Perform the merge and commit the result. This option can
be used to override --no-commit.
With --no-commit perform the merge and stop just before creating
a merge commit, to give the user a chance to inspect and further
tweak the merge result before committing.
Note that fast-forward updates do not create a merge commit and
therefore there is no way to stop those merges with --no-commit.
Thus, if you want to ensure your branch is not changed or updated
by the merge command, use --no-ff with --no-commit.
Invoke an editor before committing successful mechanical merge to
further edit the auto-generated merge message, so that the user
can explain and justify the merge. The `--no-edit` option can be
used to accept the auto-generated message (this is generally
The `--edit` (or `-e`) option is still useful if you are
giving a draft message with the `-m` option from the command line
and want to edit it in the editor.
Older scripts may depend on the historical behaviour of not allowing the
user to edit the merge log message. They will see an editor opened when
they run `git merge`. To make it easier to adjust such scripts to the
updated behaviour, the environment variable `GIT_MERGE_AUTOEDIT` can be
set to `no` at the beginning of them.
When the merge resolves as a fast-forward, only update the branch
pointer, without creating a merge commit. This is the default
Create a merge commit even when the merge resolves as a
fast-forward. This is the default behaviour when merging an
annotated (and possibly signed) tag that is not stored in
its natural place in 'refs/tags/' hierarchy.
Refuse to merge and exit with a non-zero status unless the
current `HEAD` is already up to date or the merge can be
resolved as a fast-forward.
GPG-sign the resulting merge commit. The `keyid` argument is
optional and defaults to the committer identity; if specified,
it must be stuck to the option without a space.
In addition to branch names, populate the log message with
one-line descriptions from at most <n> actual commits that are being
merged. See also linkgit:git-fmt-merge-msg.
With --no-log do not list one-line descriptions from the
actual commits being merged.
Add Signed-off-by line by the committer at the end of the commit
log message. The meaning of a signoff depends on the project,
but it typically certifies that committer has
the rights to submit this work under the same license and
agrees to a Developer Certificate of Origin
(see http://developercertificate.org/ for more information).
With --no-signoff do not add a Signed-off-by line.
Show a diffstat at the end of the merge. The diffstat is also
controlled by the configuration option merge.stat.
With -n or --no-stat do not show a diffstat at the end of the
Produce the working tree and index state as if a real merge
happened (except for the merge information), but do not actually
make a commit, move the `HEAD`, or record `$GIT_DIR/MERGE_HEAD`
(to cause the next `git commit` command to create a merge
commit). This allows you to create a single commit on top of
the current branch whose effect is the same as merging another
branch (or more in case of an octopus).
With --no-squash perform the merge and commit the result. This
option can be used to override --squash.
With --squash, a --commit option does not make sense, and will be ignored
(HEAD will not be moved in spite of --commit).
Use the given merge strategy; can be supplied more than
once to specify them in the order they should be tried.
If there is no `-s` option, a built-in list of strategies
is used instead ('git merge-recursive' when merging a single
head, 'git merge-octopus' otherwise).
Pass merge strategy specific option through to the merge
Verify that the tip commit of the side branch being merged is
signed with a valid key, i.e. a key that has a valid uid: in the
default trust model, this means the signing key has been signed by
a trusted key. If the tip commit of the side branch is not signed
with a valid key, the merge is aborted.
Synonyms to --stat and --no-stat; these are deprecated and will be
removed in the future.
Operate quietly. Implies --no-progress.
Turn progress on/off explicitly. If neither is specified,
progress is shown if standard error is connected to a terminal.
Note that not all merge strategies may support progress
By default, `git merge` command refuses to merge histories
that do not share a common ancestor. This option can be
used to override this safety when merging histories of two
projects that started their lives independently. As that is
a very rare occasion, no configuration variable to enable
this by default exists and will not be added.
