   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 but pretend the merge
   7failed and do not autocommit, to give the user a chance to
   8inspect and further tweak the merge result before committing.
   9
  10--edit::
  11-e::
  12--no-edit::
  13        Invoke an editor before committing successful mechanical merge to
  14        further edit the auto-generated merge message, so that the user
  15        can explain and justify the merge. The `--no-edit` option can be
  16        used to accept the auto-generated message (this is generally
  17        discouraged).
  18ifndef::git-pull[]
  19The `--edit` (or `-e`) option is still useful if you are
  20giving a draft message with the `-m` option from the command line
  21and want to edit it in the editor.

  23+
  24Older scripts may depend on the historical behaviour of not allowing the
  25user to edit the merge log message. They will see an editor opened when
  26they run `git merge`. To make it easier to adjust such scripts to the
  27updated behaviour, the environment variable `GIT_MERGE_AUTOEDIT` can be
  28set to `no` at the beginning of them.
  29
  30--ff::
  31        When the merge resolves as a fast-forward, only update the branch
  32        pointer, without creating a merge commit.  This is the default
  33        behavior.
  34
  35--no-ff::
  36        Create a merge commit even when the merge resolves as a
  37        fast-forward.  This is the default behaviour when merging an
  38        annotated (and possibly signed) tag.
  39
  40--ff-only::
  41        Refuse to merge and exit with a non-zero status unless the
  42        current `HEAD` is already up-to-date or the merge can be
  43        resolved as a fast-forward.
  44
  45--log[=<n>]::
  46--no-log::
  47        In addition to branch names, populate the log message with
  48        one-line descriptions from at most <n> actual commits that are being
  49        merged. See also linkgit:git-fmt-merge-msg[1].
  50+
  51With --no-log do not list one-line descriptions from the
  52actual commits being merged.
  53
  54
  55--stat::
  56-n::
  57--no-stat::
  58        Show a diffstat at the end of the merge. The diffstat is also
  59        controlled by the configuration option merge.stat.
  60+
  61With -n or --no-stat do not show a diffstat at the end of the
  62merge.
  63
  64--squash::
  65--no-squash::
  66        Produce the working tree and index state as if a real
  67        merge happened (except for the merge information),
  68        but do not actually make a commit or
  69        move the `HEAD`, nor record `$GIT_DIR/MERGE_HEAD` to
  70        cause the next `git commit` command to create a merge
  71        commit.  This allows you to create a single commit on
  72        top of the current branch whose effect is the same as
  73        merging another branch (or more in case of an octopus).
  74+
  75With --no-squash perform the merge and commit the result. This
  76option can be used to override --squash.
  77
  78-s <strategy>::
  79--strategy=<strategy>::
  80        Use the given merge strategy; can be supplied more than
  81        once to specify them in the order they should be tried.
  82        If there is no `-s` option, a built-in list of strategies
  83        is used instead ('git merge-recursive' when merging a single
  84        head, 'git merge-octopus' otherwise).
  85
  86-X <option>::
  87--strategy-option=<option>::
  88        Pass merge strategy specific option through to the merge
  89        strategy.
  90
  91--verify-signatures::
  92--no-verify-signatures::
  93        Verify that the commits being merged have good and trusted GPG signatures
  94        and abort the merge in case they do not.
  95
  96--summary::
  97--no-summary::
  98        Synonyms to --stat and --no-stat; these are deprecated and will be
  99        removed in the future.
 100
 101ifndef::git-pull[]
 102-q::
 103--quiet::
 104        Operate quietly. Implies --no-progress.
 105
 106-v::
 107--verbose::
 108        Be verbose.
 109
 110--progress::
 111--no-progress::
 112        Turn progress on/off explicitly. If neither is specified,
 113        progress is shown if standard error is connected to a terminal.
 114        Note that not all merge strategies may support progress
 115        reporting.
