain
* multiple inputs to the buggy algorithm there exist easily found inputs to
* the correct algorithm that produce the same hash. Thus, we optionally
* deviate from the correct algorithm just enough to avoid such collisions.
* While the bug itself affected the majority of passwords containing
* characters with the 8th bit set (although only a percentage of those in a
* collision-producing way), the anti-collision safety measure affects
* only a subset of passwords containing the '\xff' character (not even all of
* those passwords, just some of them). This character is not found in valid
* UTF-8 sequences and is rarely used in popular 8-bit character encodings.
* Thus, the safety measure is unlikely to cause much annoyance, and is a
* reasonable tradeoff to use when authenticating against existing hashes that
* are not reliably known to have been computed with the correct algorithm.
*
* We use an approach that tries to minimize side-channel leaks of password
* information - that is, we mostly use fixed-cost bitwise operations instead
* of branches or table lookups. (One conditional branch based on password
* length remains. It is not part of the bug aftermath, though, and is
* difficult and possibly unreasonable to avoid given the use of C strings by
* the caller, which results in similar timing leaks anyway.)
*
* For actual implementation, we set an array index in the variable "bug"
* (0 means no bug, 1 means sign extension bug emulation) and a flag in the
* variable "safety" (bit 16 is set when the safety measure is requested).
* Valid combinations of settings are:
*
* Prefix "$2a$": bug = 0, safety = 0x10000
* Prefix "$2b$": bug = 0, safety = 0
* Prefix "$2x$": bug = 1, safety = 0

/*
* This version has been further modified by Rich Felker, primary author
* and maintainer of musl libc, to remove table generation code and
* replaced all runtime-generated constant tables with static-initialized
* tables in the binary, in the interest of minimizing non-shareable
* memory usage and stack size requirements.
*/
/*
* This version is derived from the original implementation of FreeSec
* (release 1.1) by David Burren. I've made it reentrant, reduced its memory
* usage from about 70 KB to about 7 KB (with only minimal performance impact
* and keeping code size about the same), made the handling of invalid salts
* mostly UFC-crypt compatible, added a quick runtime self-test (which also
* serves to zeroize the stack from sensitive data), and added optional tests.

cosmopolitan/third_party/unzip/zipinfo.txt | ZIPINFO(1L) ZIPINFO(1L)
NAME
zipinfo - list detailed information about a ZIP archive
SYNOPSIS
zipinfo [-12smlvhMtTz] file[.zip] [file(s) ...] [-x xfile(s) ...]
unzip -Z [-12smlvhMtTz] file[.zip] [file(s) ...] [-x xfile(s) ...]
DESCRIPTION
zipinfo lists technical information about files in a ZIP archive, most
commonly found on MS-DOS systems. Such information includes file
access permissions, encryption status, type of compression, version and
operating system or file system of compressing program, and the like.
The default behavior (with no options) is to list single-line entries
for each file in the archive, with header and trailer lines providing
summary information for the entire archive. The format is a cross
between Unix ``ls -l'' and ``unzip -v'' output. See DETAILED DESCRIP-
TION below. Note that zipinfo is the same program as unzip (under
Unix, a link to it); on some systems, however, zipinfo support may have
been omitted when unzip was compiled.
ARGUMENTS
file[.zip]
Path of the ZIP archive(s). If the file specification is a
wildcard, each matching file is processed in an order determined
by the operating system (or file system). Only the filename can
be a wildcard; the path itself cannot. Wildcard expressions are
similar to Unix egrep(1) (regular) expressions and may contain:
* matches a sequence of 0 or more characters
? matches exactly 1 character
[...] matches any single character found inside the brackets;
ranges are specified by a beginning character, a hyphen,
and an ending character. If an exclamation point or a
caret (`!' or `^') follows the left bracket, then the
range of characters within the brackets is complemented
(that is, anything except the characters inside the
brackets is considered a match). To specify a verbatim
left bracket, the three-character sequence ``[[]'' has to
be used.
(Be sure to quote any character that might otherwise be inter-
preted or modified by the operating system, particularly under
Unix and VMS.) If no matches are found, the specification is
assumed to be a literal filename; and if that also fails, the
suffix .zip is appended. Note that self-extracting ZIP files
are supported, as with any other ZIP archive; just specify the
.exe suffix (if any) explicitly.
[file(s)]
An optional list of archive members to be processed, separated
by spaces. (VMS versions compiled with VMSCLI defined must
delimit files with commas instead.) Regular expressions (wild-
cards) may be used to match multiple members; see above. Again,
be sure to quote expressions that would otherwise be expanded or
modified by the operating system.
[-x xfile(s)]
An optional list of archive members to be excluded from process-
ing.
OPTIONS
-1 list filenames only, one per line. This option excludes all
others; headers, trailers and zipfile comments are never
printed. It is intended for use in Unix shell scripts.
-2 list filenames only, one per line, but allow headers (-h),
trailers (-t) and zipfile comments (-z), as well. This option
may be useful in cases where the stored filenames are particu-
larly long.
-s list zipfile info in short Unix ``ls -l'' format. This is the
default behavior; see below.
-m list zipfile info in medium Unix ``ls -l'' format. Identical to
the -s output, except that the compression factor, expressed as
a percentage, is also listed.
-l list zipfile info in long Unix ``ls -l'' format. As with -m
except that the compressed size (in bytes) is printed instead of
the compression ratio.
-v list zipfile information in verbose, multi-page format.
-h list header line. The archive name, actual size (in bytes) and
total number of files is printed.
-M pipe all output through an internal pager similar to the Unix
more(1) command. At the end of a screenful of output, zipinfo
pauses with a ``--More--'' prompt; the next screenful may be
viewed by pressing the Enter (Return) key or the space bar.
zipinfo can be terminated by pressing the ``q'' key and, on some
systems, the Enter/Return key. Unlike Unix more(1), there is no
forward-searching or editing capability. Also, zipinfo doesn't
notice if long lines wrap at the edge of the screen, effectively
resulting in the printing of two or more lines and the likeli-
hood that some text will scroll off the top of the screen before
being viewed. On some systems the number of available lines on
the screen is not detected, in which case zipinfo assumes the
height is 24 lines.
-t list totals for files listed or for all files. The number of
files listed, their uncompressed and compressed total sizes ,
and their overall compression factor is printed; or, if only the
totals line is being printed, the values for the entire archive
are given. The compressed total size does not include the 12
additional header bytes of each encrypted entry. Note that the
total compressed (data) size will never match the actual zipfile
size, since the latter includes all of the internal zipfile
headers in addition to the compressed data.
-T print the file dates and times in a sortable decimal format
(yymmdd.hhmmss). The default date format is a more standard,
human-readable version with abbreviated month names (see exam-
ples below).
-U [UNICODE_SUPPORT only] modify or disable UTF-8 handling. When
UNICODE_SUPPORT is available, the option -U forces unzip to
escape all non-ASCII characters from UTF-8 coded filenames as
``#Uxxxx''. This option is mainly provided for debugging pur-
pose when the fairly new UTF-8 support is suspected to mangle up
extracted filenames.
The option -UU allows to entirely disable the recognition of
UTF-8 encoded filenames. The handling of filename codings
within unzip falls back to the behaviour of previous versions.
-z include the archive comment (if any) in the listing.
DETAILED DESCRIPTION
zipinfo has a number of modes, and its behavior can be rather difficult
to fathom if one isn't familiar with Unix ls(1) (or even if one is).
The default behavior is to list files in the following format:
-rw-rws--- 1.9 unx 2802 t- defX 11-Aug-91 13:48 perms.2660
The last three fields are the modification date and time of the file,
and its name. The case of the filename is respected; thus files that
come from MS-DOS PKZIP are always capitalized. If the file was zipped
with a stored directory name, that is also displayed as part of the
filename.
The second and third fields indicate that the file was zipped under
Unix with version 1.9 of zip. Since it comes from Unix, the file per-
missions at the beginning of the line are printed in Unix format. The
uncompressed file-size (2802 in this example) is the fourth field.
The fifth field consists of two characters, either of which may take on
several values. The first character may be either `t' or `b', indicat-
ing that zip believes the file to be text or binary, respectively; but
if the file is encrypted, zipinfo notes this fact by capitalizing the
character (`T' or `B'). The second character may also take on four
values, depending on whether there is an extended local header and/or
an ``extra field'' associated with the file (fully explained in
PKWare's APPNOTE.TXT, but basically analogous to pragmas in ANSI
C--i.e., they provide a standard way to include non-standard informa-
tion in the archive). If neither exists, the character will be a
hyphen (`-'); if there is an extended local header but no extra field,
`l'; if the reverse, `x'; and if both exist, `X'. Thus the file in
this example is (probably) a text file, is not encrypted, and has nei-
ther an extra field nor an extended local header associated with it.
The example below, on the other hand, is an encrypted binary file with
an extra field:
RWD,R,R 0.9 vms 168 Bx shrk 9-Aug-91 19:15 perms.0644
Extra fields are used for various purposes (see discussion of the -v
option below) including the storage of VMS file attributes, which is
presumably the case here. Note that the file attributes are listed in
VMS format. Some other possibilities for the host operating system
(which is actually a misnomer--host file system is more correct)
include OS/2 or NT with High Performance File System (HPFS), MS-DOS,
OS/2 or NT with File Allocation Table (FAT) file system, and Macintosh.
These are denoted as follows:
-rw-a-- 1.0 hpf 5358 Tl i4:3 4-Dec-91 11:33 longfilename.hpfs
-r--ahs 1.1 fat 4096 b- i4:2 14-Jul-91 12:58 EA DATA. SF
--w------- 1.0 mac 17357 bx i8:2 4-May-92 04:02 unzip.macr
File attributes in the first two cases are indicated in a Unix-like
format, where the seven subfields indicate whether the file: (1) is a
directory, (2) is readable (always true), (3) is writable, (4) is exe-
cutable (guessed on the basis of the extension--.exe, .com, .bat, .cmd
and .btm files are assumed to be so), (5) has its archive bit set, (6)
is hidden, and (7) is a system file. Interpretation of Macintosh file
attributes is unreliable because some Macintosh archivers don't store
any attributes in the archive.
Finally, the sixth field indicates the compression method and possible
sub-method used. There are six methods known at present: storing (no
compression), reducing, shrinking, imploding, tokenizing (never pub-
licly released), and deflating. In addition, there are four levels of
reducing (1 through 4); four types of imploding (4K or 8K sliding dic-
tionary, and 2 or 3 Shannon-Fano trees); and four levels of deflating
(superfast, fast, normal, maximum compression). zipinfo represents
these methods and their sub-methods as follows: stor; re:1, re:2,
etc.; shrk; i4:2, i8:3, etc.; tokn; and defS, defF, defN, and defX.
The medium and long listings are almost identical to the short format
except that they add information on the file's compression. The medium
format lists the file's compression factor as a percentage indicating
the amount of space that has been ``removed'':
-rw-rws--- 1.5 unx 2802 t- 81% defX 11-Aug-91 13:48 perms.2660
In this example, the file has been compressed by more than a factor of
five; the compressed data are only 19% of the original size. The long
format gives the compressed file's size in bytes, instead:
-rw-rws--- 1.5 unx 2802 t- 538 defX 11-Aug-91 13:48 perms.2660
In contrast to the unzip listings, the compressed size figures in this
listing format denote the complete size of compressed data, including
the 12 extra header bytes in case of encrypted entries.
Adding the -T option changes the file date and time to decimal format:
-rw-rws--- 1.5 unx 2802 t- 538 defX 910811.134804 perms.2660
Note that because of limitations in the MS-DOS format used to store
file times, the seconds field is always rounded to the nearest even
second. For Unix files this is expected to change in the next major
releases of zip(1L) and unzip.
In addition to individual file information, a default zipfile listing
also includes header and trailer lines:
Archive: OS2.zip 5453 bytes 5 files
,,rw, 1.0 hpf 730 b- i4:3 26-Jun-92 23:40 Contents
,,rw, 1.0 hpf 3710 b- i4:3 26-Jun-92 23:33 makefile.os2
,,rw, 1.0 hpf 8753 b- i8:3 26-Jun-92 15:29 os2unzip.c
,,rw, 1.0 hpf 98 b- stor 21-Aug-91 15:34 unzip.def
,,rw, 1.0 hpf 95 b- stor 21-Aug-91 17:51 zipinfo.def
5 files, 13386 bytes uncompressed, 4951 bytes compressed: 63.0%
The header line gives the name of the archive, its total size, and the
total number of files; the trailer gives the number of files listed,
their total uncompressed size, and their total compressed size (not
including any of zip's internal overhead). If, however, one or more
file(s) are provided, the header and trailer lines are not listed.
This behavior is also similar to that of Unix's ``ls -l''; it may be
overridden by specifying the -h and -t options explicitly. In such a
case the listing format must also be specified explicitly, since -h or
-t (or both) in the absence of other options implies that ONLY the
header or trailer line (or both) is listed. See the EXAMPLES section
below for a semi-intelligible translation of this nonsense.
The verbose listing is mostly self-explanatory. It also lists file
comments and the zipfile comment, if any, and the type and number of
bytes in any stored extra fields. Currently known types of extra
fields include PKWARE's authentication (``AV'') info; OS/2 extended
attributes; VMS filesystem info, both PKWARE and Info-ZIP versions;
Macintosh resource forks; Acorn/Archimedes SparkFS info; and so on.
(Note that in the case of OS/2 extended attributes--perhaps the most
common use of zipfile extra fields--the size of the stored EAs as
reported by zipinfo may not match the number given by OS/2's dir com-
mand: OS/2 always reports the number of bytes required in 16-bit for-
mat, whereas zipinfo always reports the 32-bit storage.)
Again, the compressed size figures of the individual entries include
the 12 extra header bytes for encrypted entries. In contrast, the
archive total compressed size and the average compression ratio shown
in the summary bottom line are calculated without the extra 12 header
bytes of encrypted entries.
ENVIRONMENT OPTIONS
Modifying zipinfo's default behavior via options placed in an environ-
ment variable can be a bit complicated to explain, due to zipinfo's
attempts to handle various defaults in an intuitive, yet Unix-like,
manner. (Try not to laugh.) Nevertheless, there is some underlying
logic. In brief, there are three ``priority levels'' of options: the
default options; environment options, which can override or add to the
defaults; and explicit options given by the user, which can override or
add to either of the above.
The default listing format, as noted above, corresponds roughly to the
"zipinfo -hst" command (except when individual zipfile members are
specified). A user who prefers the long-listing format (-l) can make
use of the zipinfo's environment variable to change this default:
Unix Bourne shell:
ZIPINFO=-l; export ZIPINFO
Unix C shell:
setenv ZIPINFO -l
OS/2 or MS-DOS:
set ZIPINFO=-l
VMS (quotes for lowercase):
define ZIPINFO_OPTS "-l"
If, in addition, the user dislikes the trailer line, zipinfo's concept
of ``negative options'' may be used to override the default inclusion
of the line. This is accomplished by preceding the undesired option
with one or more minuses: e.g., ``-l-t'' or ``--tl'', in this example.
The first hyphen is the regular switch character, but the one before
the `t' is a minus sign. The dual use of hyphens may seem a little
awkward, but it's reasonably intuitive nonetheless: simply ignore the
first hyphen and go from there. It is also consistent with the behav-
ior of the Unix command nice(1).
As suggested above, the default variable names are ZIPINFO_OPTS for VMS
(where the symbol used to install zipinfo as a foreign command would
otherwise be confused with the environment variable), and ZIPINFO for
all other operating systems. For compatibility with zip(1L), ZIPIN-
FOOPT is also accepted (don't ask). If both ZIPINFO and ZIPINFOOPT are
defined, however, ZIPINFO takes precedence. unzip's diagnostic option
(-v with no zipfile name) can be used to check the values of all four
possible unzip and zipinfo environment variables.
EXAMPLES
To get a basic, short-format listing of the complete contents of a ZIP
archive storage.zip, with both header and totals lines, use only the
archive name as an argument to zipinfo:
zipinfo storage
To produce a basic, long-format listing (not verbose), including header
and totals lines, use -l:
zipinfo -l storage
To list the complete contents of the archive without header and totals
lines, either negate the -h and -t options or else specify the contents
explicitly:
zipinfo --h-t storage
zipinfo storage \*
(where the backslash is required only if the shell would otherwise
expand the `*' wildcard, as in Unix when globbing is turned on--double
quotes around the asterisk would have worked as well). To turn off the
totals line by default, use the environment variable (C shell is
assumed here):
setenv ZIPINFO --t
zipinfo storage
To get the full, short-format listing of the first example again, given
that the environment variable is set as in the previous example, it is
necessary to specify the -s option explicitly, since the -t option by
itself implies that ONLY the footer line is to be printed:
setenv ZIPINFO --t
zipinfo -t storage [only totals line]
zipinfo -st storage [full listing]
The -s option, like -m and -l, includes headers and footers by default,
unless otherwise specified. Since the environment variable specified
no footers and that has a higher precedence than the default behavior
of -s, an explicit -t option was necessary to produce the full listing.
Nothing was indicated about the header, however, so the -s option was
sufficient. Note that both the -h and -t options, when used by them-
selves or with each other, override any default listing of member
files; only the header and/or footer are printed. This behavior is
useful when zipinfo is used with a wildcard zipfile specification; the
contents of all zipfiles are then summarized with a single command.
To list information on a single file within the archive, in medium for-
mat, specify the filename explicitly:
zipinfo -m storage unshrink.c
The specification of any member file, as in this example, will override
the default header and totals lines; only the single line of informa-
tion about the requested file will be printed. This is intuitively
what one would expect when requesting information about a single file.
For multiple files, it is often useful to know the total compressed and
uncompressed size; in such cases -t may be specified explicitly:
zipinfo -mt storage "*.[ch]" Mak\*
To get maximal information about the ZIP archive, use the verbose
option. It is usually wise to pipe the output into a filter such as
Unix more(1) if the operating system allows it:
zipinfo -v storage | more
Finally, to see the most recently modified files in the archive, use
the -T option in conjunction with an external sorting utility such as
Unix sort(1) (and sed(1) as well, in this example):
zipinfo -T storage | sort -nr -k 7 | sed 15q
The -nr option to sort(1) tells it to sort numerically in reverse order
rather than in textual order, and the -k 7 option tells it to sort on
the seventh field. This assumes the default short-listing format; if
-m or -l is used, the proper sort(1) option would be -k 8. Older ver-
sions of sort(1) do not support the -k option, but you can use the
traditional + option instead, e.g., +6 instead of -k 7. The sed(1)
command filters out all but the first 15 lines of the listing. Future
releases of zipinfo may incorporate date/time and filename sorting as
built-in options.
TIPS
The author finds it convenient to define an alias ii for zipinfo on
systems that allow aliases (or, on other systems, copy/rename the exe-
cutable, create a link or create a command file with the name ii). The
ii usage parallels the common ll alias for long listings in Unix, and
the similarity between the outputs of the two commands was intentional.
BUGS
As with unzip, zipinfo's -M (``more'') option is overly simplistic in
its handling of screen output; as noted above, it fails to detect the
wrapping of long lines and may thereby cause lines at the top of the
screen to be scrolled off before being read. zipinfo should detect and
treat each occurrence of line-wrap as one additional line printed.
This requires knowledge of the screen's width as well as its height.
In addition, zipinfo should detect the true screen geometry on all sys-
tems.
zipinfo's listing-format behavior is unnecessarily complex and should
be simplified. (This is not to say that it will be.)

NAME
unzip - list, test and extract compressed files in a ZIP archive
SYNOPSIS
unzip [-Z] [-cflptTuvz[abjnoqsCDKLMUVWX$/:^]] file[.zip] [file(s) ...]
[-x xfile(s) ...] [-d exdir]
DESCRIPTION
unzip will list, test, or extract files from a ZIP archive, commonly
found on MS-DOS systems. The default behavior (with no options) is to
extract into the current directory (and subdirectories below it) all
files from the specified ZIP archive. A companion program, zip(1L),
creates ZIP archives; both programs are compatible with archives cre-
ated by PKWARE's PKZIP and PKUNZIP for MS-DOS, but in many cases the
program options or default behaviors differ.
ARGUMENTS
file[.zip]
Path of the ZIP archive(s). If the file specification is a
wildcard, each matching file is processed in an order determined
by the operating system (or file system). Only the filename can
be a wildcard; the path itself cannot. Wildcard expressions are
similar to those supported in commonly used Unix shells (sh,
ksh, csh) and may contain:
* matches a sequence of 0 or more characters
? matches exactly 1 character
[...] matches any single character found inside the brackets;
ranges are specified by a beginning character, a hyphen,
and an ending character. If an exclamation point or a
caret (`!' or `^') follows the left bracket, then the
range of characters within the brackets is complemented
(that is, anything except the characters inside the
brackets is considered a match). To specify a verbatim
left bracket, the three-character sequence ``[[]'' has to
be used.
(Be sure to quote any character that might otherwise be inter-
preted or modified by the operating system, particularly under
Unix and VMS.) If no matches are found, the specification is
assumed to be a literal filename; and if that also fails, the
suffix .zip is appended. Note that self-extracting ZIP files
are supported, as with any other ZIP archive; just specify the
.exe suffix (if any) explicitly.
[file(s)]
An optional list of archive members to be processed, separated
by spaces. (VMS versions compiled with VMSCLI defined must
delimit files with commas instead. See -v in OPTIONS below.)
Regular expressions (wildcards) may be used to match multiple
members; see above. Again, be sure to quote expressions that
would otherwise be expanded or modified by the operating system.
[-x xfile(s)]
An optional list of archive members to be excluded from process-
ing. Since wildcard characters normally match (`/') directory
separators (for exceptions see the option -W), this option may
be used to exclude any files that are in subdirectories. For
example, ``unzip foo *.[ch] -x */*'' would extract all C source
files in the main directory, but none in any subdirectories.
Without the -x option, all C source files in all directories
within the zipfile would be extracted.
[-d exdir]
An optional directory to which to extract files. By default,
all files and subdirectories are recreated in the current direc-
tory; the -d option allows extraction in an arbitrary directory
(always assuming one has permission to write to the directory).
This option need not appear at the end of the command line; it
is also accepted before the zipfile specification (with the nor-
mal options), immediately after the zipfile specification, or
between the file(s) and the -x option. The option and directory
may be concatenated without any white space between them, but
note that this may cause normal shell behavior to be suppressed.
In particular, ``-d ~'' (tilde) is expanded by Unix C shells
into the name of the user's home directory, but ``-d~'' is
treated as a literal subdirectory ``~'' of the current direc-
tory.
OPTIONS
Note that, in order to support obsolescent hardware, unzip's usage
screen is limited to 22 or 23 lines and should therefore be considered
only a reminder of the basic unzip syntax rather than an exhaustive
list of all possible flags. The exhaustive list follows:
-Z zipinfo(1L) mode. If the first option on the command line is
-Z, the remaining options are taken to be zipinfo(1L) options.
See the appropriate manual page for a description of these
options.
-A [OS/2, Unix DLL] print extended help for the DLL's programming
interface (API).
-c extract files to stdout/screen (``CRT''). This option is simi-
lar to the -p option except that the name of each file is
printed as it is extracted, the -a option is allowed, and ASCII-
EBCDIC conversion is automatically performed if appropriate.
This option is not listed in the unzip usage screen.
-f freshen existing files, i.e., extract only those files that
already exist on disk and that are newer than the disk copies.
By default unzip queries before overwriting, but the -o option
may be used to suppress the queries. Note that under many oper-
ating systems, the TZ (timezone) environment variable must be
set correctly in order for -f and -u to work properly (under
Unix the variable is usually set automatically). The reasons
for this are somewhat subtle but have to do with the differences
between DOS-format file times (always local time) and Unix-for-
mat times (always in GMT/UTC) and the necessity to compare the
two. A typical TZ value is ``PST8PDT'' (US Pacific time with
automatic adjustment for Daylight Savings Time or ``summer
time'').
-l list archive files (short format). The names, uncompressed file
sizes and modification dates and times of the specified files
are printed, along with totals for all files specified. If
UnZip was compiled with OS2_EAS defined, the -l option also
lists columns for the sizes of stored OS/2 extended attributes
(EAs) and OS/2 access control lists (ACLs). In addition, the
zipfile comment and individual file comments (if any) are dis-
played. If a file was archived from a single-case file system
(for example, the old MS-DOS FAT file system) and the -L option
was given, the filename is converted to lowercase and is pre-
fixed with a caret (^).
-p extract files to pipe (stdout). Nothing but the file data is
sent to stdout, and the files are always extracted in binary
format, just as they are stored (no conversions).
-t test archive files. This option extracts each specified file in
memory and compares the CRC (cyclic redundancy check, an
enhanced checksum) of the expanded file with the original file's
stored CRC value.
-T [most OSes] set the timestamp on the archive(s) to that of the
newest file in each one. This corresponds to zip's -go option
except that it can be used on wildcard zipfiles (e.g., ``unzip
-T \*.zip'') and is much faster.
-u update existing files and create new ones if needed. This
option performs the same function as the -f option, extracting
(with query) files that are newer than those with the same name
on disk, and in addition it extracts those files that do not
already exist on disk. See -f above for information on setting
the timezone properly.
-v list archive files (verbose format) or show diagnostic version
info. This option has evolved and now behaves as both an option
and a modifier. As an option it has two purposes: when a zip-
file is specified with no other options, -v lists archive files
verbosely, adding to the basic -l info the compression method,
compressed size, compression ratio and 32-bit CRC. In contrast
to most of the competing utilities, unzip removes the 12 addi-
tional header bytes of encrypted entries from the compressed
size numbers. Therefore, compressed size and compression ratio
figures are independent of the entry's encryption status and
show the correct compression performance. (The complete size of
the encrypted compressed data stream for zipfile entries is
reported by the more verbose zipinfo(1L) reports, see the sepa-
rate manual.) When no zipfile is specified (that is, the com-
plete command is simply ``unzip -v''), a diagnostic screen is
printed. In addition to the normal header with release date and
version, unzip lists the home Info-ZIP ftp site and where to
find a list of other ftp and non-ftp sites; the target operating
system for which it was compiled, as well as (possibly) the
hardware on which it was compiled, the compiler and version
used, and the compilation date; any special compilation options
that might affect the program's operation (see also DECRYPTION
below); and any options stored in environment variables that
might do the same (see ENVIRONMENT OPTIONS below). As a modi-
fier it works in conjunction with other options (e.g., -t) to
produce more verbose or debugging output; this is not yet fully
implemented but will be in future releases.
-z display only the archive comment.
MODIFIERS
-a convert text files. Ordinarily all files are extracted exactly
as they are stored (as ``binary'' files). The -a option causes
files identified by zip as text files (those with the `t' label
in zipinfo listings, rather than `b') to be automatically
extracted as such, converting line endings, end-of-file charac-
ters and the character set itself as necessary. (For example,
Unix files use line feeds (LFs) for end-of-line (EOL) and have
no end-of-file (EOF) marker; Macintoshes use carriage returns
(CRs) for EOLs; and most PC operating systems use CR+LF for EOLs
and control-Z for EOF. In addition, IBM mainframes and the
Michigan Terminal System use EBCDIC rather than the more common
ASCII character set, and NT supports Unicode.) Note that zip's
identification of text files is by no means perfect; some
``text'' files may actually be binary and vice versa. unzip
therefore prints ``[text]'' or ``[binary]'' as a visual check
for each file it extracts when using the -a option. The -aa
option forces all files to be extracted as text, regardless of
the supposed file type. On VMS, see also -S.
-b [general] treat all files as binary (no text conversions). This
is a shortcut for ---a.
-b [Tandem] force the creation files with filecode type 180 ('C')
when extracting Zip entries marked as "text". (On Tandem, -a is
enabled by default, see above).
-b [VMS] auto-convert binary files (see -a above) to fixed-length,
512-byte record format. Doubling the option (-bb) forces all
files to be extracted in this format. When extracting to stan-
dard output (-c or -p option in effect), the default conversion
of text record delimiters is disabled for binary (-b) resp. all
(-bb) files.
-B [when compiled with UNIXBACKUP defined] save a backup copy of
each overwritten file. The backup file is gets the name of the
target file with a tilde and optionally a unique sequence number
(up to 5 digits) appended. The sequence number is applied when-
ever another file with the original name plus tilde already
exists. When used together with the "overwrite all" option -o,
numbered backup files are never created. In this case, all
backup files are named as the original file with an appended
tilde, existing backup files are deleted without notice. This
feature works similarly to the default behavior of emacs(1) in
many locations.
Example: the old copy of ``foo'' is renamed to ``foo~''.
Warning: Users should be aware that the -B option does not pre-
vent loss of existing data under all circumstances. For exam-
ple, when unzip is run in overwrite-all mode, an existing
``foo~'' file is deleted before unzip attempts to rename ``foo''
to ``foo~''. When this rename attempt fails (because of a file
locks, insufficient privileges, or ...), the extraction of
``foo~'' gets cancelled, but the old backup file is already
lost. A similar scenario takes place when the sequence number
range for numbered backup files gets exhausted (99999, or 65535
for 16-bit systems). In this case, the backup file with the
maximum sequence number is deleted and replaced by the new

-C use case-insensitive matching for the selection of archive
entries from the command-line list of extract selection pat-
terns. unzip's philosophy is ``you get what you ask for'' (this
is also responsible for the -L/-U change; see the relevant
options below). Because some file systems are fully case-sensi-
tive (notably those under the Unix operating system) and because
both ZIP archives and unzip itself are portable across plat-
forms, unzip's default behavior is to match both wildcard and
literal filenames case-sensitively. That is, specifying ``make-
file'' on the command line will only match ``makefile'' in the
archive, not ``Makefile'' or ``MAKEFILE'' (and similarly for
wildcard specifications). Since this does not correspond to the
behavior of many other operating/file systems (for example, OS/2
HPFS, which preserves mixed case but is not sensitive to it),
the -C option may be used to force all filename matches to be
case-insensitive. In the example above, all three files would
then match ``makefile'' (or ``make*'', or similar). The -C
option affects file specs in both the normal file list and the
excluded-file list (xlist).
Please note that the -C option does neither affect the search
for the zipfile(s) nor the matching of archive entries to exist-
ing files on the extraction path. On a case-sensitive file sys-
tem, unzip will never try to overwrite a file ``FOO'' when
extracting an entry ``foo''!
-D skip restoration of timestamps for extracted items. Normally,
unzip tries to restore all meta-information for extracted items
that are supplied in the Zip archive (and do not require privi-
leges or impose a security risk). By specifying -D, unzip is
told to suppress restoration of timestamps for directories
explicitly created from Zip archive entries. This option only
applies to ports that support setting timestamps for directories
(currently ATheOS, BeOS, MacOS, OS/2, Unix, VMS, Win32, for
other unzip ports, -D has no effect). The duplicated option -DD
forces suppression of timestamp restoration for all extracted
entries (files and directories). This option results in setting
the timestamps for all extracted entries to the current time.
On VMS, the default setting for this option is -D for consis-
tency with the behaviour of BACKUP: file timestamps are
restored, timestamps of extracted directories are left at the
current time. To enable restoration of directory timestamps,
the negated option --D should be specified. On VMS, the option
-D disables timestamp restoration for all extracted Zip archive
items. (Here, a single -D on the command line combines with the
default -D to do what an explicit -DD does on other systems.)
-E [MacOS only] display contents of MacOS extra field during
restore operation.
-F [Acorn only] suppress removal of NFS filetype extension from
stored filenames.
-F [non-Acorn systems supporting long filenames with embedded com-
mas, and only if compiled with ACORN_FTYPE_NFS defined] trans-
late filetype information from ACORN RISC OS extra field blocks
into a NFS filetype extension and append it to the names of the
extracted files. (When the stored filename appears to already
have an appended NFS filetype extension, it is replaced by the
info from the extra field.)
-i [MacOS only] ignore filenames stored in MacOS extra fields.
Instead, the most compatible filename stored in the generic part
of the entry's header is used.
-j junk paths. The archive's directory structure is not recreated;
all files are deposited in the extraction directory (by default,
the current one).
-J [BeOS only] junk file attributes. The file's BeOS file
attributes are not restored, just the file's data.
-J [MacOS only] ignore MacOS extra fields. All Macintosh specific
info is skipped. Data-fork and resource-fork are restored as
separate files.
-K [AtheOS, BeOS, Unix only] retain SUID/SGID/Tacky file
attributes. Without this flag, these attribute bits are cleared
for security reasons.
-L convert to lowercase any filename originating on an uppercase-
only operating system or file system. (This was unzip's default
behavior in releases prior to 5.11; the new default behavior is
identical to the old behavior with the -U option, which is now
obsolete and will be removed in a future release.) Depending on
the archiver, files archived under single-case file systems
(VMS, old MS-DOS FAT, etc.) may be stored as all-uppercase
names; this can be ugly or inconvenient when extracting to a
case-preserving file system such as OS/2 HPFS or a case-sensi-
tive one such as under Unix. By default unzip lists and
extracts such filenames exactly as they're stored (excepting
truncation, conversion of unsupported characters, etc.); this
option causes the names of all files from certain systems to be
converted to lowercase. The -LL option forces conversion of
every filename to lowercase, regardless of the originating file
system.
-M pipe all output through an internal pager similar to the Unix
more(1) command. At the end of a screenful of output, unzip
pauses with a ``--More--'' prompt; the next screenful may be
viewed by pressing the Enter (Return) key or the space bar.
unzip can be terminated by pressing the ``q'' key and, on some
systems, the Enter/Return key. Unlike Unix more(1), there is no
forward-searching or editing capability. Also, unzip doesn't
notice if long lines wrap at the edge of the screen, effectively
resulting in the printing of two or more lines and the likeli-
hood that some text will scroll off the top of the screen before
being viewed. On some systems the number of available lines on
the screen is not detected, in which case unzip assumes the
height is 24 lines.
-n never overwrite existing files. If a file already exists, skip
the extraction of that file without prompting. By default unzip
queries before extracting any file that already exists; the user
may choose to overwrite only the current file, overwrite all
files, skip extraction of the current file, skip extraction of
all existing files, or rename the current file.
-N [Amiga] extract file comments as Amiga filenotes. File comments
are created with the -c option of zip(1L), or with the -N option
of the Amiga port of zip(1L), which stores filenotes as com-
ments.
-o overwrite existing files without prompting. This is a dangerous
option, so use it with care. (It is often used with -f, how-
ever, and is the only way to overwrite directory EAs under
OS/2.)
-P password
use password to decrypt encrypted zipfile entries (if any).
THIS IS INSECURE! Many multi-user operating systems provide
ways for any user to see the current command line of any other
user; even on stand-alone systems there is always the threat of
over-the-shoulder peeking. Storing the plaintext password as
part of a command line in an automated script is even worse.
Whenever possible, use the non-echoing, interactive prompt to
enter passwords. (And where security is truly important, use
strong encryption such as Pretty Good Privacy instead of the
relatively weak encryption provided by standard zipfile utili-
ties.)
-q perform operations quietly (-qq = even quieter). Ordinarily
unzip prints the names of the files it's extracting or testing,
the extraction methods, any file or zipfile comments that may be
stored in the archive, and possibly a summary when finished with
each archive. The -q[q] options suppress the printing of some
or all of these messages.
-s [OS/2, NT, MS-DOS] convert spaces in filenames to underscores.
Since all PC operating systems allow spaces in filenames, unzip
by default extracts filenames with spaces intact (e.g.,
``EA DATA. SF''). This can be awkward, however, since MS-DOS in
particular does not gracefully support spaces in filenames.
Conversion of spaces to underscores can eliminate the awkward-
ness in some cases.
-S [VMS] convert text files (-a, -aa) into Stream_LF record format,
instead of the text-file default, variable-length record format.
(Stream_LF is the default record format of VMS unzip. It is
applied unless conversion (-a, -aa and/or -b, -bb) is requested
or a VMS-specific entry is processed.)
-U [UNICODE_SUPPORT only] modify or disable UTF-8 handling. When
UNICODE_SUPPORT is available, the option -U forces unzip to
escape all non-ASCII characters from UTF-8 coded filenames as
``#Uxxxx'' (for UCS-2 characters, or ``#Lxxxxxx'' for unicode
codepoints needing 3 octets). This option is mainly provided
for debugging purpose when the fairly new UTF-8 support is sus-
pected to mangle up extracted filenames.
The option -UU allows to entirely disable the recognition of
UTF-8 encoded filenames. The handling of filename codings
within unzip falls back to the behaviour of previous versions.
[old, obsolete usage] leave filenames uppercase if created under
MS-DOS, VMS, etc. See -L above.
-V retain (VMS) file version numbers. VMS files can be stored with
a version number, in the format file.ext;##. By default the
``;##'' version numbers are stripped, but this option allows
them to be retained. (On file systems that limit filenames to
particularly short lengths, the version numbers may be truncated
or stripped regardless of this option.)
-W [only when WILD_STOP_AT_DIR compile-time option enabled] modi-
fies the pattern matching routine so that both `?' (single-char
wildcard) and `*' (multi-char wildcard) do not match the direc-
tory separator character `/'. (The two-character sequence
``**'' acts as a multi-char wildcard that includes the directory
separator in its matched characters.) Examples:
"*.c" matches "foo.c" but not "mydir/foo.c"
"**.c" matches both "foo.c" and "mydir/foo.c"
"*/*.c" matches "bar/foo.c" but not "baz/bar/foo.c"
"??*/*" matches "ab/foo" and "abc/foo"
but not "a/foo" or "a/b/foo"
This modified behaviour is equivalent to the pattern matching
style used by the shells of some of UnZip's supported target OSs
(one example is Acorn RISC OS). This option may not be avail-
able on systems where the Zip archive's internal directory sepa-
rator character `/' is allowed as regular character in native
operating system filenames. (Currently, UnZip uses the same
pattern matching rules for both wildcard zipfile specifications
and zip entry selection patterns in most ports. For systems
allowing `/' as regular filename character, the -W option would
not work as expected on a wildcard zipfile specification.)
-X [VMS, Unix, OS/2, NT, Tandem] restore owner/protection info
(UICs and ACL entries) under VMS, or user and group info
(UID/GID) under Unix, or access control lists (ACLs) under cer-
tain network-enabled versions of OS/2 (Warp Server with IBM LAN
Server/Requester 3.0 to 5.0; Warp Connect with IBM Peer 1.0), or
security ACLs under Windows NT. In most cases this will require
special system privileges, and doubling the option (-XX) under
NT instructs unzip to use privileges for extraction; but under
Unix, for example, a user who belongs to several groups can
restore files owned by any of those groups, as long as the user
IDs match his or her own. Note that ordinary file attributes
are always restored--this option applies only to optional, extra
ownership info available on some operating systems. [NT's
access control lists do not appear to be especially compatible
with OS/2's, so no attempt is made at cross-platform portability
of access privileges. It is not clear under what conditions
this would ever be useful anyway.]
-Y [VMS] treat archived file name endings of ``.nnn'' (where
``nnn'' is a decimal number) as if they were VMS version num-
bers (``;nnn''). (The default is to treat them as file types.)
Example:
"a.b.3" -> "a.b;3".
-$ [MS-DOS, OS/2, NT] restore the volume label if the extraction
medium is removable (e.g., a diskette). Doubling the option
(-$$) allows fixed media (hard disks) to be labelled as well.
By default, volume labels are ignored.
-/ extensions
[Acorn only] overrides the extension list supplied by Unzip$Ext
environment variable. During extraction, filename extensions
that match one of the items in this extension list are swapped
in front of the base name of the extracted file.
-: [all but Acorn, VM/CMS, MVS, Tandem] allows to extract archive
members into locations outside of the current `` extraction root
folder''. For security reasons, unzip normally removes ``parent
dir'' path components (``../'') from the names of extracted
file. This safety feature (new for version 5.50) prevents unzip
from accidentally writing files to ``sensitive'' areas outside
the active extraction folder tree head. The -: option lets
unzip switch back to its previous, more liberal behaviour, to
allow exact extraction of (older) archives that used ``../''
components to create multiple directory trees at the level of
the current extraction folder. This option does not enable
writing explicitly to the root directory (``/''). To achieve
this, it is necessary to set the extraction target folder to
root (e.g. -d / ). However, when the -: option is specified, it
is still possible to implicitly write to the root directory by
specifying enough ``../'' path components within the zip
archive. Use this option with extreme caution.
-^ [Unix only] allow control characters in names of extracted ZIP
archive entries. On Unix, a file name may contain any (8-bit)
character code with the two exception '/' (directory delimiter)
and NUL (0x00, the C string termination indicator), unless the
specific file system has more restrictive conventions. Gener-
ally, this allows to embed ASCII control characters (or even
sophisticated control sequences) in file names, at least on
'native' Unix file systems. However, it may be highly suspi-
cious to make use of this Unix "feature". Embedded control
characters in file names might have nasty side effects when dis-
played on screen by some listing code without sufficient filter-
ing. And, for ordinary users, it may be difficult to handle
such file names (e.g. when trying to specify it for open, copy,
move, or delete operations). Therefore, unzip applies a filter
by default that removes potentially dangerous control characters
from the extracted file names. The -^ option allows to override
this filter in the rare case that embedded filename control
characters are to be intentionally restored.
-2 [VMS] force unconditionally conversion of file names to
ODS2-compatible names. The default is to exploit the destina-
tion file system, preserving case and extended file name charac-
ters on an ODS5 destination file system; and applying the
ODS2-compatibility file name filtering on an ODS2 destination
file system.
ENVIRONMENT OPTIONS
unzip's default behavior may be modified via options placed in an envi-
ronment variable. This can be done with any option, but it is probably
most useful with the -a, -L, -C, -q, -o, or -n modifiers: make unzip
auto-convert text files by default, make it convert filenames from
uppercase systems to lowercase, make it match names case-insensitively,
make it quieter, or make it always overwrite or never overwrite files
as it extracts them. For example, to make unzip act as quietly as pos-
sible, only reporting errors, one would use one of the following com-
mands:
Unix Bourne shell:
UNZIP=-qq; export UNZIP
Unix C shell:
setenv UNZIP -qq
OS/2 or MS-DOS:
set UNZIP=-qq
VMS (quotes for lowercase):
define UNZIP_OPTS "-qq"
Environment options are, in effect, considered to be just like any
other command-line options, except that they are effectively the first
options on the command line. To override an environment option, one
may use the ``minus operator'' to remove it. For instance, to override
one of the quiet-flags in the example above, use the command
unzip --q[other options] zipfile
The first hyphen is the normal switch character, and the second is a
minus sign, acting on the q option. Thus the effect here is to cancel
one quantum of quietness. To cancel both quiet flags, two (or more)
minuses may be used:
unzip -t--q zipfile
unzip ---qt zipfile
(the two are equivalent). This may seem awkward or confusing, but it
is reasonably intuitive: just ignore the first hyphen and go from
there. It is also consistent with the behavior of Unix nice(1).
As suggested by the examples above, the default variable names are
UNZIP_OPTS for VMS (where the symbol used to install unzip as a foreign
command would otherwise be confused with the environment variable), and
UNZIP for all other operating systems. For compatibility with zip(1L),
UNZIPOPT is also accepted (don't ask). If both UNZIP and UNZIPOPT are
defined, however, UNZIP takes precedence. unzip's diagnostic option
(-v with no zipfile name) can be used to check the values of all four
possible unzip and zipinfo environment variables.
The timezone variable (TZ) should be set according to the local time-
zone in order for the -f and -u to operate correctly. See the descrip-
tion of -f above for details. This variable may also be necessary to
get timestamps of extracted files to be set correctly. The WIN32
(Win9x/ME/NT4/2K/XP/2K3) port of unzip gets the timezone configuration
from the registry, assuming it is correctly set in the Control Panel.
The TZ variable is ignored for this port.
DECRYPTION
Encrypted archives are fully supported by Info-ZIP software, but due to
United States export restrictions, de-/encryption support might be dis-
abled in your compiled binary. However, since spring 2000, US export
restrictions have been liberated, and our source archives do now
include full crypt code. In case you need binary distributions with
crypt support enabled, see the file ``WHERE'' in any Info-ZIP source or
binary distribution for locations both inside and outside the US.
Some compiled versions of unzip may not support decryption. To check a
version for crypt support, either attempt to test or extract an
encrypted archive, or else check unzip's diagnostic screen (see the -v
option above) for ``[decryption]'' as one of the special compilation
options.
As noted above, the -P option may be used to supply a password on the
command line, but at a cost in security. The preferred decryption
method is simply to extract normally; if a zipfile member is encrypted,
unzip will prompt for the password without echoing what is typed.
unzip continues to use the same password as long as it appears to be
valid, by testing a 12-byte header on each file. The correct password
will always check out against the header, but there is a 1-in-256
chance that an incorrect password will as well. (This is a security
feature of the PKWARE zipfile format; it helps prevent brute-force
attacks that might otherwise gain a large speed advantage by testing
only the header.) In the case that an incorrect password is given but
it passes the header test anyway, either an incorrect CRC will be gen-
erated for the extracted data or else unzip will fail during the
extraction because the ``decrypted'' bytes do not constitute a valid
compressed data stream.
If the first password fails the header check on some file, unzip will
prompt for another password, and so on until all files are extracted.
If a password is not known, entering a null password (that is, just a
carriage return or ``Enter'') is taken as a signal to skip all further
prompting. Only unencrypted files in the archive(s) will thereafter be
extracted. (In fact, that's not quite true; older versions of zip(1L)
and zipcloak(1L) allowed null passwords, so unzip checks each encrypted
file to see if the null password works. This may result in ``false
positives'' and extraction errors, as noted above.)
Archives encrypted with 8-bit passwords (for example, passwords with
accented European characters) may not be portable across systems and/or
other archivers. This problem stems from the use of multiple encoding
methods for such characters, including Latin-1 (ISO 8859-1) and OEM
code page 850. DOS PKZIP 2.04g uses the OEM code page; Windows PKZIP
2.50 uses Latin-1 (and is therefore incompatible with DOS PKZIP); Info-
ZIP uses the OEM code page on DOS, OS/2 and Win3.x ports but ISO coding
(Latin-1 etc.) everywhere else; and Nico Mak's WinZip 6.x does not
allow 8-bit passwords at all. UnZip 5.3 (or newer) attempts to use the
default character set first (e.g., Latin-1), followed by the alternate
one (e.g., OEM code page) to test passwords. On EBCDIC systems, if
both of these fail, EBCDIC encoding will be tested as a last resort.
(EBCDIC is not tested on non-EBCDIC systems, because there are no known
archivers that encrypt using EBCDIC encoding.) ISO character encodings
other than Latin-1 are not supported. The new addition of (partially)
Unicode (resp. UTF-8) support in UnZip 6.0 has not yet been adapted to
the encryption password handling in unzip. On systems that use UTF-8
as native character encoding, unzip simply tries decryption with the
native UTF-8 encoded password; the built-in attempts to check the pass-
word in translated encoding have not yet been adapted for UTF-8 support
and will consequently fail.
EXAMPLES
To use unzip to extract all members of the archive letters.zip into the
current directory and subdirectories below it, creating any subdirecto-
ries as necessary:
unzip letters
To extract all members of letters.zip into the current directory only:
unzip -j letters
To test letters.zip, printing only a summary message indicating whether
the archive is OK or not:
unzip -tq letters
To test all zipfiles in the current directory, printing only the sum-
maries:
unzip -tq \*.zip
(The backslash before the asterisk is only required if the shell
expands wildcards, as in Unix; double quotes could have been used
instead, as in the source examples below.) To extract to standard out-
put all members of letters.zip whose names end in .tex, auto-converting
to the local end-of-line convention and piping the output into more(1):
unzip -ca letters \*.tex | more
To extract the binary file paper1.dvi to standard output and pipe it to
a printing program:
unzip -p articles paper1.dvi | dvips
To extract all FORTRAN and C source files--*.f, *.c, *.h, and Make-
file--into the /tmp directory:
unzip source.zip "*.[fch]" Makefile -d /tmp
(the double quotes are necessary only in Unix and only if globbing is
turned on). To extract all FORTRAN and C source files, regardless of
case (e.g., both *.c and *.C, and any makefile, Makefile, MAKEFILE or
similar):
unzip -C source.zip "*.[fch]" makefile -d /tmp
To extract any such files but convert any uppercase MS-DOS or VMS names
to lowercase and convert the line-endings of all of the files to the
local standard (without respect to any files that might be marked
``binary''):
unzip -aaCL source.zip "*.[fch]" makefile -d /tmp
To extract only newer versions of the files already in the current
directory, without querying (NOTE: be careful of unzipping in one
timezone a zipfile created in another--ZIP archives other than those
created by Zip 2.1 or later contain no timezone information, and a
``newer'' file from an eastern timezone may, in fact, be older):
unzip -fo sources
To extract newer versions of the files already in the current directory
and to create any files not already there (same caveat as previous
example):
unzip -uo sources
To display a diagnostic screen showing which unzip and zipinfo options
are stored in environment variables, whether decryption support was
compiled in, the compiler with which unzip was compiled, etc.:
unzip -v
In the last five examples, assume that UNZIP or UNZIP_OPTS is set to
-q. To do a singly quiet listing:
unzip -l file.zip
To do a doubly quiet listing:
unzip -ql file.zip
(Note that the ``.zip'' is generally not necessary.) To do a standard
listing:
unzip --ql file.zip
or
unzip -l-q file.zip
or
unzip -l--q file.zip
(Extra minuses in options don't hurt.)
TIPS
The current maintainer, being a lazy sort, finds it very useful to
define a pair of aliases: tt for ``unzip -tq'' and ii for ``unzip -Z''
(or ``zipinfo''). One may then simply type ``tt zipfile'' to test an
archive, something that is worth making a habit of doing. With luck
unzip will report ``No errors detected in compressed data of zip-
file.zip,'' after which one may breathe a sigh of relief.
The maintainer also finds it useful to set the UNZIP environment vari-
able to ``-aL'' and is tempted to add ``-C'' as well. His ZIPINFO
variable is set to ``-z''.
DIAGNOSTICS
The exit status (or error level) approximates the exit codes defined by
PKWARE and takes on the following values, except under VMS:
0 normal; no errors or warnings detected.
1 one or more warning errors were encountered, but process-
ing completed successfully anyway. This includes zip-
files where one or more files was skipped due to unsup-
ported compression method or encryption with an unknown
password.
2 a generic error in the zipfile format was detected. Pro-
cessing may have completed successfully anyway; some bro-
ken zipfiles created by other archivers have simple work-
arounds.
3 a severe error in the zipfile format was detected. Pro-
cessing probably failed immediately.
4 unzip was unable to allocate memory for one or more
buffers during program initialization.
5 unzip was unable to allocate memory or unable to obtain a
tty to read the decryption password(s).
6 unzip was unable to allocate memory during decompression
to disk.
7 unzip was unable to allocate memory during in-memory
decompression.
8 [currently not used]
9 the specified zipfiles were not found.
10 invalid options were specified on the command line.
11 no matching files were found.
50 the disk is (or was) full during extraction.
51 the end of the ZIP archive was encountered prematurely.
80 the user aborted unzip prematurely with control-C (or
similar)
81 testing or extraction of one or more files failed due to
unsupported compression methods or unsupported decryp-
tion.
82 no files were found due to bad decryption password(s).
(If even one file is successfully processed, however, the
exit status is 1.)
VMS interprets standard Unix (or PC) return values as other, scarier-
looking things, so unzip instead maps them into VMS-style status codes.
The current mapping is as follows: 1 (success) for normal exit,
0x7fff0001 for warning errors, and (0x7fff000? + 16*nor-
mal_unzip_exit_status) for all other errors, where the `?' is 2 (error)
for unzip values 2, 9-11 and 80-82, and 4 (fatal error) for the remain-
ing ones (3-8, 50, 51). In addition, there is a compilation option to
expand upon this behavior: defining RETURN_CODES results in a human-
readable explanation of what the error status means.
BUGS
Multi-part archives are not yet supported, except in conjunction with
zip. (All parts must be concatenated together in order, and then ``zip
-F'' (for zip 2.x) or ``zip -FF'' (for zip 3.x) must be performed on
the concatenated archive in order to ``fix'' it. Also, zip 3.0 and
later can combine multi-part (split) archives into a combined single-
file archive using ``zip -s- inarchive -O outarchive''. See the zip 3
manual page for more information.) This will definitely be corrected
in the next major release.
Archives read from standard input are not yet supported, except with
funzip (and then only the first member of the archive can be
extracted).
Archives encrypted with 8-bit passwords (e.g., passwords with accented
European characters) may not be portable across systems and/or other
archivers. See the discussion in DECRYPTION above.
unzip's -M (``more'') option tries to take into account automatic wrap-
ping of long lines. However, the code may fail to detect the correct
wrapping locations. First, TAB characters (and similar control
sequences) are not taken into account, they are handled as ordinary
printable characters. Second, depending on the actual system / OS
port, unzip may not detect the true screen geometry but rather rely on
"commonly used" default dimensions. The correct handling of tabs would
require the implementation of a query for the actual tabulator setup on
the output console.
Dates, times and permissions of stored directories are not restored
except under Unix. (On Windows NT and successors, timestamps are now
restored.)
[MS-DOS] When extracting or testing files from an archive on a defec-
tive floppy diskette, if the ``Fail'' option is chosen from DOS's
``Abort, Retry, Fail?'' message, older versions of unzip may hang the
system, requiring a reboot. This problem appears to be fixed, but con-
trol-C (or control-Break) can still be used to terminate unzip.
Under DEC Ultrix, unzip would sometimes fail on long zipfiles (bad CRC,
not always reproducible). This was apparently due either to a hardware
bug (cache memory) or an operating system bug (improper handling of
page faults?). Since Ultrix has been abandoned in favor of Digital
Unix (OSF/1), this may not be an issue anymore.
[Unix] Unix special files such as FIFO buffers (named pipes), block
devices and character devices are not restored even if they are somehow
represented in the zipfile, nor are hard-linked files relinked. Basi-
cally the only file types restored by unzip are regular files, directo-
ries and symbolic (soft) links.
[OS/2] Extended attributes for existing directories are only updated if
the -o (``overwrite all'') option is given. This is a limitation of
the operating system; because directories only have a creation time
associated with them, unzip has no way to determine whether the stored
attributes are newer or older than those on disk. In practice this may
mean a two-pass approach is required: first unpack the archive nor-
mally (with or without freshening/updating existing files), then
overwrite just the directory entries (e.g., ``unzip -o foo */'').
[VMS] When extracting to another directory, only the [.foo] syntax is
accepted for the -d option; the simple Unix foo syntax is silently
ignored (as is the less common VMS foo.dir syntax).
[VMS] When the file being extracted already exists, unzip's query only
allows skipping, overwriting or renaming; there should additionally be
a choice for creating a new version of the file. In fact, the ``over-
write'' choice does create a new version; the old version is not over-
written or deleted.

maintenance); Steve Salisbury (Win32); Steve Miller (Windows CE GUI),
Johnny Lee (MS-DOS, Win32, Zip64); and Dave Smith (Tandem NSK).
The following people were former members of the Info-ZIP development
group and provided major contributions to key parts of the current
code: Greg ``Cave Newt'' Roelofs (UnZip, unshrink decompression); Jean-
loup Gailly (deflate compression); Mark Adler (inflate decompression,
fUnZip).
The author of the original unzip code upon which Info-ZIP's was based
is Samuel H. Smith; Carl Mascott did the first Unix port; and David P.
Kirschbaum organized and led Info-ZIP in its early days with Keith
Petersen hosting the original mailing list at WSMR-SimTel20. The full
list of contributors to UnZip has grown quite large; please refer to
the CONTRIBS file in the UnZip source distribution for a relatively
complete version.

2005-09-16 SMS.
On VMS, when output is redirected to a file, as in a command like
"PIPE UNZIP -v > X.OUT", the output file is created with VFC record
format, and multiple calls to write() or fwrite() will produce multiple
records, even when there's no newline terminator in the buffer.
The result is unsightly output with spurious newlines. Using fprintf()
instead of write() here, and disabling a fflush(stdout) in UzpMessagePrnt()
below, together seem to solve the problem.
According to the C RTL manual, "The write and decc$record_write
functions always generate at least one record." Also, "[T]he fwrite
function always generates at least <number_items> records." So,
"fwrite(buf, len, 1, strm)" is much better ("1" record) than
"fwrite(buf, 1, len, strm)" ("len" (1-character) records, _really_
ugly), but neither is better than write(). Similarly, "The fflush
function always generates a record if there is unwritten data in the
buffer." Apparently fprintf() buffers the stuff somewhere, and puts
out a record (only) when it sees a newline.

/*---------------------------------------------------------------------------
The basic idea of this function is as follows. Since the central di-
rectory lies at the end of the zipfile and the member files lie at the
beginning or middle or wherever, it is not very desirable to simply
read a central directory entry, jump to the member and extract it, and
then jump back to the central directory. In the case of a large zipfile
this would lead to a whole lot of disk-grinding, especially if each mem-
ber file is small. Instead, we read from the central directory the per-
tinent information for a block of files, then go extract/test the whole
block. Thus this routine contains two small(er) loops within a very
large outer loop: the first of the small ones reads a block of files
from the central directory; the second extracts or tests each file; and
the outer one loops over blocks. There's some file-pointer positioning
stuff in between, but that's about it. Btw, it's because of this jump-
ing around that we can afford to be lenient if an error occurs in one of
the member files: we should still be able to go find the other members,
since we know the offset of each from the beginning of the zipfile.

Parameters: archive = archive name
file = file contained in the archive. This cannot be
a wildcard to be meaningful
pattern = string to search for
cmd = 0 - case-insensitive search
1 - case-sensitve search
2 - case-insensitive, whole words only
3 - case-sensitive, whole words only
SkipBin = if true, skip any files that have control
characters other than CR, LF, or tab in the first
100 characters.
Returns: TRUE if a match is found
FALSE if no match is found
-1 on error
Comments: This does not pretend to be as useful as the standard
Unix grep, which returns the strings associated with a
particular pattern, nor does it search past the first
matching occurrence of the pattern.

---- --------- -------------- ------------------------------------
c1 30 Mar 92 M. Adler explode that uses huft_build from inflate
(this gives over a 70% speed improvement
over the original unimplode.c, which
decoded a bit at a time)
c2 4 Apr 92 M. Adler fixed bug for file sizes a multiple of 32k.
c3 10 Apr 92 M. Adler added a little memory tracking if DEBUG
c4 11 Apr 92 M. Adler added NOMEMCPY do kill use of memcpy()
c5 21 Apr 92 M. Adler added the WSIZE #define to allow reducing
the 32K window size for specialized
applications.
c6 31 May 92 M. Adler added typecasts to eliminate some warnings
c7 27 Jun 92 G. Roelofs added more typecasts.
c8 17 Oct 92 G. Roelofs changed ULONG/UWORD/byte to ulg/ush/uch.
c9 19 Jul 93 J. Bush added more typecasts (to return values);
made l[256] array static for Amiga.
c10 8 Oct 93 G. Roelofs added used_csize for diagnostics; added
buf and unshrink arguments to flush();
undef'd various macros at end for Turbo C;
removed NEXTBYTE macro (now in unzip.h)
and bytebuf variable (not used); changed
memset() to memzero().
c11 9 Jan 94 M. Adler fixed incorrect used_csize calculation.
c12 9 Apr 94 G. Roelofs fixed split comments on preprocessor lines
to avoid bug in Encore compiler.
c13 25 Aug 94 M. Adler fixed distance-length comment (orig c9 fix)
c14 22 Nov 95 S. Maxwell removed unnecessary "static" on auto array
c15 6 Jul 96 W. Haidinger added ulg typecasts to flush() calls.
c16 8 Feb 98 C. Spieler added ZCONST modifiers to const tables
and #ifdef DEBUG around debugging code.
c16b 25 Mar 98 C. Spieler modified DLL code for slide redirection.
c16d 05 Jul 99 C. Spieler take care of flush() return values and
stop processing in case of errors
c17 04 Feb 01 C. Spieler reorganized code to reduce repetitions
of large code parts; adapted huft decoding
to the changes in inflate's huft_build()
due to support of deflate64; fixed memory
leaks (huft tables were not free'd when
get_tree() failed).
c17b 16 Feb 02 C. Spieler changed type of the "extra lengths" array
"extra" from ush into uch (to save space)
c17c 10 Aug 04 NN file sizes use zoff_t.
c17d 01 Dec 07 C. Spieler type for file sizes changed from zoff_t
into zusz_t.

/*
Explode imploded (PKZIP method 6 compressed) data. This compression
method searches for as much of the current string of bytes (up to a length
of ~320) in the previous 4K or 8K bytes. If it doesn't find any matches
(of at least length 2 or 3), it codes the next byte. Otherwise, it codes
the length of the matched string and its distance backwards from the
current position. Single bytes ("literals") are preceded by a one (a
single bit) and are either uncoded (the eight bits go directly into the
compressed stream for a total of nine bits) or Huffman coded with a
supplied literal code tree. If literals are coded, then the minimum match
length is three, otherwise it is two.
There are therefore four kinds of imploded streams: 8K search with coded
literals (min match = 3), 4K search with coded literals (min match = 3),
8K with uncoded literals (min match = 2), and 4K with uncoded literals
(min match = 2). The kind of stream is identified in two bits of a
general purpose bit flag that is outside of the compressed stream.
Distance-length pairs for matched strings are preceded by a zero bit (to
distinguish them from literals) and are always coded. The distance comes
first and is either the low six (4K) or low seven (8K) bits of the
distance (uncoded), followed by the high six bits of the distance coded.
Then the length is six bits coded (0..63 + min match length), and if the
maximum such length is coded, then it's followed by another eight bits
(uncoded) to be added to the coded length. This gives a match length
range of 2..320 or 3..321 bytes.
The literal, length, and distance codes are all represented in a slightly
compressed form themselves. What is sent are the lengths of the codes for
each value, which is sufficient to construct the codes. Each byte of the
code representation is the code length (the low four bits representing
1..16), and the number of values sequentially with that length (the high
four bits also representing 1..16). There are 256 literal code values (if
literals are coded), 64 length code values, and 64 distance code values,
in that order at the beginning of the compressed stream. Each set of code
values is preceded (redundantly) with a byte indicating how many bytes are
in the code description that follows, in the range 1..256.
The codes themselves are decoded using tables made by huft_build() from
the bit lengths. That routine and its comments are in the inflate.c
module.

The UNIX unzip command, courtesy of the Info-ZIP project.
PROVENANCE
unzip610b.zip (circa 2010)

LICENSE
BSD-like with Apache-like requirement that changes be documented.
LOCAL CHANGES
The only way this software differs from the normal InfoZIP sources is
that we're linking the Cosmopolitan C Library, which enables it to be
built as an Actually Portable Executable.
Minor changes include:
- Normalization of header / build config for platform / repository
sed -i -e '/# *include *<.*/d' *.*
sed -i -e 's!# *include *"!#include "third_party/unzip/!' *.*
sed -i -e '1 i\// clang-format off' *.c *.h
- Fixed a lot of static analysis buffer overflow warnings.

/*---------------------------------------------------------------------------
globals.h
There is usually no need to include this file since unzip.h includes it.
This header file is used by all of the UnZip source files. It contains
a struct definition that is used to "house" all of the global variables.
This is done to allow for multithreaded environments (OS/2, NT, Win95,
Unix) to call UnZip through an API without a semaphore. REENTRANT should
be defined for all platforms that require this.
GLOBAL CONSTRUCTOR AND DESTRUCTOR (API WRITERS READ THIS!!!)
------------------------------------------------------------
No, it's not C++, but it's as close as we can get with K&R.
The main() of each process that uses these globals must include the
CONSTRUCTGLOBALS; statement. This will malloc enough memory for the
structure and initialize any variables that require it. This must
also be done by any API function that jumps into the middle of the
code.
The DESTROYGLOBALS(); statement should be inserted before EVERY "EXIT(n)".
Naturally, it also needs to be put before any API returns as well.
In fact, it's much more important in API functions since the process
will NOT end, and therefore the memory WON'T automatically be freed
by the operating system.
USING VARIABLES FROM THE STRUCTURE
----------------------------------
All global variables must now be prefixed with `G.' which is either a
global struct (in which case it should be the only global variable) or
a macro for the value of a local pointer variable that is passed from
function to function. Yes, this is a pain. But it's the only way to
allow full reentrancy.
ADDING VARIABLES TO THE STRUCTURE
---------------------------------
If you make the inclusion of any variables conditional, be sure to only
check macros that are GUARANTEED to be included in every module.
For instance, newzip and pwdarg are needed only if CRYPT is TRUE,
but this is defined after unzip.h has been read. If you are not careful,
some modules will expect your variable to be part of this struct while
others won't. This will cause BIG problems. (Inexplicable crashes at
strange times, car fires, etc.) When in doubt, always include it!
Note also that UnZipSFX needs a few variables that UnZip doesn't. However,
it also includes some object files from UnZip. If we were to conditionally
include the extra variables that UnZipSFX needs, the object files from
UnZip would not mesh with the UnZipSFX object files. Result: we just
include the UnZipSFX variables every time. (It's only an extra 4 bytes
so who cares!)
ADDING FUNCTIONS
----------------
To support this new global struct, all functions must now conditionally
pass the globals pointer (pG) to each other. This is supported by 5 macros:
__GPRO, __GPRO__, __G, __G__ and __GDEF. A function that needs no other
parameters would look like this:
int extract_or_test_files(__G)
__GDEF
{
... stuff ...
}
A function with other parameters would look like:
int memextract(__G__ tgt, tgtsize, src, srcsize)
__GDEF
uch *tgt, *src;
ulg tgtsize, srcsize;
{
... stuff ...
}
In the Function Prototypes section of unzpriv.h, you should use __GPRO and
__GPRO__ instead:
int uz_opts OF((__GPRO__ int *pargc, char ***pargv));
int process_zipfiles OF((__GPRO));
Note that there is NO comma after __G__ or __GPRO__ and no semi-colon after
__GDEF. I wish there was another way but I don't think there is.
TESTING THE CODE
-----------------
Whether your platform requires reentrancy or not, you should always try
building with REENTRANT defined if any functions have been added. It is
pretty easy to forget a __G__ or a __GDEF and this mistake will only show
up if REENTRANT is defined. All platforms should run with REENTRANT
defined. Platforms that can't take advantage of it will just be paying
a performance penalty needlessly.
SIGNAL MADNESS
--------------
This whole pointer passing scheme falls apart when it comes to SIGNALs.
I handle this situation 2 ways right now. If you define USETHREADID,
UnZip will include a 64-entry table. Each entry can hold a global
pointer and thread ID for one thread. This should allow up to 64
threads to access UnZip simultaneously. Calling DESTROYGLOBALS()
will free the global struct and zero the table entry. If somebody
forgets to call DESTROYGLOBALS(), this table will eventually fill up
and UnZip will exit with an error message. A good way to test your
code to make sure you didn't forget a DESTROYGLOBALS() is to change
THREADID_ENTRIES to 3 or 4 in globals.c, making the table real small.
Then make a small test program that calls your API a dozen times.
Those platforms that don't have threads still need to be able to compile
with REENTRANT defined to test and see if new code is correctly written
to work either way. For these platforms, I simply keep a global pointer
called GG that points to the Globals structure. Good enough for testing.
I believe that NT has thread level storage. This could probably be used
to store a global pointer for the sake of the signal handler more cleanly
than my table approach.

* interactive command line of the normal program executables.

* c) The Win32 DLL API with a pure binary interface which can be used to
* build GUI mode as well as Console mode applications.

This file contains the "fatal error" callback routine required by the
"minimal" (silent, non-stdio) setup of the bzip2 compression library.
The fatal bzip2 error bail-out routine is provided in a separate code
module, so that it can be easily overridden when the UnZip package is
used as a static link library. One example is the WinDLL static library
usage for building a monolythic binary of the Windows application "WiZ"
that supports bzip2 both in compression and decompression operations.

NOTES APPLICABLE TO ALL STRING FUNCTIONS:
All of the x_to_y functions take parameters for an output buffer and
its available length, and return an int. The value returned is the
length of the string that the input produces, which may be larger than
the provided buffer length. If the returned value is less than the
buffer length, then the contents of the buffer will be null-terminated;
otherwise, it will not be terminated and may be invalid, possibly
stopping in the middle of a multibyte sequence.
In all cases you may pass NULL as the buffer and/or 0 as the length, if
you just want to learn how much space the string is going to require.
The functions will return -1 if the input is invalid UTF-8 or cannot be
encoded as UTF-8.

/* wide_to_escape_string
provides a string that represents a wide char not in local char set
An initial try at an algorithm. Suggestions welcome.
According to the standard, Unicode character points are restricted to
the number range from 0 to 0x10FFFF, respective 21 bits.
For a hexadecimal notation, 2 octets are sufficient for the mostly
used characters from the "Basic Multilingual Plane", all other
Unicode characters can be represented by 3 octets (= 6 hex digits).
The Unicode standard suggests to write Unicode character points
as 4 resp. 6 hex digits, preprended by "U+".
(e.g.: U+10FFFF for the highest character point, or U+0030 for the ASCII
digit "0")
However, for the purpose of escaping non-ASCII chars in an ASCII character
stream, the "U" is not a very good escape initializer. Therefore, we
use the following convention within our Info-ZIP code:
If not an ASCII char probably need 2 bytes at least. So if
a 2-byte wide encode it as 4 hex digits with a leading #U. If
needs 3 bytes then prefix the string with #L. So
#U1234
is a 2-byte wide character with bytes 0x12 and 0x34 while
#L123456
is a 3-byte wide character with bytes 0x12, 0x34, 0x56.
On Windows, wide that need two wide characters need to be converted
to a single number.

If a valid block is found, the time stamps are copied to the iztimes
structure (provided the z_utim pointer is not NULL).
If a IZUNIX2 block is found or the IZUNIX block contains UID/GID fields,
and the z_uidgid array pointer is valid (!= NULL), the owner info is
transfered as well.
The presence of an EF_TIME or EF_IZUNIX2 block results in ignoring all
data from probably present obsolete EF_IZUNIX blocks.
If multiple blocks of the same type are found, only the information from
the last block is used.
The return value is a combination of the EF_TIME Flags field with an
additional flag bit indicating the presence of valid UID/GID info,
or 0 in case of failure.

/* For the encoding task used in Zip (and ZipCloak), we want to initialize
the crypt algorithm with some reasonably unpredictable bytes, see
the crypthead() function. The standard rand() library function is
used to supply these `random' bytes, which in turn is initialized by
a srand() call. The srand() function takes an "unsigned" (at least 16bit)
seed value as argument to determine the starting point of the rand()
pseudo-random number generator.
This seed number is constructed as "Seed = Seed1 .XOR. Seed2" with
Seed1 supplied by the current time (= "(unsigned)time()") and Seed2
as some (hopefully) nondeterministic bitmask. On many (most) systems,
we use some "process specific" number, as the PID or something similar,
but when nothing unpredictable is available, a fixed number may be
sufficient.
NOTE:
1.) This implementation requires the availability of the following
standard UNIX C runtime library functions: time(), rand(), srand().
On systems where some of them are missing, the environment that
incorporates the crypt routines must supply suitable replacement
functions.
2.) It is a very bad idea to use a second call to time() to set the
"Seed2" number! In this case, both "Seed1" and "Seed2" would be
(almost) identical, resulting in a (mostly) "zero" constant seed
number passed to srand().
The implementation environment defined in the "zip.h" header should
supply a reasonable definition for ZCR_SEED2 (an unsigned number; for
most implementations of rand() and srand(), only the lower 16 bits are
significant!). An example that works on many systems would be
"#define ZCR_SEED2 (unsigned)getpid()".
The default definition for ZCR_SEED2 supplied below should be regarded
as a fallback to allow successful compilation in "beta state"
environments.

b2 21 Mar 92 M. Adler fixed bug in fixed-code blocks
b3 22 Mar 92 M. Adler sped up match copies, cleaned up some
b4 25 Mar 92 M. Adler added prototypes; removed window[] (now
is the responsibility of unzip.h--also
changed name to slide[]), so needs diffs
for unzip.c and unzip.h (this allows
compiling in the small model on MSDOS);

changed BMAX to 16 for explode. Removed
OUTB usage, and replaced it with flush()--
this was a 20% speed improvement! Added
an explode.c (to replace unimplod.c) that
uses the huft routines here. Removed
register union.

/*
Inflate deflated (PKZIP's method 8 compressed) data. The compression
method searches for as much of the current string of bytes (up to a
length of 258) in the previous 32K bytes. If it doesn't find any
matches (of at least length 3), it codes the next byte. Otherwise, it
codes the length of the matched string and its distance backwards from
the current position. There is a single Huffman code that codes both
single bytes (called "literals") and match lengths. A second Huffman
code codes the distance information, which follows a length code. Each
length or distance code actually represents a base value and a number
of "extra" (sometimes zero) bits to get to add to the base value. At
the end of each deflated block is a special end-of-block (EOB) literal/
length code. The decoding process is basically: get a literal/length
code; if EOB then done; if a literal, emit the decoded byte; if a
length then get the distance and emit the referred-to bytes from the
sliding window of previously emitted data.
There are (currently) three kinds of inflate blocks: stored, fixed, and
dynamic. The compressor outputs a chunk of data at a time and decides
which method to use on a chunk-by-chunk basis. A chunk might typically
be 32K to 64K, uncompressed. If the chunk is uncompressible, then the
"stored" method is used. In this case, the bytes are simply stored as
is, eight bits per byte, with none of the above coding. The bytes are
preceded by a count, since there is no longer an EOB code.
If the data are compressible, then either the fixed or dynamic methods
are used. In the dynamic method, the compressed data are preceded by
an encoding of the literal/length and distance Huffman codes that are
to be used to decode this block. The representation is itself Huffman
coded, and so is preceded by a description of that code. These code
descriptions take up a little space, and so for small blocks, there is
a predefined set of codes, called the fixed codes. The fixed method is
used if the block ends up smaller that way (usually for quite small
chunks); otherwise the dynamic method is used. In the latter case, the
codes are customized to the probabilities in the current block and so
can code it much better than the pre-determined fixed codes can.
The Huffman codes themselves are decoded using a multi-level table
lookup, in order to maximize the speed of decoding plus the speed of
building the decoding tables. See the comments below that precede the
lbits and dbits tuning parameters.
GRR: return values(?)
0 OK
1 incomplete table
2 bad input
3 not enough memory
the following return codes are passed through from FLUSH() errors
50 (PK_DISK) "overflow of output space"
80 (IZ_CTRLC) "canceled by user's request"
*/
/*
Notes beyond the 1.93a appnote.txt:
1. Distance pointers never point before the beginning of the output
stream.
2. Distance pointers can point back across blocks, up to 32k away.
3. There is an implied maximum of 7 bits for the bit length table and
15 bits for the actual data.
4. If only one code exists, then it is encoded using one bit. (Zero
would be more efficient, but perhaps a little confusing.) If two
codes exist, they are coded using one bit each (0 and 1).
5. There is no way of sending zero distance codes--a dummy must be
sent if there are none. (History: a pre 2.0 version of PKZIP would
store blocks with no distance codes, but this was discovered to be
too harsh a criterion.) Valid only for 1.93a. 2.04c does allow
zero distance codes, which is sent as one code of zero bits in
length.
6. There are up to 286 literal/length codes. Code 256 represents the
end-of-block. Note however that the static length tree defines
288 codes just to fill out the Huffman codes. Codes 286 and 287
cannot be used though, since there is no length base or extra bits
defined for them. Similarily, there are up to 30 distance codes.
However, static trees define 32 codes (all 5 bits) to fill out the
Huffman codes, but the last two had better not show up in the data.
7. Unzip can check dynamic Huffman blocks for complete code sets.
The exception is that a single code would not be complete (see #4).
8. The five bits following the block type is really the number of
literal codes sent minus 257.
9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits
(1+6+6). Therefore, to output three times the length, you output
three codes (1+1+1), whereas to output four times the same length,
you only need two codes (1+3). Hmm.
10. In the tree reconstruction algorithm, Code = Code + Increment
only if BitLength(i) is not zero. (Pretty obvious.)
11. Correction: 4 Bits: # of Bit Length codes - 4 (4 - 19)
12. Note: length code 284 can represent 227-258, but length code 285
really is 258. The last length deserves its own, short code
since it gets used a lot in very redundant files. The length
258 is special since 258 - 3 (the min match length) is 255.
13. The literal/length and distance code bit lengths are read as a
single stream of lengths. It is possible (and advantageous) for
a repeat code (16, 17, or 18) to go across the boundary between
the two sets of lengths.
14. The Deflate64 (PKZIP method 9) variant of the compression algorithm
differs from "classic" deflate in the following 3 aspect:
a) The size of the sliding history window is expanded to 64 kByte.
b) The previously unused distance codes #30 and #31 code distances
from 32769 to 49152 and 49153 to 65536. Both codes take 14 bits
of extra data to determine the exact position in their 16 kByte
range.
c) The last lit/length code #285 gets a different meaning. Instead
of coding a fixed maximum match length of 258, it is used as a
"generic" match length code, capable of coding any length from
3 (min match length + 0) to 65538 (min match length + 65535).
This means that the length code #285 takes 16 bits (!) of uncoded
extra data, added to a fixed min length of 3.
Changes a) and b) would have been transparent for valid deflated
data, but change c) requires to switch decoder configurations between
Deflate and Deflate64 modes.

/* Macros for inflate() bit peeking and grabbing.
The usage is:
NEEDBITS(j)
x = b & mask_bits[j];
DUMPBITS(j)
where NEEDBITS makes sure that b has at least j bits in it, and
DUMPBITS removes the bits from b. The macros use the variable k
for the number of bits in b. Normally, b and k are register
variables for speed and are initialized at the beginning of a
routine that uses these macros from a global bit buffer and count.
In order to not ask for more bits than there are in the compressed
stream, the Huffman tables are constructed to only ask for just
enough bits to make up the end-of-block code (value 256). Then no
bytes need to be "returned" to the buffer at the end of the last
block. See the huft_build() routine.
Actually, the precautions mentioned above are not sufficient to
prevent fetches of bits beyound the end of the last block in every
case. When the last code fetched before the end-of-block code was
a very short distance code (shorter than "distance-prefetch-bits" -
"end-of-block code bits"), this last distance code fetch already
exausts the available data. To prevent failure of extraction in this
case, the "read beyond EOF" check delays the raise of the "invalid
data" error until an actual overflow of "used data" is detected.
This error condition is only fulfilled when the "number of available
bits" counter k is found to be negative in the NEEDBITS() macro.
An alternate fix for that problem adjusts the size of the distance code
base table so that it does not exceed the length of the end-of-block code
plus the minimum length of a distance code. This alternate fix can be
enabled by defining the preprocessor symbol FIX_PAST_EOB_BY_TABLEADJUST.

/*
Huffman code decoding is performed using a multi-level table lookup.
The fastest way to decode is to simply build a lookup table whose
size is determined by the longest code. However, the time it takes
to build this table can also be a factor if the data being decoded
are not very long. The most common codes are necessarily the
shortest codes, so those codes dominate the decoding time, and hence
the speed. The idea is you can have a shorter table that decodes the
shorter, more probable codes, and then point to subsidiary tables for
the longer codes. The time it costs to decode the longer codes is
then traded against the time it takes to make longer tables.
This results of this trade are in the variables lbits and dbits
below. lbits is the number of bits the first level table for literal/
length codes can decode in one step, and dbits is the same thing for
the distance codes. Subsequent tables are also less than or equal to
those sizes. These values may be adjusted either when all of the
codes are shorter than that, in which case the longest code length in
bits is used, or when the shortest code is *longer* than the requested
table size, in which case the length of the shortest code in bits is
used.
There are two different values for the two tables, since they code a
different number of possibilities each. The literal/length table
codes 286 possible values, or in a flat code, a little over eight
bits. The distance table codes 30 possible values, or a little less
than five bits, flat. The optimum values for speed end up being
about one bit more than those, so lbits is 8+1 and dbits is 5+1.
The optimum values may differ though from machine to machine, and
possibly even between compilers. Your mileage may vary.

* locale_TZ as GetPlatformLocalTimezone(), for use as a generic

ebcdic.h
The CECP 1047 (Extended de-facto EBCDIC) <-> ISO 8859-1 conversion tables,
from ftp://aix1.segi.ulg.ac.be/pub/docs/iso8859/iso8859.networking
NOTES:
<[email protected]> (OS/390 port 12/97)
These table no longer represent the standard mappings (for example in the
OS/390 iconv utility). In order to follow current standards I remapped
ebcdic x0a to ascii x15 and
ebcdic x85 to ascii x25 (and vice-versa)
Without these changes, newlines in auto-convert text files appeared
as literal \045.
I'm not sure what effect this remap would have on the MVS and CMS ports, so
I ifdef'd these changes. Hopefully these ifdef's can be removed when the
MVS/CMS folks test the new mappings.
Christian Spieler <[email protected]>, 27-Apr-1998
The problem mentioned by Paul von Behren was already observed previously
on VM/CMS, during the preparation of the CMS&MVS port of UnZip 5.20 in
1996. At that point, the ebcdic tables were not changed since they seemed
to be an adopted standard (to my knowledge, these tables are still used
as presented in mainfraime KERMIT). Instead, the "end-of-line" conversion
feature of Zip's and UnZip's "text-translation" mode was used to force
correct mappings between ASCII and EBCDIC newline markers.
Before interchanging the ASCII mappings of the EBCDIC control characters
"NL" 0x25 and "LF" 0x15 according to the OS/390 setting, we have to
make sure that EBCDIC 0x15 is never used as line termination.

UnZip - a zipfile extraction utility. See below for make instructions, or
read the comments in Makefile and the various Contents files for more de-
tailed explanations. To report a bug, submit a *complete* description via
//www.info-zip.org/zip-bug.html; include machine type, operating system and
version, compiler and version, and reasonably detailed error messages or
problem report. To join Info-ZIP, see the instructions in README.
UnZip 5.x is a greatly expanded and partially rewritten successor to 4.x,
which in turn was almost a complete rewrite of version 3.x. For a detailed
revision history, see UnzpHist.zip at quest.jpl.nasa.gov. For a list of
the many (near infinite) contributors, see "CONTRIBS" in the UnZip source
distribution. (Some of this information is outdated and needs to be
updated.)
UnZip 6.0 adds support for archives larger than 4 GiB using the Zip64
extensions as well as support for Unicode information embedded per the
latest zip standard additions.
---------------------------------------------------------------------------
[from original zipinfo.c]
This program reads great gobs of totally nifty information, including the
central directory stuff, from ZIP archives ("zipfiles" for short). It
started as just a testbed for fooling with zipfiles, but at this point it
is actually a useful utility. It also became the basis for the rewrite of
UnZip (3.16 -> 4.0), using the central directory for processing rather than
the individual (local) file headers.
As of ZipInfo v2.0 and UnZip v5.1, the two programs are combined into one.
If the executable is named "unzip" (or "unzip.exe", depending), it behaves
like UnZip by default; if it is named "zipinfo" or "ii", it behaves like
ZipInfo. The ZipInfo behavior may also be triggered by use of unzip's -Z
option; for example, "unzip -Z [zipinfo_options] archive.zip".
Another dandy product from your buddies at Newtware!

/*---------------------------------------------------------------
* Long option support
* 8/23/2003
* Updated 3/1/2008 to support UnZip
*
* Defines function get_option() to get and process the command
* line options and arguments from argv[]. The caller calls
* get_option() in a loop to get either one option and possible
* value or a non-option argument each loop.
*
* This version has been modified to work with UnZip and ZipInfo.
* the major changes are removing the error returns, instead
* passing back error codes for errors, and supporting separate
* groups of options for UnZip and ZipInfo and selecting the option
* group by an argument.
*
* This version does not include argument file support and can
* work directly on argv. The argument file code complicates things and
* it seemed best to leave it out for now. If argument file support
* (reading in command line arguments stored in a file and inserting into
* command line where @filename is found) is added later the arguments
* can change and a freeable copy of argv will be needed and can be
* created using copy_args in the left out code.
*
* Supports short and long options as defined in the array options[]
* in zip.c, multiple short options in an argument (like -jlv), long
* option abbreviation (like --te for --temp-file if --te unique),
* short and long option values (like -b filename or --temp-file filename
* or --temp-file=filename), optional and required values, option negation
* by trailing - (like -S- to not include hidden and system files in MSDOS),
* value lists (like -x a b c), argument permuting (returning all options
* and values before any non-option arguments), and argument files (where
* any non-option non-value argument in form @path gets substituted with
* the white space separated arguments in the text file at path). In this
* version argument file support has been removed to simplify development
* but may be added later.
*

/* get_option
*
* Main interface for user. Use this function to get options, values and
* non-option arguments from a command line provided in argv form.
*
* To use get_option() first define valid options by setting
* the global variable options[] to an array of option_struct. Also
* either change defaults below or make variables global and set elsewhere.
* Zip uses below defaults.
*
* Call get_option() to get an option (like -b or --temp-file) and any
* value for that option (like filename for -b) or a non-option argument
* (like archive name) each call. If *value* is not NULL after calling
* get_option() it is a returned value and the caller should either store
* the char pointer or free() it before calling get_option() again to avoid
* leaking memory. If a non-option non-value argument is returned get_option()
* returns o_NON_OPTION_ARG and value is set to the entire argument.
* When there are no more arguments get_option() returns 0.
*
* The parameters argnum (after set to 0 on initial call),
* optchar, first_nonopt_arg, option_num, and depth (after initial
* call) are set and maintained by get_option() and should not be
* changed. The parameters argc, negated, and value are outputs and
* can be used by the calling program. get_option() returns either the
* option_ID for the current option, a special value defined in
* zip.h, or 0 when no more arguments.
*
* The value returned by get_option() is the ID value in the options
* table. This value can be duplicated in the table if different
* options are really the same option. The index into the options[]
* table is given by option_num, though the ID should be used as
* option numbers change when the table is changed. The ID must
* not be 0 for any option as this ends the table. If get_option()
* finds an option not in the table it calls oERR to post an
* error and exit. Errors also result if the option requires a
* value that is missing, a value is present but the option does
* not take one, and an option is negated but is not
* negatable. Non-option arguments return o_NON_OPTION_ARG
* with the entire argument in value.
*
* For Zip and UnZip, permuting is on and all options and their values
* are returned before any non-option arguments like archive name.
*
* The arguments "-" alone and "--" alone return as non-option arguments.
* Note that "-" should not be used as part of a short option
* entry in the table but can be used in the middle of long
* options such as in the long option "a-long-option". Now "--" alone
* stops option processing, returning any arguments following "--" as
* non-option arguments instead of options.
*
* Argument file support is removed from this version. It may be added later.
*
* After each call:
* argc is set to the current size of args[] but should not change
* with argument file support removed,
* argnum is the index of the current arg,
* value is either the value of the returned option or non-option
* argument or NULL if option with no value,
* negated is set if the option was negated by a trailing dash (-)
* option_num is set to either the index in options[] for the option or
* o_NO_OPTION_MATCH if no match.
* Negation is checked before the value is read if the option is negatable so
* that the - is not included in the value. If the option is not negatable
* but takes a value then the - will start the value. If permuting then
* argnum and first_nonopt_arg are unreliable and should not be used.
*
* Command line is read from left to right. As get_option() finds non-option
* arguments (arguments not starting with - and that are not values to options)
* it moves later options and values in front of the non-option arguments.
* This permuting is turned off by setting enable_permute to 0. Then
* get_option() will return options and non-option arguments in the order
* found. Currently permuting is only done after an argument is completely
* processed so that any value can be moved with options they go with. All
* state information is stored in the parameters argnum, optchar,
* first_nonopt_arg and option_num. You should not change these after the
* first call to get_option(). If you need to back up to a previous arg then
* set argnum to that arg (remembering that args may have been permuted) and
* set optchar = 0 and first_nonopt_arg to the first non-option argument if
* permuting. After all arguments are returned the next call to get_option()
* returns 0. The caller can then call free_args(args) if appropriate.
*
* get_option() accepts arguments in the following forms:
* short options
* of 1 and 2 characters, e.g. a, b, cc, d, and ba, after a single
* leading -, as in -abccdba. In this example if 'b' is followed by 'a'
* it matches short option 'ba' else it is interpreted as short option
* b followed by another option. The character - is not legal as a
* short option or as part of a 2 character short option.
*
* If a short option has a value it immediately follows the option or
* if that option is the end of the arg then the next arg is used as
* the value. So if short option e has a value, it can be given as
* -evalue
* or
* -e value
* and now
* -e=value
* but now that = is optional a leading = is stripped for the first.
* This change allows optional short option values to be defaulted as
* -e=
* Either optional or required values can be specified. Optional values
* now use both forms as ignoring the later got confusing. Any
* non-value short options can preceed a valued short option as in
* -abevalue
* Some value types (one_char and number) allow options after the value
* so if oc is an option that takes a character and n takes a number
* then
* -abocVccn42evalue
* returns value V for oc and value 42 for n. All values are strings
* so programs may have to convert the "42" to a number. See long
* options below for how value lists are handled.
*
* Any short option can be negated by following it with -. Any - is
* handled and skipped over before any value is read unless the option
* is not negatable but takes a value and then - starts the value.
*
* If the value for an optional value is just =, then treated as no
* value.
*
* long options
* of arbitrary length are assumed if an arg starts with -- but is not
* exactly --. Long options are given one per arg and can be abbreviated
* if the abbreviation uniquely matches one of the long options.
* Exact matches always match before partial matches. If ambiguous an
* error is generated.
*
* Values are specified either in the form
* --longoption=value
* or can be the following arg if the value is required as in
* --longoption value
* Optional values to long options must be in the first form.
*
* Value lists are specified by o_VALUE_LIST and consist of an option
* that takes a value followed by one or more value arguments.
* The two forms are
* --option=value
* or
* -ovalue
* for a single value or
* --option value1 value2 value3 ... --option2
* or
* -o value1 value2 value3 ...
* for a list of values. The list ends at the next option, the
* end of the command line, or at a single "@" argument.
* Each value is treated as if it was preceeded by the option, so
* --option1 val1 val2
* with option1 value_type set to o_VALUE_LIST is the same as
* --option1=val1 --option1=val2
*
* Long options can be negated by following the option with - as in
* --longoption-
* Long options with values can also be negated if this makes sense for
* the caller as:
* --longoption-=value
* If = is not followed by anything it is treated as no value.
*
* @path
* Argument files support removed from this version. It may be added
* back later.
*
* non-option argument
* is any argument not given above. If enable_permute is 1 then
* these are returned after all options, otherwise all options and
* args are returned in order. Returns option ID o_NON_OPTION_ARG
* and sets value to the argument.
*
*
* Arguments to get_option:
* int option_group - either UZO for UnZip or ZIO for ZipInfo
* char ***pargs - pointer to arg array in the argv form
* int *argc - returns the current argc for args incl. args[0]
* int *argnum - the index of the current argument (caller
* should set = 0 on first call and not change
* after that)
* int *optchar - index of next short opt in arg or special
* int *first_nonopt_arg - used by get_option to permute args
* int *negated - option was negated (had trailing -)
* char *value - value of option if any (free when done with it)
* or NULL
* int *option_num - the index in options of the last option returned
* (can be o_NO_OPTION_MATCH)
* int recursion_depth - current depth of recursion
* (always set to 0 by caller)
* (always 0 with argument files support removed)
*
* Caller should only read the returned option ID and the value, negated,
* and option_num (if required) parameters after each call.

match.c
The match() routine recursively compares a string to a "pattern" (regular
expression), returning TRUE if a match is found or FALSE if not. This
version is specifically for use with unzip.c: as did the previous match()
routines from SEA and J. Kercheval, it leaves the case (upper, lower, or
mixed) of the string alone, but converts any uppercase characters in the
pattern to lowercase if indicated by the global var pInfo->lcflag (which
is to say, string is assumed to have been converted to lowercase already,
if such was necessary).
GRR: reversed order of text, pattern in matche() (now same as match());
added ignore_case/ic flags, Case() macro.
PaulK: replaced matche() with recmatch() from Zip, modified to have an
ignore_case argument; replaced test frame with simpler one.

Match the pattern (wildcard) against the string (fixed):
match(string, pattern, ignore_case, sepc);
returns TRUE if string matches pattern, FALSE otherwise. In the pattern:
`*' matches any sequence of characters (zero or more)
`?' matches any single character
[SET] matches any character in the specified set,
[!SET] or [^SET] matches any character not in the specified set.
A set is composed of characters or ranges; a range looks like ``character
hyphen character'' (as in 0-9 or A-Z). [0-9a-zA-Z_] is the minimal set of
characters allowed in the [..] pattern construct. Other characters are
allowed (i.e., 8-bit characters) if your system will support them.
To suppress the special syntactic significance of any of ``[]*?!^-\'', in-
side or outside a [..] construct, and match the character exactly, precede
it with a ``\'' (backslash).
Note that "*.*" and "*." are treated specially under MS-DOS if DOSWILD is
defined. See the DOSWILD section below for an explanation. Note also
that with VMSWILD defined, '%' is used instead of '?', and sets (ranges)
are delimited by () instead of [].

Generate tables for a byte-wise 32-bit CRC calculation on the polynomial:

Polynomials over GF(2) are represented in binary, one bit per coefficient,
with the lowest powers in the most significant bit. Then adding polynomials
is just exclusive-or, and multiplying a polynomial by x is a right shift by
one. If we call the above polynomial p, and represent a byte as the
polynomial q, also with the lowest power in the most significant bit (so the
byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
where a mod b means the remainder after dividing a by b.
This calculation is done using the shift-register method of multiplying and
taking the remainder. The register is initialized to zero, and for each
incoming bit, x^32 is added mod p to the register if the bit is a one (where
x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
x (which is shifting right by one and adding x^32 mod p if the bit shifted
out is a one). We start with the highest power (least significant bit) of
q and repeat for all eight bits of q.
The first (or only) table is simply the CRC of all possible eight bit values.
This is all the information needed to generate CRC's on data a byte-at-a-time
for all combinations of CRC register values and incoming bytes.
The remaining 3 tables (if IZ_CRCOPTIM_UNFOLDTBL is enabled) allow for
word-at-a-time CRC calculation, where a word is four bytes.

unshrink.c version 1.22 19 Mar 2008
NOTE: This code may or may not infringe on the so-called "Welch
patent" owned by Unisys. (From reading the patent, it appears
that a pure LZW decompressor is *not* covered, but this claim has
not been tested in court, and Unisys is reported to believe other-
wise.) It is therefore the responsibility of the user to acquire
whatever license(s) may be required for legal use of this code.
THE INFO-ZIP GROUP DISCLAIMS ALL LIABILITY FOR USE OF THIS CODE
IN VIOLATION OF APPLICABLE PATENT LAW.
Shrinking is basically a dynamic LZW algorithm with allowed code sizes of
up to 13 bits; in addition, there is provision for partial clearing of
leaf nodes. PKWARE uses the special code 256 (decimal) to indicate a
change in code size or a partial clear of the code tree: 256,1 for the
former and 256,2 for the latter. [Note that partial clearing can "orphan"
nodes: the parent-to-be can be cleared before its new child is added,
but the child is added anyway (as an orphan, as though the parent still
existed). When the tree fills up to the point where the parent node is
reused, the orphan is effectively "adopted." Versions prior to 1.05 were
affected more due to greater use of pointers (to children and siblings
as well as parents).]
This replacement version of unshrink.c was written from scratch. It is
based only on the algorithms described in Mark Nelson's _The Data Compres-
sion Book_ and in Terry Welch's original paper in the June 1984 issue of
IEEE _Computer_; no existing source code, including any in Nelson's book,
was used.
Memory requirements have been reduced in this version and are now no more
than the original Sam Smith code. This is still larger than any of the
other algorithms: at a minimum, 8K+8K+16K (stack+values+parents) assuming
16-bit short ints, and this does not even include the output buffer (the
other algorithms leave the uncompressed data in the work area, typically
called slide[]). For machines with a 64KB data space this is a problem,
particularly when text conversion is required and line endings have more
than one character. UnZip's solution is to use two roughly equal halves
of outbuf for the ASCII conversion in such a case; the "unshrink" argument
to flush() signals that this is the case.
For large-memory machines, a second outbuf is allocated for translations,
but only if unshrinking and only if translations are required.

| to make the action of the code less obscure.
|----------------------------------------------------------------
| UnZip notes: 24 May 92 ("v1.4"):
#include "libc/runtime/runtime.h"
#include "libc/runtime/runtime.h"
| 1. #include "third_party/unzip/unzip.h" for prototypes (24 May 92)
| 2. changed ch to type char (24 May 92)
| 3. added an ifdef to avoid Borland warnings (24 May 92)
| 4. included Rich Wales' mksargs() routine (for MS-DOS, maybe
| OS/2? NT?) (4 Dec 93)
| 5. added alternate-variable string envstr2 (21 Apr 94)
| 6. added support for quoted arguments (6 Jul 96)

* uses the infrastructure that is already in place in filedate.c, it is
* smaller. With this function, echoff() and echon() are not needed.
*
* For the MAC, a non-echo macgetch() function is defined in the MacOS
* specific sources which uses the event handling mechanism of the
* desktop window manager to get a character from the keyboard.
*
* For the other systems in this section, a non-echo getch() function
* is either contained the C runtime library (conio package), or getch()
* is defined as an alias for a similar system specific RTL function.

cosmopolitan/third_party/unzip/unix/Packaging/README | Solaris packaging
-----------------
To generate a Solaris package for Info-ZIP UnZip utilities,
first see the top level INSTALL and README files. Do a
"make solaris", which will automatically build two Solaris
installable package files for the package, IZunzip.
IZunzip -- Solaris installable package in directory format.
IZunzip_$(arch).pkg -- Solaris installable package in "stream" format.
Where: $(arch) := system architecture, currently i386, sparc, or ppc.
(use "uname -p" to determine)
The ".pkg" file is a single file datastream that can be compressed
and/or ftp'd. This is the recommended form, because all required
files are resident in the archive, and it is easily distributed.
To install, simply:
1) copy the package to the target system's /tmp directory.
2) login or su to root
3) pkgadd -d /tmp/IZunzip_$(arch).pkg
4) add /opt/Info-ZIP/IZunzip/bin to PATH
5) add /opt/Info-ZIP/IZunzip/man to MANPATH
This works for both SPARC and x86.
Ongoing maintenance:
Keep the files, "prototype" and "pkginfo.in" up to date.
Observe variable substitutions made by "Makefile".
See manpages for pkginfo(1), pkginfo(4), pkgmk(1), pkgproto(1)
Variations:
If you wish the base directory to be set to something other than
/opt/Info-ZIP, change the setting BASEDIR in pkginfo.in and
re-run the make.
