| @REM Do not use "echo off" to not affect any child calls. | |
| @REM The goal of this script is to simplify launching `ssh-pageant` at | |
| @REM logon, typically by dropping a shortcut into the Startup folder, so | |
| @REM that Pageant (the PuTTY authentication agent) will always be | |
| @REM accessible. No attempt is made to load SSH keys, since this is | |
| @REM normally handled directly by Pageant, and no interactive shell | |
| @REM will be launched. | |
| @REM | |
| @REM The `ssh-pageant` utility is launched with the `-r` (reuse socket) | |
| @REM option, to ensure that only a single running incarnation (per user) | |
| @REM will be required... instead of launching a separate process for | |
| @REM every interactive Git Bash session. A side effect of this selection | |
| @REM is that the SSH_AUTH_SOCK environment variable *must* be set prior | |
| @REM to running this script, with the value specifying a unix-style socket | |
| @REM path, and needs to be consistent for all git-related processes. The | |
| @REM easiest way to do this is to set a persistent USER environment | |
| @REM variable, which (under Windows 7) can be done via Control Panel | |
| @REM under System / Advanced System Settings. A typical value would look | |
| @REM similar to: | |
| @REM | |
| @REM SSH_AUTH_SOCK=/tmp/.ssh-pageant-USERNAME | |
| @REM | |
| @REM Enable extensions, the `verify` call is a trick from the setlocal help | |
| @VERIFY other 2>nul | |
| @SETLOCAL EnableDelayedExpansion | |
| @IF ERRORLEVEL 1 ( | |
| @ECHO Unable to enable extensions | |
| @GOTO failure | |
