<div class="sectionbody"> | |
<div class="paragraph"><p>The command takes various subcommands, and different options | |
depending on the subcommand:</p></div> | |
<div class="verseblock"> | |
<pre class="content"><em>git reflog</em> [<em>show</em>] [log-options] [<ref>] | |

<em>git reflog exists</em> <ref></pre> | |
<div class="attribution"> | |
</div></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>This command manages the information recorded in the reflogs.</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 — 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 class="dlist"><dl> | |
<dt class="hdlist1"> | |
--all | |
</dt> | |

Process the reflogs of all references. | |

</dd> | |
<dt class="hdlist1"> | |
--expire=<time> | |
</dt> | |
<dd> | |
<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> | |
</dd> | |
<dt class="hdlist1"> | |
--expire-unreachable=<time> | |
</dt> | |
<dd> | |
<p> | |
Prune entries older than <code><time></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. | |
<ref>@{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’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. | |
</p> | |
<div class="paragraph"><p>This computation involves traversing all the reachable objects, i.e. it | |
has the same cost as <em>git prune</em>. It is primarily intended to fix | |
corruption caused by garbage collecting using older versions of Git, | |
which didn’t protect objects referred to by reflogs.</p></div> | |
