   1--commit::
   2--no-commit::
   3        Perform the merge and commit the result. This option can
   4        be used to override --no-commit.
   5+
   6With --no-commit perform the merge and stop just before creating
   7a merge commit, to give the user a chance to inspect and further
   8tweak the merge result before committing.
   9+
  10Note that fast-forward updates do not create a merge commit and
  11therefore there is no way to stop those merges with --no-commit.
  12Thus, if you want to ensure your branch is not changed or updated
  13by the merge command, use --no-ff with --no-commit.
  14
  15--edit::
  16-e::
  17--no-edit::
  18        Invoke an editor before committing successful mechanical merge to
  19        further edit the auto-generated merge message, so that the user
  20        can explain and justify the merge. The `--no-edit` option can be
  21        used to accept the auto-generated message (this is generally
  22        discouraged).
  23ifndef::git-pull[]
  24The `--edit` (or `-e`) option is still useful if you are
  25giving a draft message with the `-m` option from the command line
  26and want to edit it in the editor.
  27endif::git-pull[]
  28+
  29Older scripts may depend on the historical behaviour of not allowing the
  30user to edit the merge log message. They will see an editor opened when
  31they run `git merge`. To make it easier to adjust such scripts to the
  32updated behaviour, the environment variable `GIT_MERGE_AUTOEDIT` can be
  33set to `no` at the beginning of them.
  34
  35--ff::
  36        When the merge resolves as a fast-forward, only update the branch
  37        pointer, without creating a merge commit.  This is the default
  38        behavior.
  39
  40--no-ff::
  41        Create a merge commit even when the merge resolves as a
  42        fast-forward.  This is the default behaviour when merging an
  43        annotated (and possibly signed) tag that is not stored in
  44        its natural place in 'refs/tags/' hierarchy.
  45
  46--ff-only::
  47        Refuse to merge and exit with a non-zero status unless the
  48        current `HEAD` is already up to date or the merge can be
  49        resolved as a fast-forward.
  50
  51-S[<keyid>]::
  52--gpg-sign[=<keyid>]::
  53        GPG-sign the resulting merge commit. The `keyid` argument is
  54        optional and defaults to the committer identity; if specified,
  55        it must be stuck to the option without a space.
  56
  57--log[=<n>]::
  58--no-log::
  59        In addition to branch names, populate the log message with
  60        one-line descriptions from at most <n> actual commits that are being
  61        merged. See also linkgit:git-fmt-merge-msg[1].
  62+
  63With --no-log do not list one-line descriptions from the
  64actual commits being merged.
  65
  66--signoff::
  67--no-signoff::
  68        Add Signed-off-by line by the committer at the end of the commit
  69        log message.  The meaning of a signoff depends on the project,
  70        but it typically certifies that committer has
  71        the rights to submit this work under the same license and
  72        agrees to a Developer Certificate of Origin
  73        (see http://developercertificate.org/ for more information).
  74+
  75With --no-signoff do not add a Signed-off-by line.
  76
  77--stat::
  78-n::
  79--no-stat::
  80        Show a diffstat at the end of the merge. The diffstat is also
  81        controlled by the configuration option merge.stat.
  82+
  83With -n or --no-stat do not show a diffstat at the end of the
  84merge.
  85
  86--squash::
  87--no-squash::
  88        Produce the working tree and index state as if a real merge
  89        happened (except for the merge information), but do not actually
  90        make a commit, move the `HEAD`, or record `$GIT_DIR/MERGE_HEAD`
  91        (to cause the next `git commit` command to create a merge
  92        commit).  This allows you to create a single commit on top of
  93        the current branch whose effect is the same as merging another
  94        branch (or more in case of an octopus).
  95+
  96With --no-squash perform the merge and commit the result. This
  97option can be used to override --squash.
  98
  99-s <strategy>::
 100--strategy=<strategy>::
 101        Use the given merge strategy; can be supplied more than
 102        once to specify them in the order they should be tried.
 103        If there is no `-s` option, a built-in list of strategies
 104        is used instead ('git merge-recursive' when merging a single
 105        head, 'git merge-octopus' otherwise).
 106
 107-X <option>::
 108--strategy-option=<option>::
 109        Pass merge strategy specific option through to the merge
 110        strategy.
 111
 112--verify-signatures::
 113--no-verify-signatures::
 114        Verify that the tip commit of the side branch being merged is
 115        signed with a valid key, i.e. a key that has a valid uid: in the
 116        default trust model, this means the signing key has been signed by
 117        a trusted key.  If the tip commit of the side branch is not signed
 118        with a valid key, the merge is aborted.
 119
 120--summary::
 121--no-summary::
 122        Synonyms to --stat and --no-stat; these are deprecated and will be
 123        removed in the future.
 124
 125ifndef::git-pull[]
 126-q::
 127--quiet::
 128        Operate quietly. Implies --no-progress.
 129
 130-v::
 131--verbose::
 132        Be verbose.
 133
 134--progress::
 135--no-progress::
 136        Turn progress on/off explicitly. If neither is specified,
 137        progress is shown if standard error is connected to a terminal.
 138        Note that not all merge strategies may support progress
 139        reporting.
 140
 141endif::git-pull[]
 142
 143--allow-unrelated-histories::
 144        By default, `git merge` command refuses to merge histories
 145        that do not share a common ancestor.  This option can be
 146        used to override this safety when merging histories of two
 147        projects that started their lives independently. As that is
 148        a very rare occasion, no configuration variable to enable
 149        this by default exists and will not be added.
