   1-a, \--append::
   2        Append ref names and object names of fetched refs to the
   3        existing contents of `.git/FETCH_HEAD`.  Without this
   4        option old data in `.git/FETCH_HEAD` will be overwritten.
   5
   6\--upload-pack <upload-pack>::
   7        When given, and the repository to fetch from is handled
   8        by 'git-fetch-pack', '--exec=<upload-pack>' is passed to
   9        the command to specify non-default path for the command
  10        run on the other end.
  11
  12-f, \--force::
  13        When `git-fetch` is used with `<rbranch>:<lbranch>`
  14        refspec, it refuses to update the local branch
  15        `<lbranch>` unless the remote branch `<rbranch>` it
  16        fetches is a descendant of `<lbranch>`.  This option
  17        overrides that check.
  18
  19\--no-tags::
  20        By default, `git-fetch` fetches tags that point at
  21        objects that are downloaded from the remote repository
  22        and stores them locally.  This option disables this
  23        automatic tag following.
  24
  25-t, \--tags::
  26        Most of the tags are fetched automatically as branch
  27        heads are downloaded, but tags that do not point at
  28        objects reachable from the branch heads that are being
  29        tracked will not be fetched by this mechanism.  This
  30        flag lets all tags and their associated objects be
  31        downloaded.
  32
  33-k, \--keep::
  34        Keep downloaded pack.
  35
  36-u, \--update-head-ok::
  37        By default `git-fetch` refuses to update the head which
  38        corresponds to the current branch.  This flag disables the
  39        check.  This is purely for the internal use for `git-pull`
  40        to communicate with `git-fetch`, and unless you are
  41        implementing your own Porcelain you are not supposed to
  42        use it.
  43
  44\--depth=<depth>::
  45        Deepen the history of a 'shallow' repository created by
  46        `git clone` with `--depth=<depth>` option (see gitlink:git-clone[1])
  47        by the specified number of commits.
