41 .sp
42 .SH "DESCRIPTION"
43 .sp
44 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 \fIgit pull\fR to incorporate changes from another repository and can be used by hand to merge changes from one branch into another\&.
45 .sp
46 Assume the following history exists and the current branch is "\fBmaster\fR":
47 .sp
48 .if n \{\
49 .RS 4
50 .\}
51 .nf
52 A\-\-\-B\-\-\-C topic

55 .fi
56 .if n \{\
57 .RE
58 .\}
59 .sp
60 .sp
61 Then "\fBgit merge topic\fR" will replay the changes made on the \fBtopic\fR branch since it diverged from \fBmaster\fR (i\&.e\&., \fBE\fR) until its current commit (\fBC\fR) on top of \fBmaster\fR, 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\&.
62 .sp
63 .if n \{\

76 The second syntax ("\fBgit merge \-\-abort\fR") can only be run after the merge has resulted in conflicts\&. \fIgit merge \-\-abort\fR 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), \fIgit merge \-\-abort\fR will in some cases be unable to reconstruct the original (pre\-merge) changes\&. Therefore:
77 .sp
78 \fBWarning\fR: Running \fIgit merge\fR 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\&.
79 .sp
80 The third syntax ("\fBgit merge \-\-continue\fR") can only be run after the merge has resulted in conflicts\&.
81 .SH "OPTIONS"
82 .PP
83 \-\-commit, \-\-no\-commit
84 .RS 4
85 Perform the merge and commit the result\&. This option can be used to override \-\-no\-commit\&.
86 .sp
87 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\&.
88 .sp
89 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\&.
90 .RE
91 .PP
92 \-\-edit, \-e, \-\-no\-edit
93 .RS 4
94 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
95 \fB\-\-no\-edit\fR
96 option can be used to accept the auto\-generated message (this is generally discouraged)\&. The
97 \fB\-\-edit\fR
98 (or
99 \fB\-e\fR) option is still useful if you are giving a draft message with the
100 \fB\-m\fR
101 option from the command line and want to edit it in the editor\&.
102 .sp
103 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
104 \fBgit merge\fR\&. To make it easier to adjust such scripts to the updated behaviour, the environment variable
105 \fBGIT_MERGE_AUTOEDIT\fR
106 can be set to
107 \fBno\fR
108 at the beginning of them\&.
109 .RE
110 .PP
111 \-\-cleanup=<mode>
112 .RS 4
113 This option determines how the merge message will be cleaned up before committing\&. See
114 \fBgit-commit\fR(1)
115 for more details\&. In addition, if the
116 \fI<mode>\fR
117 is given a value of
118 \fBscissors\fR, scissors will be appended to
119 \fBMERGE_MSG\fR
120 before being passed on to the commit machinery in the case of a merge conflict\&.

123 \-\-ff, \-\-no\-ff, \-\-ff\-only

126 \fB\-\-ff\fR

128 \fBrefs/tags/\fR
129 hierarchy, in which case
130 \fB\-\-no\-ff\fR
131 is assumed\&.
132 .sp
133 With
134 \fB\-\-ff\fR, 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\&.
135 .sp

147 argument is optional and defaults to the committer identity; if specified, it must be stuck to the option without a space\&.
148 \fB\-\-no\-gpg\-sign\fR

164 .RS 4
165 Add a
166 \fBSigned\-off\-by\fR
167 trailer by the committer at the end of the commit log message\&. The meaning of a signoff depends on the project to which you\(cqre committing\&. For example, it may certify that the committer has the rights to submit the work under the project\(cqs license or agrees to some contributor representation, such as a Developer Certificate of Origin\&. (See
168 \m[blue]\fBhttp://developercertificate\&.org\fR\m[]

345 .RE
346 .SH "PRE\-MERGE CHECKS"
347 .sp
348 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 \fBgit-stash\fR(1)\&. \fIgit pull\fR and \fIgit merge\fR will stop without doing anything when local uncommitted changes overlap with files that \fIgit pull\fR/\fIgit merge\fR may need to update\&.
349 .sp
350 To avoid recording unrelated changes in the merge commit, \fIgit pull\fR and \fIgit merge\fR will also abort if there are any changes registered in the index relative to the \fBHEAD\fR commit\&. (Special narrow exceptions to this rule may exist depending on which merge strategy is in use, but generally, the index must match HEAD\&.)
351 .sp
352 If all named commits are already ancestors of \fBHEAD\fR, \fIgit merge\fR will exit early with the message "Already up to date\&."
353 .SH "FAST\-FORWARD MERGE"
354 .sp
355 Often the current branch head is an ancestor of the named commit\&. This is the most common case especially when invoked from \fIgit pull\fR: 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 \fBHEAD\fR (along with the index) is updated to point at the named commit, without creating an extra merge commit\&.

434 .SH "MERGING TAG"

436 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 \fBgit-tag\fR(1)\&.

Among the changes made to the common ancestor\(cqs 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\&.

Additionally this strategy can detect and handle merges involving renames\&. It does not make use of detected copies\&.
