<h2 id="_description">DESCRIPTION</h2>
<div class="sectionbody">
<div class="paragraph">
<p>Usually you would want to use <em>git push</em>, which is a
higher-level wrapper of this command, instead. See <a href="git-push.html">git-push(1)</a>.</p>
</div>
<div class="paragraph">
<p>Invokes <em>git-receive-pack</em> on a possibly remote repository, and
updates it from the current repository, sending named refs.</p>

<div class="sect1">
<h2 id="_options">OPTIONS</h2>
<div class="sectionbody">
<div class="dlist">
<dl>
<dt class="hdlist1">--receive-pack=&lt;git-receive-pack&gt;</dt>
<dd>
<p>Path to the <em>git-receive-pack</em> program on the remote
end.  Sometimes useful when pushing to a remote
repository over ssh, and you do not have the program in
a directory on the default $PATH.</p>
</dd>
<dt class="hdlist1">--exec=&lt;git-receive-pack&gt;</dt>
<dd>
<p>Same as --receive-pack=&lt;git-receive-pack&gt;.</p>
</dd>
<dt class="hdlist1">--all</dt>
<dd>
<p>Instead of explicitly specifying which refs to update,
update all heads that locally exist.</p>
</dd>
<dt class="hdlist1">--stdin</dt>
<dd>
<p>Take the list of refs from stdin, one per line. If there
are refs specified on the command line in addition to this
option, then the refs from stdin are processed after those
on the command line.</p>
<div class="paragraph">
<p>If <code>--stateless-rpc</code> is specified together with this option then
the list of refs must be in packet format (pkt-line). Each ref must
be in a separate packet, and the list must end with a flush packet.</p>
</div>
</dd>
<dt class="hdlist1">--dry-run</dt>
<dd>
<p>Do everything except actually send the updates.</p>
</dd>
<dt class="hdlist1">--force</dt>
<dd>
<p>Usually, the command refuses to update a remote ref that
is not an ancestor of the local ref used to overwrite it.
This flag disables the check.  This means that
the remote repository can lose commits; use it with
care.</p>
</dd>
<dt class="hdlist1">--verbose</dt>
<dd>
<p>Run verbosely.</p>
</dd>
<dt class="hdlist1">--thin</dt>
<dd>
<p>Send a "thin" pack, which records objects in deltified form based
on objects not included in the pack to reduce network traffic.</p>
</dd>
<dt class="hdlist1">--atomic</dt>
<dd>
<p>Use an atomic transaction for updating the refs. If any of the refs
fails to update then the entire push will fail without changing any
refs.</p>
</dd>
<dt class="hdlist1">--[no-]signed</dt>
<dt class="hdlist1">--signed=(true|false|if-asked)</dt>
<dd>
<p>GPG-sign the push request to update refs on the receiving
side, to allow it to be checked by the hooks and/or be
logged.  If <code>false</code> or <code>--no-signed</code>, no signing will be
attempted.  If <code>true</code> or <code>--signed</code>, the push will fail if the
server does not support signed pushes.  If set to <code>if-asked</code>,
sign if and only if the server supports signed pushes.  The push
will also fail if the actual call to <code>gpg</code> <code>--sign</code> fails.  See
<a href="git-receive-pack.html">git-receive-pack(1)</a> for the details on the receiving end.</p>
</dd>
<dt class="hdlist1">--push-option=&lt;string&gt;</dt>
<dd>
<p>Pass the specified string as a push option for consumption by
hooks on the server side.  If the server doesn&#8217;t support push
options, error out.  See <a href="git-push.html">git-push(1)</a> and
<a href="githooks.html">githooks(5)</a> for details.</p>
</dd>
<dt class="hdlist1">&lt;host&gt;</dt>
<dd>
<p>A remote host to house the repository.  When this
part is specified, <em>git-receive-pack</em> is invoked via
ssh.</p>
</dd>
<dt class="hdlist1">&lt;directory&gt;</dt>
<dd>
<p>The repository to update.</p>
</dd>
<dt class="hdlist1">&lt;ref&gt;&#8230;&#8203;</dt>

<p>The remote refs to update.</p>

<div class="sect1">
<h2 id="_specifying_the_refs">SPECIFYING THE REFS</h2>
<div class="sectionbody">
<div class="paragraph">
<p>There are three ways to specify which refs to update on the
remote end.</p>
</div>
<div class="paragraph">
<p>With the <code>--all</code> flag, all refs that exist locally are transferred to
the remote side.  You cannot specify any <em>&lt;ref&gt;</em> if you use
this flag.</p>
</div>
<div class="paragraph">
<p>Without <code>--all</code> and without any <em>&lt;ref&gt;</em>, the heads that exist
both on the local side and on the remote side are updated.</p>
</div>
<div class="paragraph">
<p>When one or more <em>&lt;ref&gt;</em> are specified explicitly (whether on the
command line or via <code>--stdin</code>), it can be either a
single pattern, or a pair of such patterns separated by a colon
":" (this means that a ref name cannot have a colon in it).  A
single pattern <em>&lt;name&gt;</em> is just shorthand for <em>&lt;name&gt;:&lt;name&gt;</em>.</p>
</div>
<div class="paragraph">
<p>Each pattern pair consists of the source side (before the colon)
and the destination side (after the colon).  The ref to be
pushed is determined by finding a match that matches the source
side, and where it is pushed is determined by using the
destination side. The rules used to match a ref are the same
rules used by <em>git rev-parse</em> to resolve a symbolic ref
name. See <a href="git-rev-parse.html">git-rev-parse(1)</a>.</p>
</div>
<div class="ulist">
<ul>
<li>
<p>It is an error if &lt;src&gt; does not match exactly one of the
local refs.</p>
</li>
<li>
<p>It is an error if &lt;dst&gt; matches more than one remote ref.</p>
</li>
<li>
<p>If &lt;dst&gt; does not match any remote ref, either</p>
<div class="ulist">
<ul>
<li>
<p>it has to start with "refs/"; &lt;dst&gt; is used as the
destination literally in this case.</p>
</li>
<li>
<p>&lt;src&gt; == &lt;dst&gt; and the ref that matched the &lt;src&gt; must not
exist in the set of remote refs; the ref matched &lt;src&gt;
locally is used as the name of the destination.</p>
</li>
</ul>
</div>
</li>
</ul>
</div>
<div class="paragraph">
<p>Without <code>--force</code>, the &lt;src&gt; ref is stored at the remote only if
&lt;dst&gt; does not exist, or &lt;dst&gt; is a proper subset (i.e. an
ancestor) of &lt;src&gt;.  This check, known as the "fast-forward check",
is performed to avoid accidentally overwriting the
remote ref and losing other people&#8217;s commits from there.</p>
</div>
<div class="paragraph">
<p>With <code>--force</code>, the fast-forward check is disabled for all refs.</p>
</div>
<div class="paragraph">
<p>Optionally, a &lt;ref&gt; parameter can be prefixed with a plus <em>+</em> sign
to disable the fast-forward check only on that ref.</p>
