   1 --commit::
   2 --no-commit::
   3         Perform the merge and commit the result. This option can
   4         be used to override --no-commit.
   5 +
   6 With --no-commit perform the merge but pretend the merge
   7 failed and do not autocommit, to give the user a chance to
   8 inspect 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).
  18 ifndef::git-pull[]
  19 The `--edit` (or `-e`) option is still useful if you are
  20 giving a draft message with the `-m` option from the command line
  21 and want to edit it in the editor.
  22 endif::git-pull[]
  23 +
  24 Older scripts may depend on the historical behaviour of not allowing the
  25 user to edit the merge log message. They will see an editor opened when
  26 they run `git merge`. To make it easier to adjust such scripts to the
  27 updated behaviour, the environment variable `GIT_MERGE_AUTOEDIT` can be
  28 set 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 +
  51 With --no-log do not list one-line descriptions from the
  52 actual 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 +
  61 With -n or --no-stat do not show a diffstat at the end of the
  62 merge.
  63
  64 --squash::
  65 --no-squash::
  66         Produce the working tree and index state as if a real merge
  67         happened (except for the merge information), but do not actually
  68         make a commit, move the `HEAD`, or record `$GIT_DIR/MERGE_HEAD`
  69         (to cause the next `git commit` command to create a merge
  70         commit).  This allows you to create a single commit on top of
  71         the current branch whose effect is the same as merging another
  72         branch (or more in case of an octopus).
  73 +
  74 With --no-squash perform the merge and commit the result. This
  75 option can be used to override --squash.
  76
  77 -s <strategy>::
  78 --strategy=<strategy>::
  79         Use the given merge strategy; can be supplied more than
  80         once to specify them in the order they should be tried.
  81         If there is no `-s` option, a built-in list of strategies
  82         is used instead ('git merge-recursive' when merging a single
  83         head, 'git merge-octopus' otherwise).
  84
  85 -X <option>::
  86 --strategy-option=<option>::
  87         Pass merge strategy specific option through to the merge
  88         strategy.
  89
  90 --verify-signatures::
  91 --no-verify-signatures::
  92         Verify that the commits being merged have good and trusted GPG signatures
  93         and abort the merge in case they do not.
  94
  95 --summary::
  96 --no-summary::
  97         Synonyms to --stat and --no-stat; these are deprecated and will be
  98         removed in the future.
  99
 100 ifndef::git-pull[]
 101 -q::
 102 --quiet::
 103         Operate quietly. Implies --no-progress.
 104
 105 -v::
 106 --verbose::
 107         Be verbose.
 108
 109 --progress::
 110 --no-progress::
 111         Turn progress on/off explicitly. If neither is specified,
 112         progress is shown if standard error is connected to a terminal.
 113         Note that not all merge strategies may support progress
 114         reporting.
 115
 116 endif::git-pull[]
 117
 118 --allow-unrelated-histories::
 119         By default, `git merge` command refuses to merge histories
 120         that do not share a common ancestor.  This option can be
 121         used to override this safety when merging histories of two
 122         projects that started their lives independently. As that is
 123         a very rare occasion, no configuration variable to enable
 124         this by default exists and will not be added.
