<div class="paragraph"><p>Fetch branches and/or tags (collectively, "refs") from one or more | |
other repositories, along with the objects necessary to complete their | |
histories. Remote-tracking branches are updated (see the description | |
of <refspec> below for ways to control this behavior).</p></div> | |
<div class="paragraph"><p>By default, any tag that points into the histories being fetched is | |
also fetched; the effect is to fetch tags that | |
point at branches that you are interested in. This default behavior | |
can be changed by using the --tags or --no-tags options or by | |
configuring remote.<name>.tagOpt. By using a refspec that fetches tags | |
explicitly, you can fetch tags that do not point into branches you | |
are interested in as well.</p></div> | |
<div class="paragraph"><p><em>git fetch</em> can fetch from either a single named repository or URL, | |
or from several repositories at once if <group> is given and | |
there is a remotes.<group> entry in the configuration file. | |
(See <a href="git-config.html">git-config(1)</a>).</p></div> | |
<div class="paragraph"><p>When no remote is specified, by default the <code>origin</code> remote will be used, | |
unless there’s an upstream branch configured for the current branch.</p></div> | |
<div class="paragraph"><p>The names of refs that are fetched, together with the object names | |
they point at, are written to <code>.git/FETCH_HEAD</code>. This information | |
may be used by scripts or other git commands, such as <a href="git-pull.html">git-pull(1)</a>.</p></div> | |

<div class="ulist"><ul> | |
<li> | |

<div class="sectionbody"> | |
<div class="paragraph"><p>You often interact with the same remote repository by | |
regularly and repeatedly fetching from it. In order to keep track | |
of the progress of such a remote repository, <code>git fetch</code> allows you | |
to configure <code>remote.<repository>.fetch</code> configuration variables.</p></div> | |
<div class="paragraph"><p>Typically such a variable may look like this:</p></div> | |
<div class="listingblock"> | |
<div class="content"> | |
<pre><code>[remote "origin"] | |
fetch = +refs/heads/*:refs/remotes/origin/*</code></pre> | |
</div></div> | |
<div class="paragraph"><p>This configuration is used in two ways:</p></div> | |
<div class="ulist"><ul> | |
<li> | |
<p> | |
When <code>git fetch</code> is run without specifying what branches | |
and/or tags to fetch on the command line, e.g. <code>git fetch origin</code> | |
or <code>git fetch</code>, <code>remote.<repository>.fetch</code> values are used as | |
the refspecs—they specify which refs to fetch and which local refs | |
to update. The example above will fetch | |
all branches that exist in the <code>origin</code> (i.e. any ref that matches | |
the left-hand side of the value, <code>refs/heads/*</code>) and update the | |
corresponding remote-tracking branches in the <code>refs/remotes/origin/*</code> | |
hierarchy. | |
</p> | |
</li> | |
<li> | |
<p> | |
When <code>git fetch</code> is run with explicit branches and/or tags | |
to fetch on the command line, e.g. <code>git fetch origin master</code>, the | |
<refspec>s given on the command line determine what are to be | |
fetched (e.g. <code>master</code> in the example, | |
which is a short-hand for <code>master:</code>, which in turn means | |
"fetch the <em>master</em> branch but I do not explicitly say what | |
remote-tracking branch to update with it from the command line"), | |
and the example command will | |
fetch <em>only</em> the <em>master</em> branch. The <code>remote.<repository>.fetch</code> | |
values determine which | |
remote-tracking branch, if any, is updated. When used in this | |
way, the <code>remote.<repository>.fetch</code> values do not have any | |
effect in deciding <em>what</em> gets fetched (i.e. the values are not | |
used as refspecs when the command-line lists refspecs); they are | |

<div class="sectionbody"> | |
<div class="paragraph"><p>The output of "git fetch" depends on the transport method used; this | |
section describes the output when fetching over the Git protocol | |
(either locally or via ssh) and Smart HTTP protocol.</p></div> | |
<div class="paragraph"><p>The status of the fetch is output in tabular form, with each line | |
representing the status of a single ref. Each line is of the form:</p></div> | |
<div class="listingblock"> | |
<div class="content"> | |
<pre><code> <flag> <summary> <from> -> <to> [<reason>]</code></pre> | |
</div></div> | |
<div class="paragraph"><p>The status of up-to-date refs is shown only if the --verbose option is | |
used.</p></div> | |
<div class="paragraph"><p>In compact output mode, specified with configuration variable | |
fetch.output, if either entire <code><from></code> or <code><to></code> is found in the | |
other string, it will be substituted with <code>*</code> in the other string. For | |
example, <code>master -> origin/master</code> becomes <code>master -> origin/*</code>.</p></div> | |

For a successfully fetched ref, the summary shows the old and new | |
values of the ref in a form suitable for using as an argument to | |

the remote ref is "(none)". | |

Update the remote-tracking branches: | |
</p> | |
<div class="listingblock"> | |
<div class="content"> | |
<pre><code>$ git fetch origin</code></pre> | |
</div></div> | |
<div class="paragraph"><p>The above command copies all branches from the remote refs/heads/ | |
namespace and stores them to the local refs/remotes/origin/ namespace, | |
unless the branch.<name>.fetch option is used to specify a non-default | |
refspec.</p></div> | |
</li> | |
<li> | |
<p> | |
Using refspecs explicitly: | |
</p> | |
<div class="listingblock"> | |
<div class="content"> | |
<pre><code>$ git fetch origin +pu:pu maint:tmp</code></pre> | |
</div></div> | |
<div class="paragraph"><p>This updates (or creates, as necessary) branches <code>pu</code> and <code>tmp</code> in | |
the local repository by fetching from the branches (respectively) | |
<code>pu</code> and <code>maint</code> from the remote repository.</p></div> | |
<div class="paragraph"><p>The <code>pu</code> branch will be updated even if it is does not fast-forward, | |
because it is prefixed with a plus sign; <code>tmp</code> will not be.</p></div> | |
</li> | |
<li> | |
<p> | |
Peek at a remote’s branch, without configuring the remote in your local | |
repository: | |
</p> | |
<div class="listingblock"> | |
<div class="content"> | |
<pre><code>$ git fetch git://git.kernel.org/pub/scm/git/git.git maint | |
$ git log FETCH_HEAD</code></pre> | |
</div></div> | |
<div class="paragraph"><p>The first command fetches the <code>maint</code> branch from the repository at | |
<code>git://git.kernel.org/pub/scm/git/git.git</code> and the second command uses | |
<code>FETCH_HEAD</code> to examine the branch with <a href="git-log.html">git-log(1)</a>. The fetched | |
objects will eventually be removed by git’s built-in housekeeping (see | |
<a href="git-gc.html">git-gc(1)</a>).</p></div> | |

<div class="sect1"> | |
<h2 id="_bugs">BUGS</h2> | |
<div class="sectionbody"> | |
<div class="paragraph"><p>Using --recurse-submodules can only fetch new commits in already checked | |
out submodules right now. When e.g. upstream added a new submodule in the | |
just fetched commits of the superproject the submodule itself can not be | |
fetched, making it impossible to check out that submodule later without | |
having to do a fetch again. This is expected to be fixed in a future Git | |
version.</p></div> | |
