-a, \--append:: Append ref names and object names of fetched refs to the existing contents of `.git/FETCH_HEAD`. Without this option old data in `.git/FETCH_HEAD` will be overwritten. \--upload-pack :: When given, and the repository to fetch from is handled by 'git-fetch-pack', '--exec=' is passed to the command to specify non-default path for the command run on the other end. -f, \--force:: When `git-fetch` is used with `:` refspec, it refuses to update the local branch `` unless the remote branch `` it fetches is a descendant of ``. This option overrides that check. \--no-tags:: By default, `git-fetch` fetches tags that point at objects that are downloaded from the remote repository and stores them locally. This option disables this automatic tag following. -t, \--tags:: Most of the tags are fetched automatically as branch heads are downloaded, but tags that do not point at objects reachable from the branch heads that are being tracked will not be fetched by this mechanism. This flag lets all tags and their associated objects be downloaded. -k, \--keep:: Keep downloaded pack. -u, \--update-head-ok:: By default `git-fetch` refuses to update the head which corresponds to the current branch. This flag disables the check. Note that fetching into the current branch will not update the index and working directory, so use it with care.
