git-fetch(1)
============

NAME
----
git-fetch - Download objects and refs from another repository


SYNOPSIS
--------
[verse]
'git fetch' [<options>] [<repository> [<refspec>...]]
'git fetch' [<options>] <group>
'git fetch' --multiple [<options>] [(<repository> | <group>)...]
'git fetch' --all [<options>]


DESCRIPTION
-----------
Fetches named heads or tags from one or more other repositories,
along with the objects necessary to complete them.

The ref names and their object names of fetched refs are stored
in `.git/FETCH_HEAD`.  This information is left for a later merge
operation done by 'git merge'.

By default, tags are auto-followed.  This means that when fetching
from a remote, any tags on the remote that point to objects that exist
in the local repository are 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, by
configuring remote.<name>.tagopt, or by using a refspec that fetches
tags explicitly.

'git fetch' can fetch from either a single named repository,
or from several repositories at once if <group> is given and
there is a remotes.<group> entry in the configuration file.
(See linkgit:git-config[1]).

When no remote is specified, by default the `origin` remote will be used,
unless there's an upstream branch configured for the current branch.

EXAMPLES
--------

* Update the remote-tracking branches:
+
------------------------------------------------
$ git fetch origin
------------------------------------------------
+
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.

* Using refspecs explicitly:
+
------------------------------------------------
$ git fetch origin +pu:pu maint:tmp
------------------------------------------------
+
This updates (or creates, as necessary) branches `pu` and `tmp` in
the local repository by fetching from the branches (respectively)
`pu` and `maint` from the remote repository.
+
The `pu` branch will be updated even if it is does not fast-forward,
because it is prefixed with a plus sign; `tmp` will not be.


BUGS
----
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.
