 NAME
 ----
 git-merge - Join two or more development histories together


 SYNOPSIS
 --------
 [verse]
 'git merge' [-n] [--stat] [--no-commit] [--squash] [--[no-]edit]
 	[--no-verify] [-s <strategy>] [-X <strategy-option>] [-S[<keyid>]]
 	[--[no-]allow-unrelated-histories]
 	[--[no-]rerere-autoupdate] [-m <msg>] [-F <file>] [<commit>...]
 'git merge' (--continue | --abort | --quit)

 DESCRIPTION
 -----------
 Incorporates changes from the named commits (since the time their
 histories diverged from the current branch) into the current
 branch.  This command is used by 'git pull' to incorporate changes
 from another repository and can be used by hand to merge changes
 from one branch into another.

 Assume the following history exists and the current branch is
 "`master`":

 ------------
 	  A---B---C topic
 	 /
     D---E---F---G master
 ------------

 Then "`git merge topic`" will replay the changes made on the
 `topic` branch since it diverged from `master` (i.e., `E`) until
 its current commit (`C`) on top of `master`, and record the result
 in a new commit along with the names of the two parent commits and
 a log message from the user describing the changes.

 ------------
 	  A---B---C topic
 	 /         \
     D---E---F---G---H master
 ------------

 The second syntax ("`git merge --abort`") can only be run after the
 merge has resulted in conflicts. 'git merge --abort' will abort the
 merge process and try to reconstruct the pre-merge state. However,
 if there were uncommitted changes when the merge started (and
 especially if those changes were further modified after the merge
 was started), 'git merge --abort' will in some cases be unable to
 reconstruct the original (pre-merge) changes. Therefore:

 *Warning*: Running 'git merge' with non-trivial uncommitted changes is
 discouraged: while possible, it may leave you in a state that is hard to
 back out of in the case of a conflict.

 The third syntax ("`git merge --continue`") can only be run after the
 merge has resulted in conflicts.

 OPTIONS
 -------
 include::merge-options.txt[]

 -m <msg>::
 	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 merge'
 invocations. The automated message can include the branch description.

 -F <file>::
 --file=<file>::
 	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.

 --rerere-autoupdate::
 --no-rerere-autoupdate::
 	Allow the rerere mechanism to update the index with the
 	result of auto-conflict resolution if possible.

 --overwrite-ignore::
 --no-overwrite-ignore::
 	Silently overwrite ignored files from the merge result. This
 	is the default behavior. Use `--no-overwrite-ignore` to abort.

 --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' when
 `MERGE_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.

 --quit::
 	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.

 --continue::
 	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).

 <commit>...::
 	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.


 PRE-MERGE CHECKS
 ----------------

 Before applying outside changes, you should get your own work in
 good shape and committed locally, so it will not be clobbered if
 there are conflicts.  See also linkgit:git-stash[1].
 'git pull' and 'git merge' will stop without doing anything when
 local uncommitted changes overlap with files that 'git pull'/'git
 merge' may need to update.

 To avoid recording unrelated changes in the merge commit,
 'git pull' and 'git merge' will also abort if there are any changes
 registered in the index relative to the `HEAD` commit.  (Special
 narrow exceptions to this rule may exist depending on which merge
 strategy is in use, but generally, the index must match HEAD.)

 If all named commits are already ancestors of `HEAD`, 'git merge'
 will exit early with the message "Already up to date."

 FAST-FORWARD MERGE
 ------------------

 Often the current branch head is an ancestor of the named commit.
 This is the most common case especially when invoked from 'git
 pull': you are tracking an upstream repository, you have committed
 no local changes, and now you want to update to a newer upstream
 revision.  In this case, a new commit is not needed to store the
 combined history; instead, the `HEAD` (along with the index) is
 updated to point at the named commit, without creating an extra
 merge commit.

 This behavior can be suppressed with the `--no-ff` option.

 TRUE MERGE
 ----------

 Except in a fast-forward merge (see above), the branches to be
 merged must be tied together by a merge commit that has both of them
 as its parents.

 A merged version reconciling the changes from all branches to be
 merged is committed, and your `HEAD`, index, and working tree are
 updated to it.  It is possible to have modifications in the working
 tree as long as they do not overlap; the update will preserve them.

 When it is not obvious how to reconcile the changes, the following
 happens:

 1. The `HEAD` pointer stays the same.
 2. The `MERGE_HEAD` ref is set to point to the other branch head.
 3. Paths that merged cleanly are updated both in the index file and
    in your working tree.
 4. For conflicting paths, the index file records up to three
    versions: stage 1 stores the version from the common ancestor,
    stage 2 from `HEAD`, and stage 3 from `MERGE_HEAD` (you
    can inspect the stages with `git ls-files -u`).  The working
    tree files contain the result of the "merge" program; i.e. 3-way
    merge results with familiar conflict markers `<<<` `===` `>>>`.
 5. No other changes are made.  In particular, the local
    modifications you had before you started merge will stay the
    same and the index entries for them stay as they were,
    i.e. matching `HEAD`.

 If you tried a merge which resulted in complex conflicts and
 want to start over, you can recover with `git merge --abort`.

 MERGING TAG
 -----------

 When merging an annotated (and possibly signed) tag, Git always
 creates a merge commit even if a fast-forward merge is possible, and
 the commit message template is prepared with the tag message.
 Additionally, if the tag is signed, the signature check is reported
 as a comment in the message template. See also linkgit:git-tag[1].

 When you want to just integrate with the work leading to the commit
 that happens to be tagged, e.g. synchronizing with an upstream
 release point, you may not want to make an unnecessary merge commit.

 In such a case, you can "unwrap" the tag yourself before feeding it
 to `git merge`, or pass `--ff-only` when you do not have any work on
 your own. e.g.

 ----
 git fetch origin
 git merge v1.2.3^0
 git merge --ff-only v1.2.3
 ----


 HOW CONFLICTS ARE PRESENTED
 ---------------------------

 During a merge, the working tree files are updated to reflect the result
 of the merge.  Among the changes made to the common ancestor's version,
 non-overlapping ones (that is, you changed an area of the file while the
 other side left that area intact, or vice versa) are incorporated in the
 final result verbatim.  When both sides made changes to the same area,
 however, Git cannot randomly pick one side over the other, and asks you to
 resolve it by leaving what both sides did to that area.

 By default, Git uses the same style as the one used by the "merge" program
 from the RCS suite to present such a conflicted hunk, like this:

 ------------
 Here are lines that are either unchanged from the common
 ancestor, or cleanly resolved because only one side changed.
 <<<<<<< yours:sample.txt
 Conflict resolution is hard;
 let's go shopping.
 =======
 Git makes conflict resolution easy.
 >>>>>>> theirs:sample.txt
 And here is another line that is cleanly resolved or unmodified.
 ------------

 The area where a pair of conflicting changes happened is marked with markers
 `<<<<<<<`, `=======`, and `>>>>>>>`.  The part before the `=======`
 is typically your side, and the part afterwards is typically their side.

 The default format does not show what the original said in the conflicting
 area.  You cannot tell how many lines are deleted and replaced with
 Barbie's remark on your side.  The only thing you can tell is that your
 side wants to say it is hard and you'd prefer to go shopping, while the
 other side wants to claim it is easy.

 An alternative style can be used by setting the "merge.conflictStyle"
 configuration variable to "diff3".  In "diff3" style, the above conflict
 may look like this:

 ------------
 Here are lines that are either unchanged from the common
 ancestor, or cleanly resolved because only one side changed.
 <<<<<<< yours:sample.txt
 Conflict resolution is hard;
 let's go shopping.
 |||||||
 Conflict resolution is hard.
 =======
 Git makes conflict resolution easy.
 >>>>>>> theirs:sample.txt
 And here is another line that is cleanly resolved or unmodified.
 ------------

 In addition to the `<<<<<<<`, `=======`, and `>>>>>>>` markers, it uses
 another `|||||||` marker that is followed by the original text.  You can
 tell that the original just stated a fact, and your side simply gave in to
 that statement and gave up, while the other side tried to have a more
 positive attitude.  You can sometimes come up with a better resolution by
 viewing the original.


 HOW TO RESOLVE CONFLICTS
 ------------------------

 After seeing a conflict, you can do two things:

  * Decide not to merge.  The only clean-ups you need are to reset
    the index file to the `HEAD` commit to reverse 2. and to clean
    up working tree changes made by 2. and 3.; `git merge --abort`
    can be used for this.

  * Resolve the conflicts.  Git will mark the conflicts in
    the working tree.  Edit the files into shape and
    'git add' them to the index.  Use 'git commit' or
    'git merge --continue' to seal the deal. The latter command
    checks whether there is a (interrupted) merge in progress
    before calling 'git commit'.

 You can work through the conflict with a number of tools:

  * Use a mergetool.  `git mergetool` to launch a graphical
    mergetool which will work you through the merge.

  * Look at the diffs.  `git diff` will show a three-way diff,
    highlighting changes from both the `HEAD` and `MERGE_HEAD`
    versions.

  * Look at the diffs from each branch. `git log --merge -p <path>`
    will show diffs first for the `HEAD` version and then the
    `MERGE_HEAD` version.

  * Look at the originals.  `git show :1:filename` shows the
    common ancestor, `git show :2:filename` shows the `HEAD`
    version, and `git show :3:filename` shows the `MERGE_HEAD`
    version.


 EXAMPLES
 --------

 * Merge branches `fixes` and `enhancements` on top of
   the current branch, making an octopus merge:
 +
 ------------------------------------------------
 $ git merge fixes enhancements
 ------------------------------------------------

 * Merge branch `obsolete` into the current branch, using `ours`
   merge strategy:
 +
 ------------------------------------------------
 $ git merge -s ours obsolete
 ------------------------------------------------

 * Merge branch `maint` into the current branch, but do not make
   a new commit automatically:
 +
 ------------------------------------------------
 $ git merge --no-commit maint
 ------------------------------------------------
 +
 This can be used when you want to include further changes to the
 merge, or want to write your own merge commit message.
 +
 You should refrain from abusing this option to sneak substantial
 changes into a merge commit.  Small fixups like bumping
 release/version name would be acceptable.
