 git-show-ref(1) Manual Page
 </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] [--] &lt;pattern&gt;&#8230;
 <em>git show-ref</em> --exclude-existing[=pattern]</div></div>
 </div>
 <h2 id="_description">DESCRIPTION</h2>
 <div class="sectionbody">
 <div class="para"><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="para"><p>The --exclude-existing form is a filter that does the inverse, it shows the
 refs from stdin that don't exist in the local repository.</p></div>
 <div class="para"><p>Use of this utility is encouraged in favor of directly accessing files under
 in the <tt>.git</tt> directory.</p></div>
 </div>
 <h2 id="_options">OPTIONS</h2>
 <div class="sectionbody">
 <div class="vlist"><dl>
 <dt>
 -h
 </dt>
 <dt>
 --head
 </dt>
 <dd>
 <p>
  Show the HEAD reference.
 </p>
 </dd>
 <dt>
 --tags
 </dt>
 <dt>
 --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
 </dt>
 <dt>
 --dereference
 </dt>
 <dd>
 <p>
  Dereference tags into object IDs as well. They will be shown with "^{}"
  appended.
 </p>
 </dd>
 <dt>
 -s
 </dt>
 <dt>
 --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
 </dt>
 <dt>
 --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
 </dt>
 <dt>
 --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>
 --exclude-existing
 </dt>
 <dt>
 --exclude-existing=pattern
 </dt>
 <dd>
 <p>
  Make <em>git-show-ref</em> act as a filter that reads refs from stdin of the
  form "<sup>(?:&lt;anything&gt;\s)?&lt;refname&gt;(?:\</sup>{})?$" and performs the
  following actions on each:
  (1) strip "^{}" 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>
 &lt;pattern&gt;&#8230;
 </dt>
 <dd>
 <p>
  Show references matching one or more patterns.
 </p>
 </dd>
 </dl></div>

 <h2 id="_example">EXAMPLE</h2>
 <div class="sectionbody">
 <div class="para"><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>
 <div class="listingblock">
 <div class="content">
 <pre><tt> git show-ref master</tt></pre>
 </div></div>
 <div class="para"><p>This will show "refs/heads/master" but also "refs/remote/other-repo/master",
 if such references exists.</p></div>
 <div class="para"><p>When using the <em>--verify</em> flag, the command requires an exact path:</p></div>
 <div class="listingblock">
 <div class="content">
 <pre><tt> git show-ref --verify refs/heads/master</tt></pre>
 </div></div>
 <div class="para"><p>will only match the exact branch called "master".</p></div>
 <div class="para"><p>If nothing matches, <em>git-show-ref</em> will return an error code of 1,
 and in the case of verification, it will show an error message.</p></div>
 <div class="para"><p>For scripting, you can ask it to be quiet with the "--quiet" flag, which
 allows you to do things like</p></div>
 <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>
 <div class="para"><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></div>
 <div class="para"><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></div>
 <div class="para"><p>To do automatic tag object dereferencing, use the "-d" or "--dereference"
 flag, so you can do</p></div>
 <div class="listingblock">
 <div class="content">
 <pre><tt> git show-ref --tags --dereference</tt></pre>

	<h2>SYNOPSIS</h2>
	<div class="sectionbody">
	<div class="verseblock">
	<div class="content"><em>git show-ref</em> [-q\|--quiet] [--verify] [-h\|--head] [-d\|--dereference]

	</div>
	<h2 id="_description">DESCRIPTION</h2>
	<div class="sectionbody">
	<div class="para"><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="para"><p>The --exclude-existing form is a filter that does the inverse, it shows the
	refs from stdin that don't exist in the local repository.</p></div>
	<div class="para"><p>Use of this utility is encouraged in favor of directly accessing files under
	in the <tt>.git</tt> directory.</p></div>
	</div>
	<h2 id="_options">OPTIONS</h2>
	<div class="sectionbody">
	<div class="vlist"><dl>
	<dt>
	-h
	</dt>
	<dt>
	--head
	</dt>
	<dd>
	<p>
	Show the HEAD reference.
	</p>
	</dd>
	<dt>
	--tags
	</dt>
	<dt>
	--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
	</dt>
	<dt>
	--dereference
	</dt>
	<dd>
	<p>
	Dereference tags into object IDs as well. They will be shown with "^{}"
	appended.
	</p>
	</dd>
	<dt>
	-s
	</dt>
	<dt>
	--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
	</dt>
	<dt>
	--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
	</dt>
	<dt>
	--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>
	--exclude-existing
	</dt>
	<dt>
	--exclude-existing=pattern
	</dt>
	<dd>
	<p>
	Make <em>git-show-ref</em> act as a filter that reads refs from stdin of the
	form "<sup>(?:<anything>\s)?<refname>(?:\</sup>{})?$" and performs the
	following actions on each:
	(1) strip "^{}" 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>
	<pattern>…
	</dt>
	<dd>
	<p>
	Show references matching one or more patterns.
	</p>
	</dd>
	</dl></div>

	</div></div>
	<div class="para"><p>This will show "refs/heads/master" but also "refs/remote/other-repo/master",

	<div class="para"><p>When using the <em>--verify</em> flag, the command requires an exact path:</p></div>

	<div class="para"><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></div>
	<div class="para"><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></div>
	<div class="para"><p>To do automatic tag object dereferencing, use the "-d" or "--dereference"
	flag, so you can do</p></div>
