<div class="dlist"><dl>
<dt class="hdlist1">
&lt;repository&gt;
</dt>
<dd>
<p>
The "remote" repository that is destination of a push
operation. This parameter can be either a URL
(see the section <a href="#URLS">GIT URLS</a> below) or the name
of a remote (see the section <a href="#REMOTES">REMOTES</a> below).
</p>
</dd>
<dt class="hdlist1">
&lt;refspec&gt;&#8230;
</dt>
<dd>
<p>
The format of a &lt;refspec&gt; parameter is an optional plus
<tt>&#43;</tt>, followed by the source ref &lt;src&gt;, followed
by a colon <tt>:</tt>, followed by the destination ref &lt;dst&gt;.
It is used to specify with what &lt;src&gt; object the &lt;dst&gt; ref
in the remote repository is to be updated.
</p>
<div class="paragraph"><p>The &lt;src&gt; is often the name of the branch you would want to push, but
it can be any arbitrary "SHA-1 expression", such as <tt>master~4</tt> or
<tt>HEAD</tt> (see <a href="gitrevisions.html">gitrevisions(7)</a>).</p></div>
<div class="paragraph"><p>The &lt;dst&gt; tells which ref on the remote side is updated with this
push. Arbitrary expressions cannot be used here, an actual ref must
be named. If <tt>:</tt>&lt;dst&gt; is omitted, the same ref as &lt;src&gt; will be
updated.</p></div>
<div class="paragraph"><p>The object referenced by &lt;src&gt; is used to update the &lt;dst&gt; reference
on the remote side, but by default this is only allowed if the
update can fast-forward &lt;dst&gt;. By having the optional leading <tt>&#43;</tt>,
you can tell git to update the &lt;dst&gt; ref even when the update is not a
fast-forward. This does <strong>not</strong> attempt to merge &lt;src&gt; into &lt;dst&gt;. See
EXAMPLES below for details.</p></div>
<div class="paragraph"><p><tt>tag &lt;tag&gt;</tt> means the same as <tt>refs/tags/&lt;tag&gt;:refs/tags/&lt;tag&gt;</tt>.</p></div>
<div class="paragraph"><p>Pushing an empty &lt;src&gt; allows you to delete the &lt;dst&gt; ref from
the remote repository.</p></div>
<div class="paragraph"><p>The special refspec <tt>:</tt> (or <tt>&#43;:</tt> to allow non-fast-forward updates)
directs git to push "matching" branches: for every branch that exists on
the local side, the remote side is updated if a branch of the same name
already exists on the remote side. This is the default operation mode
if no explicit refspec is found (that is neither on the command line
nor in any Push line of the corresponding remotes file---see below).</p></div>
</dd>
<dt class="hdlist1">
--all
</dt>
<dd>
<p>
Instead of naming each ref to push, specifies that all
refs under <tt>refs/heads/</tt> be pushed.
</p>
</dd>
<dt class="hdlist1">
--mirror
</dt>
<dd>
<p>
Instead of naming each ref to push, specifies that all
refs under <tt>refs/</tt> (which includes but is not
limited to <tt>refs/heads/</tt>, <tt>refs/remotes/</tt>, and <tt>refs/tags/</tt>)
be mirrored to the remote repository. Newly created local
refs will be pushed to the remote end, locally updated refs
will be force updated on the remote end, and deleted refs
will be removed from the remote end. This is the default
if the configuration option <tt>remote.&lt;remote&gt;.mirror</tt> is
set.
</p>
</dd>
<dt class="hdlist1">
-n
</dt>
<dt class="hdlist1">
--dry-run
</dt>
<dd>
<p>
Do everything except actually send the updates.
</p>
</dd>
<dt class="hdlist1">
--porcelain
</dt>
<dd>
<p>
Produce machine-readable output. The output status line for each ref
will be tab-separated and sent to stdout instead of stderr. The full
symbolic names of the refs will be given.
</p>
</dd>
<dt class="hdlist1">
--delete
</dt>
<dd>
<p>
All listed refs are deleted from the remote repository. This is
the same as prefixing all refs with a colon.
</p>
</dd>
<dt class="hdlist1">
--tags
</dt>
<dd>
<p>
All refs under <tt>refs/tags</tt> are pushed, in
addition to refspecs explicitly listed on the command
line.
</p>
</dd>
<dt class="hdlist1">
--receive-pack=&lt;git-receive-pack&gt;
</dt>
<dt class="hdlist1">
--exec=&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">
-f
</dt>
<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 can cause the
remote repository to lose commits; use it with care.
</p>
</dd>
<dt class="hdlist1">
--repo=&lt;repository&gt;
</dt>
<dd>
<p>
This option is only relevant if no &lt;repository&gt; argument is
passed in the invocation. In this case, <em>git push</em> derives the
remote name from the current branch: If it tracks a remote
branch, then that remote repository is pushed to. Otherwise,
the name "origin" is used. For this latter case, this option
can be used to override the name "origin". In other words,
the difference between these two commands
</p>
<div class="listingblock">
<div class="content">
<pre><tt>git push public #1
git push --repo=public #2</tt></pre>
</div></div>
<div class="paragraph"><p>is that #1 always pushes to "public" whereas #2 pushes to "public"
only if the current branch does not track a remote branch. This is
useful if you write an alias or script around <em>git push</em>.</p></div>
</dd>
<dt class="hdlist1">
-u
</dt>
<dt class="hdlist1">
--set-upstream
</dt>
<dd>
<p>
For every branch that is up to date or successfully pushed, add
upstream (tracking) reference, used by argument-less
<a href="git-pull.html">git-pull(1)</a> and other commands. For more information,
see <em>branch.&lt;name&gt;.merge</em> in <a href="git-config.html">git-config(1)</a>.
</p>
</dd>
<dt class="hdlist1">
--thin
</dt>
<dt class="hdlist1">
--no-thin
</dt>
<dd>
<p>
These options are passed to <a href="git-send-pack.html">git-send-pack(1)</a>. A thin transfer
significantly reduces the amount of sent data when the sender and
receiver share many of the same objects in common. The default is
--thin.
</p>
</dd>
<dt class="hdlist1">
-q
</dt>
<dt class="hdlist1">
--quiet
</dt>
<dd>
<p>
Suppress all output, including the listing of updated refs,
unless an error occurs. Progress is not reported to the standard
error stream.
</p>
</dd>
<dt class="hdlist1">
-v
</dt>
<dt class="hdlist1">
--verbose
</dt>
<dd>
<p>
Run verbosely.
</p>
</dd>
<dt class="hdlist1">
--progress
</dt>
<dd>
<p>
Progress status is reported on the standard error stream
by default when it is attached to a terminal, unless -q
is specified. This flag forces progress status even if the
standard error stream is not directed to a terminal.

<div class="sectionbody">
<div class="paragraph"><p>In general, URLs contain information about the transport protocol, the
address of the remote server, and the path to the repository.
Depending on the transport protocol, some of this information may be
absent.</p></div>
<div class="paragraph"><p>Git natively supports ssh, git, http, https, ftp, ftps, and rsync
protocols. The following syntaxes may be used with them:</p></div>
<div class="ulist"><ul>
<li>
<p>
ssh://&#91;user@&#93;host.xz&#91;:port&#93;/path/to/repo.git/
</p>

</p>
</li>
<li>
<p>
rsync://host.xz/path/to/repo.git/
</p>
</li>
</ul></div>
<div class="paragraph"><p>An alternative scp-like syntax may also be used with the ssh protocol:</p></div>
<div class="ulist"><ul>
<li>
<p>
&#91;user@&#93;host.xz:path/to/repo.git/
</p>
</li>
</ul></div>
<div class="paragraph"><p>The ssh and git protocols additionally support ~username expansion:</p></div>
<div class="ulist"><ul>
<li>
<p>
ssh://&#91;user@&#93;host.xz&#91;:port&#93;/~&#91;user&#93;/path/to/repo.git/

</li>
<li>
<p>
git://host.xz&#91;:port&#93;/~&#91;user&#93;/path/to/repo.git/

<li>
<p>
&#91;user@&#93;host.xz:/~&#91;user&#93;/path/to/repo.git/
</p>
</li>
</ul></div>
<div class="paragraph"><p>For local repositories, also supported by git natively, the following
syntaxes may be used:</p></div>
<div class="ulist"><ul>
<li>
<p>
/path/to/repo.git/
</p>
</li>
<li>
<p>
<a href="file:///path/to/repo.git/">file:///path/to/repo.git/</a>
</p>
</li>
</ul></div>
<div class="paragraph"><p>These two syntaxes are mostly equivalent, except when cloning, when
the former implies --local option. See <a href="git-clone.html">git-clone(1)</a> for
details.</p></div>
<div class="paragraph"><p>When git doesn&#8217;t know how to handle a certain transport protocol, it
attempts to use the <em>remote-&lt;transport&gt;</em> remote helper, if one
exists. To explicitly request a remote helper, the following syntax
may be used:</p></div>
<div class="ulist"><ul>
<li>
<p>
&lt;transport&gt;::&lt;address&gt;
</p>
</li>
</ul></div>
<div class="paragraph"><p>where &lt;address&gt; may be a path, a server and path, or an arbitrary
URL-like string recognized by the specific remote helper being
invoked. See <a href="git-remote-helpers.html">git-remote-helpers(1)</a> for details.</p></div>
<div class="paragraph"><p>If there are a large number of similarly-named remote repositories and
you want to use a different format for them (such that the URLs you
use will be rewritten into URLs that work), you can create a
configuration section of the form:</p></div>
<div class="listingblock">
<div class="content">
<pre><tt> [url "&lt;actual url base&gt;"]
insteadOf = &lt;other url base&gt;</tt></pre>
</div></div>
<div class="paragraph"><p>For example, with this:</p></div>
<div class="listingblock">
<div class="content">
<pre><tt> [url "git://git.host.xz/"]
insteadOf = host.xz:/path/to/
insteadOf = work:</tt></pre>
</div></div>
<div class="paragraph"><p>a URL like "work:repo.git" or like "host.xz:/path/to/repo.git" will be
rewritten in any context that takes a URL to be "git://git.host.xz/repo.git".</p></div>
<div class="paragraph"><p>If you want to rewrite URLs for push only, you can create a
configuration section of the form:</p></div>
<div class="listingblock">
<div class="content">
<pre><tt> [url "&lt;actual url base&gt;"]
pushInsteadOf = &lt;other url base&gt;</tt></pre>
</div></div>
<div class="paragraph"><p>For example, with this:</p></div>
<div class="listingblock">
<div class="content">
<pre><tt> [url "ssh://example.org/"]
pushInsteadOf = git://example.org/</tt></pre>
</div></div>
<div class="paragraph"><p>a URL like "git://example.org/path/to/repo.git" will be rewritten to
"ssh://example.org/path/to/repo.git" for pushes, but pulls will still
use the original URL.</p></div>

<h2 id="_note_about_fast_forwards">Note about fast-forwards</h2>
<div class="sectionbody">
<div class="paragraph"><p>When an update changes a branch (or more in general, a ref) that used to
point at commit A to point at another commit B, it is called a
fast-forward update if and only if B is a descendant of A.</p></div>
<div class="paragraph"><p>In a fast-forward update from A to B, the set of commits that the original
commit A built on top of is a subset of the commits the new commit B
builds on top of. Hence, it does not lose any history.</p></div>
<div class="paragraph"><p>In contrast, a non-fast-forward update will lose history. For example,
suppose you and somebody else started at the same commit X, and you built
a history leading to commit B while the other person built a history
leading to commit A. The history looks like this:</p></div>
<div class="listingblock">
<div class="content">
<pre><tt> B
/
---X---A</tt></pre>
</div></div>
<div class="paragraph"><p>Further suppose that the other person already pushed changes leading to A
back to the original repository you two obtained the original commit X.</p></div>
<div class="paragraph"><p>The push done by the other person updated the branch that used to point at
commit X to point at commit A. It is a fast-forward.</p></div>
<div class="paragraph"><p>But if you try to push, you will attempt to update the branch (that
now points at A) with commit B. This does <em>not</em> fast-forward. If you did
so, the changes introduced by commit A will be lost, because everybody
will now start building on top of B.</p></div>
<div class="paragraph"><p>The command by default does not allow an update that is not a fast-forward
to prevent such loss of history.</p></div>
<div class="paragraph"><p>If you do not want to lose your work (history from X to B) nor the work by
the other person (history from X to A), you would need to first fetch the
history from the repository, create a history that contains changes done
by both parties, and push the result back.</p></div>
<div class="paragraph"><p>You can perform "git pull", resolve potential conflicts, and "git push"
the result. A "git pull" will create a merge commit C between commits A
and B.</p></div>
<div class="listingblock">
<div class="content">
<pre><tt> B---C
/ /
---X---A</tt></pre>
</div></div>
<div class="paragraph"><p>Updating A with the resulting merge commit will fast-forward and your
push will be accepted.</p></div>
<div class="paragraph"><p>Alternatively, you can rebase your change between X and B on top of A,
with "git pull --rebase", and push the result back. The rebase will
create a new commit D that builds the change between X and B on top of
A.</p></div>
<div class="listingblock">
<div class="content">
<pre><tt> B D
/ /
---X---A</tt></pre>
</div></div>
<div class="paragraph"><p>Again, updating A with this commit will fast-forward and your push will be
accepted.</p></div>
<div class="paragraph"><p>There is another common situation where you may encounter non-fast-forward
rejection when you try to push, and it is possible even when you are
pushing into a repository nobody else pushes into. After you push commit
A yourself (in the first picture in this section), replace it with "git
commit --amend" to produce commit B, and you try to push it out, because
forgot that you have pushed A out already. In such a case, and only if
you are certain that nobody in the meantime fetched your earlier commit A
(and started building on top of it), you can run "git push --force" to
overwrite it. In other words, "git push --force" is a method reserved for
a case where you do mean to lose history.</p></div>

<h2 id="_examples">Examples</h2>
<div class="sectionbody">
<div class="dlist"><dl>
<dt class="hdlist1">
git push
</dt>
<dd>
<p>
Works like <tt>git push &lt;remote&gt;</tt>, where &lt;remote&gt; is the
current branch&#8217;s remote (or <tt>origin</tt>, if no remote is
configured for the current branch).
</p>
</dd>
<dt class="hdlist1">
git push origin
</dt>
<dd>
<p>
Without additional configuration, works like
<tt>git push origin :</tt>.
</p>
<div class="paragraph"><p>The default behavior of this command when no &lt;refspec&gt; is given can be
configured by setting the <tt>push</tt> option of the remote.</p></div>
<div class="paragraph"><p>For example, to default to pushing only the current branch to <tt>origin</tt>
use <tt>git config remote.origin.push HEAD</tt>. Any valid &lt;refspec&gt; (like
the ones in the examples below) can be configured as the default for
<tt>git push origin</tt>.</p></div>
<div class="dlist"><dl>
<dt class="hdlist1">
git push origin
</dt>
<dd>
<p>
Push "matching" branches to <tt>origin</tt>. See
&lt;refspec&gt; in the <a href="#OPTIONS">OPTIONS</a> section above for a
description of "matching" branches.
</p>
</dd>
</dl></div>
</dd>
<dt class="hdlist1">
git push origin master
</dt>
<dd>
<p>
Find a ref that matches <tt>master</tt> in the source repository
(most likely, it would find <tt>refs/heads/master</tt>), and update
the same ref (e.g. <tt>refs/heads/master</tt>) in <tt>origin</tt> repository
with it. If <tt>master</tt> did not exist remotely, it would be
created.
</p>
</dd>
<dt class="hdlist1">
git push origin HEAD
</dt>
<dd>
<p>
A handy way to push the current branch to the same name on the
remote.
</p>
</dd>
<dt class="hdlist1">
git push origin master:satellite/master dev:satellite/dev
</dt>
<dd>
<p>
Use the source ref that matches <tt>master</tt> (e.g. <tt>refs/heads/master</tt>)
to update the ref that matches <tt>satellite/master</tt> (most probably
<tt>refs/remotes/satellite/master</tt>) in the <tt>origin</tt> repository, then
do the same for <tt>dev</tt> and <tt>satellite/dev</tt>.
</p>
</dd>
<dt class="hdlist1">
git push origin HEAD:master
</dt>
<dd>
<p>
Push the current branch to the remote ref matching <tt>master</tt> in the
<tt>origin</tt> repository. This form is convenient to push the current
branch without thinking about its local name.
</p>
</dd>
<dt class="hdlist1">
git push origin master:refs/heads/experimental
</dt>
<dd>
<p>
Create the branch <tt>experimental</tt> in the <tt>origin</tt> repository
by copying the current <tt>master</tt> branch. This form is only
needed to create a new branch or tag in the remote repository when
the local name and the remote name are different; otherwise,
the ref name on its own will work.
</p>
</dd>
<dt class="hdlist1">
git push origin :experimental
</dt>
<dd>
<p>
Find a ref that matches <tt>experimental</tt> in the <tt>origin</tt> repository
(e.g. <tt>refs/heads/experimental</tt>), and delete it.
</p>
</dd>
<dt class="hdlist1">
git push origin &#43;dev:master
</dt>
<dd>
<p>
Update the origin repository&#8217;s master branch with the dev branch,
allowing non-fast-forward updates. <strong>This can leave unreferenced
commits dangling in the origin repository.</strong> Consider the
following situation, where a fast-forward is not possible:
</p>
<div class="listingblock">
<div class="content">
<pre><tt> o---o---o---A---B origin/master
\
X---Y---Z dev</tt></pre>
</div></div>
<div class="paragraph"><p>The above command would change the origin repository to</p></div>
<div class="listingblock">
<div class="content">
<pre><tt> A---B (unnamed branch)
/
o---o---o---X---Y---Z master</tt></pre>
</div></div>
<div class="paragraph"><p>Commits A and B would no longer belong to a branch with a symbolic name,
and so would be unreachable. As such, these commits would be removed by
a <tt>git gc</tt> command on the origin repository.</p></div>
