3 Perform the merge and commit the result. This option can
4 be used to override --no-commit.
6 With --no-commit perform the merge and stop just before creating
7 a merge commit, to give the user a chance to inspect and further
8 tweak the merge result before committing.
10 Note that fast-forward updates do not create a merge commit and
11 therefore there is no way to stop those merges with --no-commit.
12 Thus, if you want to ensure your branch is not changed or updated
13 by the merge command, use --no-ff with --no-commit.
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
24 The `--edit` (or `-e`) option is still useful if you are
25 giving a draft message with the `-m` option from the command line
26 and want to edit it in the editor.
29 Older scripts may depend on the historical behaviour of not allowing the
30 user to edit the merge log message. They will see an editor opened when
31 they run `git merge`. To make it easier to adjust such scripts to the
32 updated behaviour, the environment variable `GIT_MERGE_AUTOEDIT` can be
33 set to `no` at the beginning of them.
36 This option determines how the merge message will be cleaned up before
37 commiting. See linkgit:git-commit[1] for more details. In addition, if
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.
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.
51 With `--ff`, when possible resolve the merge as a fast-forward (only
52 update the branch pointer to match the merged branch; do not create a
53 merge commit). When not possible (when the merged-in history is not a
54 descendant of the current history), create a merge commit.
56 With `--no-ff`, create a merge commit in all cases, even when the merge
57 could instead be resolved as a fast-forward.
59 With `--ff-only`, resolve the merge as a fast-forward when possible.
60 When not possible, refuse to merge and exit with a non-zero status.
63 --gpg-sign[=<keyid>]::
64 GPG-sign the resulting merge commit. The `keyid` argument is
65 optional and defaults to the committer identity; if specified,
66 it must be stuck to the option without a space.
70 In addition to branch names, populate the log message with
71 one-line descriptions from at most <n> actual commits that are being
72 merged. See also linkgit:git-fmt-merge-msg[1].
74 With --no-log do not list one-line descriptions from the
75 actual commits being merged.
79 Add Signed-off-by line by the committer at the end of the commit
80 log message. The meaning of a signoff depends on the project,
81 but it typically certifies that committer has
82 the rights to submit this work under the same license and
83 agrees to a Developer Certificate of Origin
84 (see http://developercertificate.org/ for more information).
86 With --no-signoff do not add a Signed-off-by line.
91 Show a diffstat at the end of the merge. The diffstat is also
92 controlled by the configuration option merge.stat.
94 With -n or --no-stat do not show a diffstat at the end of the
99 Produce the working tree and index state as if a real merge
100 happened (except for the merge information), but do not actually
101 make a commit, move the `HEAD`, or record `$GIT_DIR/MERGE_HEAD`
102 (to cause the next `git commit` command to create a merge
103 commit). This allows you to create a single commit on top of
104 the current branch whose effect is the same as merging another
105 branch (or more in case of an octopus).
107 With --no-squash perform the merge and commit the result. This
108 option can be used to override --squash.
110 With --squash, --commit is not allowed, and will fail.
113 This option bypasses the pre-merge and commit-msg hooks.
114 See also linkgit:githooks[5].
117 --strategy=<strategy>::
118 Use the given merge strategy; can be supplied more than
119 once to specify them in the order they should be tried.
120 If there is no `-s` option, a built-in list of strategies
121 is used instead ('git merge-recursive' when merging a single
122 head, 'git merge-octopus' otherwise).
125 --strategy-option=<option>::
126 Pass merge strategy specific option through to the merge
129 --verify-signatures::
130 --no-verify-signatures::
131 Verify that the tip commit of the side branch being merged is
132 signed with a valid key, i.e. a key that has a valid uid: in the
133 default trust model, this means the signing key has been signed by
134 a trusted key. If the tip commit of the side branch is not signed
135 with a valid key, the merge is aborted.
139 Synonyms to --stat and --no-stat; these are deprecated and will be
140 removed in the future.
145 Operate quietly. Implies --no-progress.
153 Turn progress on/off explicitly. If neither is specified,
154 progress is shown if standard error is connected to a terminal.
155 Note that not all merge strategies may support progress
160 --allow-unrelated-histories::
161 By default, `git merge` command refuses to merge histories
162 that do not share a common ancestor. This option can be
163 used to override this safety when merging histories of two
164 projects that started their lives independently. As that is
165 a very rare occasion, no configuration variable to enable
166 this by default exists and will not be added.
