<h2 id="_description">DESCRIPTION</h2>
<div class="sectionbody">
<div class="paragraph"><p>This command manages the information recorded in the reflogs.</p></div>
<div class="paragraph"><p>Reference logs, or "reflogs", record when the tips of branches and
other references were updated in the local repository. Reflogs are
useful in various Git commands, to specify the old value of a
reference. For example, <code>HEAD@{2}</code> means "where HEAD used to be two
moves ago", <code>master@{one.week.ago}</code> means "where master used to point
to one week ago in this local repository", and so on. See
<a href="gitrevisions.html">gitrevisions(7)</a> for more details.</p></div>
<div class="paragraph"><p>The command takes various subcommands, and different options
depending on the subcommand:</p></div>
<div class="paragraph"><p>The "show" subcommand (which is also the default, in the absence of
any subcommands) shows the log of the reference provided in the
command-line (or <code>HEAD</code>, by default). The reflog covers all recent
actions, and in addition the <code>HEAD</code> reflog records branch switching.
<code>git reflog show</code> is an alias for <code>git log -g --abbrev-commit
--pretty=oneline</code>; see <a href="git-log.html">git-log(1)</a> for more information.</p></div>
<div class="paragraph"><p>The "expire" subcommand prunes older reflog entries. Entries older
than <code>expire</code> time, or entries older than <code>expire-unreachable</code> time
and not reachable from the current tip, are removed from the reflog.
This is typically not used directly by end users&#8201;&#8212;&#8201;instead, see
<a href="git-gc.html">git-gc(1)</a>.</p></div>
<div class="paragraph"><p>The "delete" subcommand deletes single entries from the reflog. Its
argument must be an <em>exact</em> entry (e.g. "<code>git reflog delete
master@{2}</code>"). This subcommand is also typically not used directly by
end users.</p></div>
<div class="paragraph"><p>The "exists" subcommand checks whether a ref has a reflog.  It exits
with zero status if the reflog exists, and non-zero status if it does
not.</p></div>
</div>
</div>

<div class="sect2">

<dt class="hdlist1">
--single-worktree
</dt>
<dd>
<p>
        By default when <code>--all</code> is specified, reflogs from all working
        trees are processed. This option limits the processing to reflogs
        from the current working tree only.

<p>
        Prune entries older than the specified time. If this option is
        not specified, the expiration time is taken from the
        configuration setting <code>gc.reflogExpire</code>, which in turn
        defaults to 90 days. <code>--expire=all</code> prunes entries regardless
        of their age; <code>--expire=never</code> turns off pruning of reachable
        entries (but see <code>--expire-unreachable</code>).

<p>
        Prune entries older than <code>&lt;time&gt;</code> that are not reachable from
        the current tip of the branch. If this option is not
        specified, the expiration time is taken from the configuration
        setting <code>gc.reflogExpireUnreachable</code>, which in turn defaults
        to 30 days. <code>--expire-unreachable=all</code> prunes unreachable
        entries regardless of their age; <code>--expire-unreachable=never</code>
        turns off early pruning of unreachable entries (but see
        <code>--expire</code>).
</p>
</dd>
<dt class="hdlist1">
--updateref
</dt>
<dd>
<p>
        Update the reference to the value of the top reflog entry (i.e.
        &lt;ref&gt;@{0}) if the previous top entry was pruned.  (This
        option is ignored for symbolic references.)
</p>
</dd>
<dt class="hdlist1">
--rewrite
</dt>
<dd>
<p>
        If a reflog entry&#8217;s predecessor is pruned, adjust its "old"
        SHA-1 to be equal to the "new" SHA-1 field of the entry that
        now precedes it.
</p>
</dd>
<dt class="hdlist1">
--stale-fix
</dt>
<dd>
<p>
        Prune any reflog entries that point to "broken commits". A
        broken commit is a commit that is not reachable from any of
        the reference tips and that refers, directly or indirectly, to
        a missing commit, tree, or blob object.

<div class="paragraph"><p>This computation involves traversing all the reachable objects, i.e. it
