Git - git-merge Documentation (original) (raw)
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 discouraged). 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.
This option determines how the merge message will be cleaned up before committing. See git-commit[1] for more details. In addition, if the is given a value of scissors, scissors will be appended to MERGE_MSG before being passed on to the commit machinery in the case of a merge conflict.
Specifies how a merge is handled when the merged-in history is already a descendant of the current history. --ff is the default unless merging an annotated (and possibly signed) tag that is not stored in its natural place in the refs/tags/hierarchy, in which case --no-ff is assumed.
With --ff, when possible resolve the merge as a fast-forward (only update the branch pointer to match the merged branch; do not create a merge commit). When not possible (when the merged-in history is not a descendant of the current history), create a merge commit.
With --no-ff, create a merge commit in all cases, even when the merge could instead be resolved as a fast-forward.
With --ff-only, resolve the merge as a fast-forward when possible. When not possible, refuse to merge and exit with a non-zero status.
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. --no-gpg-signis useful to countermand both commit.gpgSign configuration variable, and earlier --gpg-sign.
In addition to branch names, populate the log message with one-line descriptions from at most actual commits that are being merged. See also git-fmt-merge-msg[1].
With --no-log do not list one-line descriptions from the actual commits being merged.
Add a Signed-off-by trailer by the committer at the end of the commit log message. The meaning of a signoff depends on the project to which you’re committing. For example, it may certify that the committer has the rights to submit the work under the project’s license or agrees to some contributor representation, such as a Developer Certificate of Origin. (See https://developercertificate.org for the one used by the Linux kernel and Git projects.) Consult the documentation or leadership of the project to which you’re contributing to understand how the signoffs are used in that project.
The --no-signoff option can be used to countermand an earlier --signoffoption on the command 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 merge.
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, --commit is not allowed, and will fail.
By default, the pre-merge and commit-msg hooks are run. When --no-verify is given, these are bypassed. See also githooks[5].
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 (ort when merging a single head,octopus otherwise).
Pass merge strategy specific option through to the merge strategy.
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.
Be verbose.
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.
Automatically create a temporary stash entry before the operation begins, record it in the ref MERGE_AUTOSTASHand apply it after the operation ends. This means that you can run the operation on a dirty worktree. However, use with care: the final stash application after a successful merge might result in non-trivial conflicts.
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.
Set the commit message to be used for the merge commit (in case one is created).
If --log is specified, a shortlog of the commits being merged will be appended to the specified message.
The git fmt-merge-msg command can be used to give a good default for automated git mergeinvocations. The automated message can include the branch description.
Prepare the default merge message as if merging to the branch<branch>, instead of the name of the real branch to which the merge is made.
Read the commit message to be used for the merge commit (in case one is created).
If --log is specified, a shortlog of the commits being merged will be appended to the specified message.
After the rerere mechanism reuses a recorded resolution on the current conflict to update the files in the working tree, allow it to also update the index with the result of resolution. --no-rerere-autoupdate is a good way to double-check what rerere did and catch potential mismerges, before committing the result to the index with a separate git add.
Silently overwrite ignored files from the merge result. This is the default behavior. Use --no-overwrite-ignore to abort.
Abort the current conflict resolution process, and try to reconstruct the pre-merge state. If an autostash entry is present, apply it to the worktree.
If there were uncommitted worktree changes present when the merge started, git merge --abort will in some cases be unable to reconstruct these changes. It is therefore recommended to always commit or stash your changes before running git merge.
git merge --abort is equivalent to git reset --merge whenMERGE_HEAD is present unless MERGE_AUTOSTASH is also present in which case git merge --abort applies the stash entry to the worktree whereas git reset --merge will save the stashed changes in the stash list.
Forget about the current merge in progress. Leave the index and the working tree as-is. If MERGE_AUTOSTASH is present, the stash entry will be saved to the stash list.
After a git merge stops due to conflicts you can conclude the merge by running git merge --continue (see "HOW TO RESOLVE CONFLICTS" section below).
Commits, usually other branch heads, to merge into our branch. Specifying more than one commit will create a merge with more than two parents (affectionately called an Octopus merge).
If no commit is given from the command line, merge the remote-tracking branches that the current branch is configured to use as its upstream. See also the configuration section of this manual page.
When FETCH_HEAD (and no other commit) is specified, the branches recorded in the .git/FETCH_HEAD file by the previous invocation of git fetch for merging are merged to the current branch.
