277<h2>DESCRIPTION</h2>
278<div class="sectionbody">
Junio C Hamanod3339982007-02-09 08:38:48[diff] [blame]279<p>The command takes various subcommands, and different options
280depending on the subcommand:</p>

284<p>git reflog [show] [log-options]</p>
Junio C Hamano74640642006-12-27 10:59:55[diff] [blame]285<p>Reflog is a mechanism to record when the tip of branches are
286updated. This command is to manage the information recorded in it.</p>
287<p>The subcommand "expire" is used to prune older reflog entries.
288Entries older than <tt>expire</tt> time, or entries older than
289<tt>expire-unreachable</tt> time and are not reachable from the current
290tip, are removed from the reflog. This is typically not used
291directly by the end users &#8212; instead, see <a href="git-gc.html">git-gc(1)</a>.</p>
Junio C Hamanoa6387422007-08-25 03:54:27[diff] [blame]292<p>The subcommand "show" (which is also the default, in the absence of any
Junio C Hamanod3339982007-02-09 08:38:48[diff] [blame]293subcommands) will take all the normal log options, and show the log of
Junio C Hamanoe52cf782007-08-19 19:15:52[diff] [blame]294<tt>HEAD</tt>, which will cover all recent actions, including branch switches.
295It is basically an alias for <em>git log -g --abbrev-commit
Junio C Hamanod3339982007-02-09 08:38:48[diff] [blame]296--pretty=oneline</em>, see <a href="git-log.html">git-log(1)</a>.</p>

305<p>
306 This revamps the logic &#8212; the definition of "broken commit"
307 becomes: a commit that is not reachable from any of the refs and
308 there is a missing object among the commit, tree, or blob
309 objects reachable from it that is not reachable from any of the
310 refs.
311</p>
312<p>This computation involves traversing all the reachable objects, i.e. it
313has the same cost as <em>git prune</em>. Fortunately, once this is run, we
314should not have to ever worry about missing objects, because the current
315prune and pack-objects know about reflogs and protect objects referred by
316them.</p>

323 Entries older than this time are pruned. Without the
