 git-reflog(1) Manual Page

 <h2>NAME</h2>
 <div class="sectionbody">
 <p>git-reflog -
  Manage reflog information
 </p>
 </div>
 </div>
 <h2>SYNOPSIS</h2>
 <div class="sectionbody">
 <p><em>git reflog</em> &lt;subcommand&gt; &lt;options&gt;</p>
 </div>
 <h2>DESCRIPTION</h2>
 <div class="sectionbody">
 <p>The command takes various subcommands, and different options
 depending on the subcommand:</p>
 <div class="verseblock">
 <div class="content">git reflog expire [--dry-run] [--stale-fix] [--verbose]
  [--expire=&lt;time&gt;] [--expire-unreachable=&lt;time&gt;] [--all] &lt;refs&gt;&#8230;</div></div>
 <p>git reflog [show] [log-options]</p>
 <p>Reflog is a mechanism to record when the tip of branches are
 updated. This command is to manage the information recorded in it.</p>
 <p>The subcommand "expire" is used to prune older reflog entries.
 Entries older than <tt>expire</tt> time, or entries older than
 <tt>expire-unreachable</tt> time and are not reachable from the current
 tip, are removed from the reflog. This is typically not used
 directly by the end users &#8212; instead, see <a href="git-gc.html">git-gc(1)</a>.</p>
 <p>The subcommand "show" (which is also the default, in the absence of any
 subcommands) will take all the normal log options, and show the log of
 <tt>HEAD</tt>, which will cover all recent actions, including branch switches.
 It is basically an alias for <em>git log -g --abbrev-commit
 --pretty=oneline</em>, see <a href="git-log.html">git-log(1)</a>.</p>
 </div>
 <h2>OPTIONS</h2>
 <div class="sectionbody">
 <dl>
 <dt>
 --stale-fix
 </dt>
 <dd>
 <p>
  This revamps the logic &#8212; the definition of "broken commit"
  becomes: a commit that is not reachable from any of the refs and
  there is a missing object among the commit, tree, or blob
  objects reachable from it that is not reachable from any of the
  refs.
 </p>
 <p>This computation involves traversing all the reachable objects, i.e. it
 has the same cost as <em>git prune</em>. Fortunately, once this is run, we
 should not have to ever worry about missing objects, because the current
 prune and pack-objects know about reflogs and protect objects referred by
 them.</p>
 </dd>
 <dt>
 --expire=&lt;time&gt;
 </dt>
 <dd>
 <p>
  Entries older than this time are pruned. Without the
  option it is taken from configuration <tt>gc.reflogExpire</tt>,
  which in turn defaults to 90 days.
 </p>
 </dd>
 <dt>
 --expire-unreachable=&lt;time&gt;
 </dt>
 <dd>
 <p>
  Entries older than this time and are not reachable from
  the current tip of the branch are pruned. Without the
  option it is taken from configuration
  <tt>gc.reflogExpireUnreachable</tt>, which in turn defaults to
  30 days.
 </p>
 </dd>
 <dt>
 --all
 </dt>
 <dd>
 <p>
  Instead of listing &lt;refs&gt; explicitly, prune all refs.
 </p>
 </dd>
 <dt>
 --verbose
 </dt>
 <dd>
 <p>
  Print extra information on screen.
