--commit:: --no-commit:: Perform the merge and commit the result. This option can be used to override --no-commit. + With --no-commit perform the merge but pretend the merge failed and do not autocommit, to give the user a chance to inspect and further tweak the merge result before committing. --edit:: -e:: --no-edit:: 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 discouraged). ifndef::git-pull[] 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. endif::git-pull[] + 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. --ff:: When the merge resolves as a fast-forward, only update the branch pointer, without creating a merge commit. This is the default behavior. --no-ff:: 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. --ff-only:: 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. -S[<keyid>]:: --gpg-sign[=<keyid>]:: 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. --log[=<n>]:: --no-log:: 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[1]. + With --no-log do not list one-line descriptions from the actual commits being merged. --signoff:: --no-signoff:: 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. --stat:: -n:: --no-stat:: 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 merge. --squash:: --no-squash:: 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. -s <strategy>:: --strategy=<strategy>:: 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). -X <option>:: --strategy-option=<option>:: Pass merge strategy specific option through to the merge strategy. --verify-signatures:: --no-verify-signatures:: 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. --summary:: --no-summary:: Synonyms to --stat and --no-stat; these are deprecated and will be removed in the future. ifndef::git-pull[] -q:: --quiet:: Operate quietly. Implies --no-progress. -v:: --verbose:: Be verbose. --progress:: --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 reporting. endif::git-pull[] --allow-unrelated-histories:: 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.
