</div>
<div class="sect1">
<h2 id="_description">DESCRIPTION</h2>
<div class="sectionbody">
<div class="paragraph">
<p>Reads a tag&#8217;s contents on standard input and creates a tag object. The
output is the new tag&#8217;s &lt;object&gt; identifier.</p>
</div>
<div class="paragraph">
<p>This command is mostly equivalent to <a href="git-hash-object.html">git-hash-object(1)</a>
invoked with <code>-t</code> <code>tag</code> <code>-w</code> <code>--stdin</code>. I.e. both of these will create and
write a tag found in <code>my-tag</code>:</p>
</div>
<div class="literalblock">
<div class="content">
<pre>git mktag &lt;my-tag
git hash-object -t tag -w --stdin &lt;my-tag</pre>
</div>
</div>
<div class="paragraph">
<p>The difference is that mktag will die before writing the tag if the
tag doesn&#8217;t pass a <a href="git-fsck.html">git-fsck(1)</a> check.</p>
</div>
<div class="paragraph">
<p>The "fsck" check done by mktag is stricter than what <a href="git-fsck.html">git-fsck(1)</a>
would run by default in that all <code>fsck.</code><em>&lt;msg-id&gt;</em> messages are promoted
from warnings to errors (so e.g. a missing "tagger" line is an error).</p>
</div>
<div class="paragraph">
<p>Extra headers in the object are also an error under mktag, but ignored
by <a href="git-fsck.html">git-fsck(1)</a>. This extra check can be turned off by setting
the appropriate <code>fsck.</code><em>&lt;msg-id&gt;</em> variable:</p>
</div>
<div class="literalblock">
<div class="content">
<pre>git -c fsck.extraHeaderEntry=ignore mktag &lt;my-tag-with-headers</pre>

<h2 id="_options">OPTIONS</h2>
<div class="sectionbody">
<div class="dlist">
<dl>
<dt class="hdlist1">--strict</dt>
<dd>
<p>By default mktag turns on the equivalent of
<a href="git-fsck.html">git-fsck(1)</a> <code>--strict</code> mode. Use <code>--no-strict</code> to
disable it.</p>
</dd>
</dl>

<h2 id="_tag_format">Tag Format</h2>
<div class="sectionbody">
<div class="paragraph">
<p>A tag signature file, to be fed to this command&#8217;s standard input,
has a very simple fixed format: four lines of</p>

</div>
</div>
<div class="paragraph">
<p>followed by some <em>optional</em> free-form message (some tags created
by older Git may not have a <code>tagger</code> line).  The message, when it
exists, is separated by a blank line from the header.  The
message part may contain a signature that Git itself doesn&#8217;t
care about, but that can be verified with gpg.</p>
