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.

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
08f19cfe

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.

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.

1055997e 36 This option determines how the merge message will be cleaned up before
031fd4b9 37 committing. See linkgit:git-commit[1] for more details. In addition, if
1055997e
DL
38 the '<mode>' is given a value of `scissors`, scissors will be appended
39 to `MERGE_MSG` before being passed on to the commit machinery in the
40 case of a merge conflict.

42--ff::
43--no-ff::
690b2975 44--ff-only::

EN
45 Specifies how a merge is handled when the merged-in history is
46 already a descendant of the current history. `--ff` is the
47 default unless merging an annotated (and possibly signed) tag
48 that is not stored in its natural place in the `refs/tags/`
49 hierarchy, in which case `--no-ff` is assumed.
50+
51With `--ff`, when possible resolve the merge as a fast-forward (only
52update the branch pointer to match the merged branch; do not create a
53merge commit). When not possible (when the merged-in history is not a
54descendant of the current history), create a merge commit.
55+
56With `--no-ff`, create a merge commit in all cases, even when the merge
57could instead be resolved as a fast-forward.
58+
59With `--ff-only`, resolve the merge as a fast-forward when possible.
60When not possible, refuse to merge and exit with a non-zero status.

93 Produce the working tree and index state as if a real merge
94 happened (except for the merge information), but do not actually
95 make a commit, move the `HEAD`, or record `$GIT_DIR/MERGE_HEAD`
96 (to cause the next `git commit` command to create a merge
97 commit). This allows you to create a single commit on top of
98 the current branch whose effect is the same as merging another
99 branch (or more in case of an octopus).

125 Verify that the tip commit of the side branch being merged is
126 signed with a valid key, i.e. a key that has a valid uid: in the
127 default trust model, this means the signing key has been signed by
128 a trusted key. If the tip commit of the side branch is not signed
129 with a valid key, the merge is aborted.

154--autostash::
155--no-autostash::
156 Automatically create a temporary stash entry before the operation
157 begins, and apply it after the operation ends. This means
158 that you can run the operation on a dirty worktree. However, use
159 with care: the final stash application after a successful
160 merge might result in non-trivial conflicts.

162--allow-unrelated-histories::
163 By default, `git merge` command refuses to merge histories
164 that do not share a common ancestor. This option can be
165 used to override this safety when merging histories of two
166 projects that started their lives independently. As that is
167 a very rare occasion, no configuration variable to enable
168 this by default exists and will not be added.
