 467 <div class="sectionbody">
 468 <div class="paragraph">
 469 <p>This command manages the information recorded in the reflogs.</p>
 470 </div>
 471 <div class="paragraph">
 472 <p>Reference logs, or "reflogs", record when the tips of branches and
 473 other references were updated in the local repository. Reflogs are
 474 useful in various Git commands, to specify the old value of a
 475 reference. For example, <code>HEAD@{2}</code> means "where HEAD used to be two
 476 moves ago", <code>master@{one.week.ago}</code> means "where master used to point
 477 to one week ago in this local repository", and so on. See
 478 <a href="gitrevisions.html">gitrevisions(7)</a> for more details.</p>
 479 </div>
 480 <div class="paragraph">
 481 <p>The command takes various subcommands, and different options
 482 depending on the subcommand:</p>
 483 </div>
 484 <div class="paragraph">
 485 <p>The "show" subcommand (which is also the default, in the absence of
 486 any subcommands) shows the log of the reference provided in the
 487 command-line (or <code>HEAD</code>, by default). The reflog covers all recent
 488 actions, and in addition the <code>HEAD</code> reflog records branch switching.
 489 <code>git reflog show</code> is an alias for <code>git log -g --abbrev-commit
 490 --pretty=oneline</code>; see <a href="git-log.html">git-log(1)</a> for more information.</p>
 491 </div>
 492 <div class="paragraph">
 493 <p>The "list" subcommand lists all refs which have a corresponding reflog.</p>
 494 </div>
 495 <div class="paragraph">
 496 <p>The "expire" subcommand prunes older reflog entries. Entries older
 497 than <code>expire</code> time, or entries older than <code>expire-unreachable</code> time
 498 and not reachable from the current tip, are removed from the reflog.
 499 This is typically not used directly by end users&#8201;&#8212;&#8201;instead, see
 500 <a href="git-gc.html">git-gc(1)</a>.</p>
 501 </div>
 502 <div class="paragraph">
 503 <p>The "delete" subcommand deletes single entries from the reflog. Its
 504 argument must be an <em>exact</em> entry (e.g. "<code>git reflog delete
 505 master@{2}</code>"). This subcommand is also typically not used directly by
 506 end users.</p>
 507 </div>
 508 <div class="paragraph">
 509 <p>The "exists" subcommand checks whether a ref has a reflog.  It exits
 510 with zero status if the reflog exists, and non-zero status if it does
 511 not.</p>

 531 </dd>
 532 <dt class="hdlist1">--single-worktree</dt>
 533 <dd>
 534 <p>By default when <code>--all</code> is specified, reflogs from all working
 535 trees are processed. This option limits the processing to reflogs
 536 from the current working tree only.</p>
 537 </dd>
 538 <dt class="hdlist1">--expire=&lt;time&gt;</dt>
 539 <dd>
 540 <p>Prune entries older than the specified time. If this option is
 541 not specified, the expiration time is taken from the
 542 configuration setting <code>gc.reflogExpire</code>, which in turn
 543 defaults to 90 days. <code>--expire=all</code> prunes entries regardless
 544 of their age; <code>--expire=never</code> turns off pruning of reachable
 545 entries (but see <code>--expire-unreachable</code>).</p>
 546 </dd>
 547 <dt class="hdlist1">--expire-unreachable=&lt;time&gt;</dt>
 548 <dd>
 549 <p>Prune entries older than <code>&lt;time&gt;</code> that are not reachable from
 550 the current tip of the branch. If this option is not
 551 specified, the expiration time is taken from the configuration
 552 setting <code>gc.reflogExpireUnreachable</code>, which in turn defaults
 553 to 30 days. <code>--expire-unreachable=all</code> prunes unreachable
 554 entries regardless of their age; <code>--expire-unreachable=never</code>
 555 turns off early pruning of unreachable entries (but see
 556 <code>--expire</code>).</p>
 557 </dd>
 558 <dt class="hdlist1">--updateref</dt>
 559 <dd>
 560 <p>Update the reference to the value of the top reflog entry (i.e.
 561 &lt;ref&gt;@{0}) if the previous top entry was pruned.  (This
 562 option is ignored for symbolic references.)</p>
 563 </dd>
 564 <dt class="hdlist1">--rewrite</dt>
 565 <dd>
 566 <p>If a reflog entry&#8217;s predecessor is pruned, adjust its "old"
 567 SHA-1 to be equal to the "new" SHA-1 field of the entry that
 568 now precedes it.</p>
 569 </dd>
 570 <dt class="hdlist1">--stale-fix</dt>
 571 <dd>
 572 <p>Prune any reflog entries that point to "broken commits". A
 573 broken commit is a commit that is not reachable from any of
 574 the reference tips and that refers, directly or indirectly, to
 575 a missing commit, tree, or blob object.</p>
 576 <div class="paragraph">
 577 <p>This computation involves traversing all the reachable objects, i.e. it
 578 has the same cost as <em>git prune</em>.  It is primarily intended to fix
 579 corruption caused by garbage collecting using older versions of Git,
 580 which didn&#8217;t protect objects referred to by reflogs.</p>
