<h2>NAME</h2>
<div class="sectionbody">
<p>git-pull -
Fetch from and integrate with another repository or a local branch
</p>
</div>
</div>
<div id="content">
<div class="sect1">
<h2 id="_synopsis">SYNOPSIS</h2>
<div class="sectionbody">
<div class="verseblock">
<pre class="content"><em>git pull</em> [options] [<repository> [<refspec>…]]</pre>
<div class="attribution">
</div></div>
</div>
</div>
<div class="sect1">
<h2 id="_description">DESCRIPTION</h2>
<div class="sectionbody">
<div class="paragraph"><p>Incorporates changes from a remote repository into the current
branch. In its default mode, <code>git pull</code> is shorthand for
<code>git fetch</code> followed by <code>git merge FETCH_HEAD</code>.</p></div>
<div class="paragraph"><p>More precisely, <em>git pull</em> runs <em>git fetch</em> with the given
parameters and calls <em>git merge</em> to merge the retrieved branch
heads into the current branch.
With <code>--rebase</code>, it runs <em>git rebase</em> instead of <em>git merge</em>.</p></div>
<div class="paragraph"><p><repository> should be the name of a remote repository as
passed to <a href="git-fetch.html">git-fetch(1)</a>. <refspec> can name an
arbitrary remote ref (for example, the name of a tag) or even
a collection of refs with corresponding remote-tracking branches
(e.g., refs/heads/*:refs/remotes/origin/*),
but usually it is the name of a branch in the remote repository.</p></div>
<div class="paragraph"><p>Default values for <repository> and <branch> are read from the
"remote" and "merge" configuration for the current branch
as set by <a href="git-branch.html">git-branch(1)</a> <code>--track</code>.</p></div>
<div class="paragraph"><p>Assume the following history exists and the current branch is
"<code>master</code>":</p></div>
<div class="listingblock">
<div class="content">
<pre><code> A---B---C master on origin
/
D---E---F---G master
^
origin/master in your repository</code></pre>
</div></div>
<div class="paragraph"><p>Then "<code>git pull</code>" will fetch and replay the changes from the remote
<code>master</code> branch since it diverged from the local <code>master</code> (i.e., <code>E</code>)
until its current commit (<code>C</code>) on top of <code>master</code> and record the
result in a new commit along with the names of the two parent commits
and a log message from the user describing the changes.</p></div>
<div class="listingblock">
<div class="content">
<pre><code> A---B---C origin/master
/ \
D---E---F---G---H master</code></pre>
</div></div>
<div class="paragraph"><p>See <a href="git-merge.html">git-merge(1)</a> for details, including how conflicts
are presented and handled.</p></div>
<div class="paragraph"><p>In Git 1.7.0 or later, to cancel a conflicting merge, use
<code>git reset --merge</code>. <strong>Warning</strong>: In older versions of Git, running <em>git pull</em>
with uncommitted changes is discouraged: while possible, it leaves you
in a state that may be hard to back out of in the case of a conflict.</p></div>
<div class="paragraph"><p>If any of the remote changes overlap with local uncommitted changes,
the merge will be automatically cancelled and the work tree untouched.
It is generally best to get any local changes in working order before
pulling or stash them away with <a href="git-stash.html">git-stash(1)</a>.</p></div>

<div class="dlist"><dl>

-q

<dt class="hdlist1">
--quiet
</dt>
<dd>
<p>
This is passed to both underlying git-fetch to squelch reporting of
during transfer, and underlying git-merge to squelch output during
merging.
</p>
</dd>
<dt class="hdlist1">
-v
</dt>
<dt class="hdlist1">
--verbose

Pass --verbose to git-fetch and git-merge.
</p>

<dt class="hdlist1">
--[no-]recurse-submodules[=yes|on-demand|no]
</dt>
<dd>
<p>
This option controls if new commits of all populated submodules should
be fetched too (see <a href="git-config.html">git-config(1)</a> and <a href="gitmodules.html">gitmodules(5)</a>).
That might be necessary to get the data needed for merging submodule
commits, a feature Git learned in 1.7.3. Notice that the result of a
merge will not be checked out in the submodule, "git submodule update"
has to be called afterwards to bring the work tree up to date with the
merge result.

<div class="dlist"><dl>
<dt class="hdlist1">
--commit
</dt>
<dt class="hdlist1">
--no-commit
</dt>
<dd>
<p>
Perform the merge and commit the result. This option can
be used to override --no-commit.
</p>
<div class="paragraph"><p>With --no-commit perform the merge but pretend the merge
failed and do not autocommit, to give the user a chance to
inspect and further tweak the merge result before committing.</p></div>

<dt class="hdlist1">
--edit
</dt>
<dt class="hdlist1">
-e
</dt>
<dt class="hdlist1">
--no-edit
</dt>
<dd>
<p>
Invoke an editor before committing successful mechanical merge to
further edit the auto-generated merge message, so that the user
can explain and justify the merge. The <code>--no-edit</code> option can be
used to accept the auto-generated message (this is generally
discouraged).
</p>
<div class="paragraph"><p>Older scripts may depend on the historical behaviour of not allowing the
user to edit the merge log message. They will see an editor opened when
they run <code>git merge</code>. To make it easier to adjust such scripts to the
updated behaviour, the environment variable <code>GIT_MERGE_AUTOEDIT</code> can be
set to <code>no</code> at the beginning of them.</p></div>
</dd>
<dt class="hdlist1">
--ff
</dt>
<dd>
<p>
When the merge resolves as a fast-forward, only update the branch
pointer, without creating a merge commit. This is the default
behavior.
</p>
</dd>
<dt class="hdlist1">
--no-ff
</dt>
<dd>
<p>
Create a merge commit even when the merge resolves as a
fast-forward. This is the default behaviour when merging an
annotated (and possibly signed) tag.
</p>
</dd>
<dt class="hdlist1">
--ff-only
</dt>
<dd>
<p>
Refuse to merge and exit with a non-zero status unless the
current <code>HEAD</code> is already up-to-date or the merge can be
resolved as a fast-forward.
</p>
</dd>
<dt class="hdlist1">
--log[=<n>]
</dt>
<dt class="hdlist1">
--no-log
</dt>
<dd>
<p>
In addition to branch names, populate the log message with
one-line descriptions from at most <n> actual commits that are being
merged. See also <a href="git-fmt-merge-msg.html">git-fmt-merge-msg(1)</a>.
</p>
<div class="paragraph"><p>With --no-log do not list one-line descriptions from the

--stat
</dt>
<dt class="hdlist1">
-n
</dt>
<dt class="hdlist1">
--no-stat

<p>
Show a diffstat at the end of the merge. The diffstat is also
controlled by the configuration option merge.stat.
</p>
<div class="paragraph"><p>With -n or --no-stat do not show a diffstat at the end of the
merge.</p></div>
</dd>
<dt class="hdlist1">
--squash
</dt>
<dt class="hdlist1">
--no-squash

<p>
Produce the working tree and index state as if a real merge
happened (except for the merge information), but do not actually
make a commit, move the <code>HEAD</code>, or record <code>$GIT_DIR/MERGE_HEAD</code>
(to cause the next <code>git commit</code> command to create a merge
commit). This allows you to create a single commit on top of
the current branch whose effect is the same as merging another
branch (or more in case of an octopus).
</p>
<div class="paragraph"><p>With --no-squash perform the merge and commit the result. This

<dd>
<p>
Use the given merge strategy; can be supplied more than
once to specify them in the order they should be tried.
If there is no <code>-s</code> option, a built-in list of strategies
is used instead (<em>git merge-recursive</em> when merging a single
head, <em>git merge-octopus</em> otherwise).
