<h2 id="_description">DESCRIPTION</h2>
<div class="sectionbody">
<div class="paragraph">
<p>Displays references available in a local repository along with the associated
commit IDs. Results can be filtered using a pattern and tags can be
dereferenced into object IDs. Additionally, it can be used to test whether a
particular ref exists.</p>
</div>
<div class="paragraph">
<p>By default, shows the tags, heads, and remote refs.</p>
</div>
<div class="paragraph">
<p>The <code>--exclude-existing</code> form is a filter that does the inverse. It reads
refs from stdin, one ref per line, and shows those that don&#8217;t exist in
the local repository.</p>
</div>
<div class="paragraph">
<p>The <code>--exists</code> form can be used to check for the existence of a single
references. This form does not verify whether the reference resolves to an
actual object.</p>
</div>
<div class="paragraph">
<p>Use of this utility is encouraged in favor of directly accessing files under
the .<code>git</code> directory.</p>
</div>
</div>
</div>
<div class="sect1">
<h2 id="_options">OPTIONS</h2>
<div class="sectionbody">
<div class="dlist">
<dl>
<dt class="hdlist1">--head</dt>
<dd>
<p>Show the HEAD reference, even if it would normally be filtered out.</p>
</dd>
<dt class="hdlist1">--branches</dt>
<dt class="hdlist1">--tags</dt>
<dd>
<p>Limit to local branches and local tags, respectively.  These options
are not mutually exclusive; when given both, references stored in
"refs/heads" and "refs/tags" are displayed.  Note that <code>--heads</code>
is a deprecated synonym for <code>--branches</code> and may be removed
in the future.</p>
</dd>
<dt class="hdlist1">-d</dt>
<dt class="hdlist1">--dereference</dt>
<dd>
<p>Dereference tags into object IDs as well. They will be shown with <code>^</code>{}
appended.</p>
</dd>
<dt class="hdlist1">-s</dt>
<dt class="hdlist1">--hash[=&lt;n&gt;]</dt>
<dd>
<p>Only show the OID, not the reference name. When combined with
<code>--dereference</code>, the dereferenced tag will still be shown after the OID.</p>
</dd>
<dt class="hdlist1">--verify</dt>
<dd>
<p>Enable stricter reference checking by requiring an exact ref path.
Aside from returning an error code of 1, it will also print an error
message if <code>--quiet</code> was not specified.</p>
</dd>
<dt class="hdlist1">--exists</dt>
<dd>
<p>Check whether the given reference exists. Returns an exit code of 0 if
it does, 2 if it is missing, and 1 in case looking up the reference
failed with an error other than the reference being missing.</p>
</dd>
<dt class="hdlist1">--abbrev[=&lt;n&gt;]</dt>
<dd>
<p>Abbreviate the object name.  When using <code>--hash</code>, you do
not have to say <code>--hash</code> <code>--abbrev</code>; <code>--hash=n</code> would do.</p>
</dd>
<dt class="hdlist1">-q</dt>
<dt class="hdlist1">--quiet</dt>
<dd>
<p>Do not print any results to stdout. Can be used with <code>--verify</code> to
silently check if a reference exists.</p>
</dd>
<dt class="hdlist1">--exclude-existing[=&lt;pattern&gt;]</dt>
<dd>
<p>Make <code>git</code> <code>show-ref</code> act as a filter that reads refs from stdin of the
form <code>^</code>(?:<em>&lt;anything&gt;</em>\s)?<em>&lt;refname&gt;</em>(?:\^{})?$
and performs the following actions on each:
(1) strip <code>^</code>{} at the end of line if any;
(2) ignore if pattern is provided and does not head-match refname;
(3) warn if refname is not a well-formed refname and skip;
(4) ignore if refname is a ref that exists in the local repository;
(5) otherwise output the line.</p>
</dd>
<dt class="hdlist1">&lt;pattern&gt;&#8230;&#8203;</dt>
<dd>
<p>Show references matching one or more patterns. Patterns are matched from
the end of the full name, and only complete parts are matched, e.g.
<em>master</em> matches <em>refs/heads/master</em>, <em>refs/remotes/origin/master</em>,
<em>refs/tags/jedi/master</em> but not <em>refs/heads/mymaster</em> or
<em>refs/remotes/master/jedi</em>.</p>
