<p><code>git lfs prune</code> <a href="#OPTIONS" title="OPTIONS" data-bare-link="true">options</a></p> |
|
|
|
<h2 id="DESCRIPTION">DESCRIPTION</h2> |
|
|
|
<p>Deletes local copies of LFS files which are old, thus freeing up disk space. |
|
Prune operates by enumerating all the locally stored objects, and then deleting |
|
any which are not referenced by at least ONE of the following:</p> |
|
|
|
<ul> |
|
<li>the current checkout</li> |
|
<li>all existing stashes</li> |
|
<li>a 'recent branch'; see <a href="#RECENT-FILES" title="RECENT FILES" data-bare-link="true">RECENT FILES</a></li> |
|
<li>a 'recent commit' on the current branch or recent branches; see <a href="#RECENT-FILES" title="RECENT FILES" data-bare-link="true">RECENT FILES</a></li> |
|
<li>a commit which has not been pushed; see <a href="#UNPUSHED-LFS-FILES" title="UNPUSHED LFS FILES" data-bare-link="true">UNPUSHED LFS FILES</a></li> |
|
<li>any other worktree checkouts; see <span class="man-ref">git-worktree<span class="s">(1)</span></span></li> |
|
</ul> |
|
|
|
|
|
<p>In general terms, prune will delete files you're not currently using and which |
|
are not 'recent', so long as they've been pushed i.e. the local copy is not the |
|
only one.</p> |
|
|
|
<p>The reflog is not considered, only commits. Therefore LFS objects that are |
|
only referenced by orphaned commits are always deleted.</p> |
|
|
|
<p>Note: you should not run <code>git lfs prune</code> if you have different repositories |
|
sharing the same custom storage directory; see <span class="man-ref">git-lfs-config<span class="s">(1)</span></span> for more |
|
details about <code>lfs.storage</code> option.</p> |
|
|
|
<h2 id="OPTIONS">OPTIONS</h2> |
|
|
|
<ul> |
|
<li><p><code>--dry-run</code> <code>-d</code> |
|
Don't actually delete anything, just report on what would have been done</p></li> |
|
<li><p><code>--force</code> <code>-f</code> |
|
Prune all objects except unpushed objects, including objects required for |
|
currently checked out refs. Implies <code>--recent</code>.</p></li> |
|
<li><p><code>--recent</code> |
|
Prune even objects that would normally be preserved by the configuration |
|
options specified below in <a href="#RECENT-FILES" title="RECENT FILES" data-bare-link="true">RECENT FILES</a>.</p></li> |
|
<li><p><code>--verify-remote</code> <code>-c</code> |
|
Contact the remote and check that copies of the files we would delete |
|
definitely exist before deleting. See <a href="#VERIFY-REMOTE" title="VERIFY REMOTE" data-bare-link="true">VERIFY REMOTE</a>.</p></li> |
|
<li><p><code>--no-verify-remote</code> |
|
Disables remote verification if lfs.pruneverifyremotealways was enabled in |
|
settings. See <a href="#VERIFY-REMOTE" title="VERIFY REMOTE" data-bare-link="true">VERIFY REMOTE</a>.</p></li> |
|
<li><p><code>--verbose</code> <code>-v</code> |
|
Report the full detail of what is/would be deleted.</p></li> |
|
</ul> |
|
|
|
|
|
<h2 id="RECENT-FILES">RECENT FILES</h2> |
|
|
|
<p>Prune won't delete LFS files referenced by 'recent' commits, in case you want |
|
to use them again without having to download. The definition of 'recent' is |
|
derived from the one used by <span class="man-ref">git-lfs-fetch<span class="s">(1)</span></span> to download recent objects with |
|
the <code>--recent</code> option, with an offset of a number of days (default 3) to ensure |
|
that we always keep files you download for a few days.</p> |
|
|
|
<p>Here are the <span class="man-ref">git-config<span class="s">(1)</span></span> settings that control this behaviour:</p> |
|
|
|
<ul> |
|
<li><p><code>lfs.pruneoffsetdays</code> <br /> |
|
The number of extra days added to the fetch recent settings when using them |
|
to decide when to prune. So for a reference to be considered old enough to |
|
prune, it has to be this many days older than the oldest reference that would |
|
be downloaded via <code>git lfs fetch --recent</code>. Only used if the relevant |
|
fetch recent 'days' setting is non-zero. Default 3 days.</p></li> |
|
<li><p><code>lfs.fetchrecentrefsdays</code> <br /> |
|
<code>lfs.fetchrecentremoterefs</code> <br /> |
|
<code>lfs.fetchrecentcommitsdays</code> <br /> |
|
These have the same meaning as <span class="man-ref">git-lfs-fetch<span class="s">(1)</span></span> with the <code>--recent</code> option, |
|
they are used as a base for the offset above. Anything which falls outside |
|
of this offsetted window is considered old enough to prune. If a day value is |
|
zero, that condition is not used at all to retain objects and they will be |
|
pruned.</p></li> |
|
</ul> |
|
|
|
|
|
<h2 id="UNPUSHED-LFS-FILES">UNPUSHED LFS FILES</h2> |
|
|
|
<p>When the only copy of an LFS file is local, and it is still reachable from any |
|
reference, that file can never be pruned, regardless of how old it is.</p> |
|
|
|
<p>To determine whether an LFS file has been pushed, we check the difference |
|
between local refs and remote refs; where the local ref is ahead, any LFS files |
|
referenced in those commits is unpushed and will not be deleted. This works |
|
because the LFS pre-push hook always ensures that LFS files are pushed before |
|
the remote branch is updated.</p> |
|
|
|
<p>See <a href="#DEFAULT-REMOTE" title="DEFAULT REMOTE" data-bare-link="true">DEFAULT REMOTE</a>, for which remote is considered 'pushed' for pruning |
|
purposes.</p> |
|
|
|
<h2 id="VERIFY-REMOTE">VERIFY REMOTE</h2> |
|
|
|
<p>The <code>--verify-remote</code> option calls the remote to ensure that any LFS files to be |
|
deleted have copies on the remote before actually deleting them.</p> |
|
|
|
<p>Usually the check performed by <a href="#UNPUSHED-LFS-FILES" title="UNPUSHED LFS FILES" data-bare-link="true">UNPUSHED LFS FILES</a> is enough to determine that |
|
files have been pushed, but if you want to be extra sure at the expense of extra |
|
overhead you can make prune actually call the remote API and verify the |
|
presence of the files you're about to delete locally. See <a href="#DEFAULT-REMOTE" title="DEFAULT REMOTE" data-bare-link="true">DEFAULT REMOTE</a> for |
|
which remote is checked.</p> |
|
|
|
<p>You can make this behaviour the default by setting <code>lfs.pruneverifyremotealways</code> |
|
to true.</p> |
|
|
|
<p>In addition to the overhead of calling the remote, using this option also |
|
requires prune to distinguish between totally unreachable files (e.g. those that |
|
were added to the index but never committed, or referenced only by orphaned |
|
commits), and files which are still referenced, but by commits which are |
|
prunable. This makes the prune process take longer.</p> |
|
|
|
<h2 id="DEFAULT-REMOTE">DEFAULT REMOTE</h2> |
|
|
|
<p>When identifying <a href="#UNPUSHED-LFS-FILES" title="UNPUSHED LFS FILES" data-bare-link="true">UNPUSHED LFS FILES</a> and performing <a href="#VERIFY-REMOTE" title="VERIFY REMOTE" data-bare-link="true">VERIFY REMOTE</a>, a single |
|
remote, 'origin', is normally used as the reference. This one remote is |
|
considered canonical; even if you use multiple remotes, you probably want to |
|
retain your local copies until they've made it to that remote. 'origin' is used |
|
by default because that will usually be a main central repo, or your fork of |
|
it - in both cases that's a valid remote backup of your work. If origin doesn't |
|
exist then by default nothing will be pruned because everything is treated as |
|
'unpushed'.</p> |
|
|
|
<p>You can alter the remote via git config: <code>lfs.pruneremotetocheck</code>. Set this |
|
to a different remote name to check that one instead of 'origin'.</p> |
