+</h1>
+<h2>NAME</h2>
+<div class="sectionbody">
+<p>git-show-ref -
+ List references in a local repository
+</p>
+</div>
+</div>
+<h2>SYNOPSIS</h2>
+<div class="sectionbody">
+<div class="verseblock">
+<div class="content"><em>git-show-ref</em> [-q|--quiet] [--verify] [-h|--head] [-d|--dereference]
+ [-s|--hash] [--abbrev] [--tags] [--heads] [--] <pattern>…</div></div>
+</div>
+<h2>DESCRIPTION</h2>
+<div class="sectionbody">
+<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>
+<p>Use of this utility is encouraged in favor of directly accessing files under
+in the <tt>.git</tt> directory.</p>
+</div>
+<h2>OPTIONS</h2>
+<div class="sectionbody">
+<dl>
+<dt>
+-h, --head
+</dt>
+<dd>
+<p>
+ Show the HEAD reference.
+</p>
+</dd>
+<dt>
+--tags, --heads
+</dt>
+<dd>
+<p>
+ Limit to only "refs/heads" and "refs/tags", respectively. These
+ options are not mutually exclusive; when given both, references stored
+ in "refs/heads" and "refs/tags" are displayed.
+</p>
+</dd>
+<dt>
+-d, --dereference
+</dt>
+<dd>
+<p>
+ Dereference tags into object IDs as well. They will be shown with "^{}"
+ appended.
+</p>
+</dd>
+<dt>
+-s, --hash
+</dt>
+<dd>
+<p>
+ Only show the SHA1 hash, not the reference name. When also using
+ --dereference the dereferenced tag will still be shown after the SHA1.
+</p>
+</dd>
+<dt>
+--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 <em>--quiet</em> was not specified.
+</p>
+</dd>
+<dt>
+--abbrev, --abbrev=len
+</dt>
+<dd>
+<p>
+ Abbreviate the object name. When using <tt>--hash</tt>, you do
+ not have to say <tt>--hash --abbrev</tt>; <tt>--hash=len</tt> would do.
+</p>
+</dd>
+<dt>
+-q, --quiet
+</dt>
+<dd>
+<p>
+ Do not print any results to stdout. When combined with <em>--verify</em> this
+ can be used to silently check if a reference exists.
+</p>
+</dd>
+<dt>
+<pattern>
+</dt>
+<dd>
+<p>
+ Show references matching one or more patterns.
+</p>
+</dd>
+</dl>
+</div>
+<h2>OUTPUT</h2>
+<div class="sectionbody">
+<p>The output is in the format: <em><SHA-1 ID></em> <em><space></em> <em><reference name></em>.</p>
+<div class="listingblock">

+<p>When using --hash (and not --dereference) the output format is: <em><SHA-1 ID></em></p>

+03adf42c988195b50e1a1935ba5fcbc39b2b029b
+...</tt></pre>
+</div></div>
+</div>
+<h2>EXAMPLE</h2>
+<div class="sectionbody">
+<p>To show all references called "master", whether tags or heads or anything
+else, and regardless of how deep in the reference naming hierarchy they are,
+use:</p>
+<div class="listingblock">
+<div class="content">
+<pre><tt> git show-ref master</tt></pre>
+</div></div>
+<p>This will show "refs/heads/master" but also "refs/remote/other-repo/master",
+if such references exists.</p>
+<p>When using the <em>--verify</em> flag, the command requires an exact path:</p>
+<div class="listingblock">
+<div class="content">
+<pre><tt> git show-ref --verify refs/heads/master</tt></pre>
+</div></div>
+<p>will only match the exact branch called "master".</p>
+<p>If nothing matches, <a href="git-show-ref.html">git-show-ref(1)</a> will return an error code of 1,
+and in the case of verification, it will show an error message.</p>
+<p>For scripting, you can ask it to be quiet with the "--quiet" flag, which
+allows you to do things like</p>
+<div class="listingblock">
+<div class="content">
+<pre><tt> git-show-ref --quiet --verify -- "refs/heads/$headname" ||
+ echo "$headname is not a valid branch"</tt></pre>
+</div></div>
+<p>to check whether a particular branch exists or not (notice how we don't
+actually want to show any results, and we want to use the full refname for it
+in order to not trigger the problem with ambiguous partial matches).</p>
+<p>To show only tags, or only proper branch heads, use "--tags" and/or "--heads"
+respectively (using both means that it shows tags and heads, but not other
+random references under the refs/ subdirectory).</p>
+<p>To do automatic tag object dereferencing, use the "-d" or "--dereference"
+flag, so you can do</p>
+<div class="listingblock">
+<div class="content">
+<pre><tt> git show-ref --tags --dereference</tt></pre>
+</div></div>
+<p>to get a listing of all tags together with what they dereference.</p>
+</div>
