  18DESCRIPTION
  19-----------
  20Fetches named heads or tags from one or more other repositories,
  21along with the objects necessary to complete them.
  22
  23The ref names and their object names of fetched refs are stored
  24in `.git/FETCH_HEAD`.  This information is left for a later merge
  25operation done by 'git merge'.
  26
  27When <refspec> stores the fetched result in remote-tracking branches,
  28the tags that point at these branches are automatically
  29followed.  This is done by first fetching from the remote using
  30the given <refspec>s, and if the repository has objects that are
  31pointed by remote tags that it does not yet have, then fetch
  32those missing tags.  If the other end has tags that point at
  33branches you are not interested in, you will not get them.
  34
  35'git fetch' can fetch from either a single named repository,
  36or from several repositories at once if <group> is given and
  37there is a remotes.<group> entry in the configuration file.
  38(See linkgit:git-config[1]).

  49EXAMPLES
  50--------
  51
  52* Update the remote-tracking branches:
  53+
  54------------------------------------------------
  55$ git fetch origin
  56------------------------------------------------
  57+
  58The above command copies all branches from the remote refs/heads/
  59namespace and stores them to the local refs/remotes/origin/ namespace,
  60unless the branch.<name>.fetch option is used to specify a non-default
  61refspec.
  62
  63* Using refspecs explicitly:
  64+
  65------------------------------------------------
  66$ git fetch origin +pu:pu maint:tmp
  67------------------------------------------------
  68+
  69This updates (or creates, as necessary) branches `pu` and `tmp` in
  70the local repository by fetching from the branches (respectively)
  71`pu` and `maint` from the remote repository.
  72+
  73The `pu` branch will be updated even if it is does not fast-forward,
  74because it is prefixed with a plus sign; `tmp` will not be.

  77BUGS
  78----
  79Using --recurse-submodules can only fetch new commits in already checked
  80out submodules right now. When e.g. upstream added a new submodule in the
  81just fetched commits of the superproject the submodule itself can not be
  82fetched, making it impossible to check out that submodule later without
  83having to do a fetch again. This is expected to be fixed in a future Git
  84version.
