1--commit:: 2--no-commit:: 3 Perform the merge and commit the result. This option can 4 be used to override --no-commit. 5+ 6With --no-commit perform the merge but pretend the merge 7failed and do not autocommit, to give the user a chance to 8inspect and further tweak the merge result before committing. 9 10--edit:: 11-e:: 12--no-edit:: 13 Invoke an editor before committing successful mechanical merge to 14 further edit the auto-generated merge message, so that the user 15 can explain and justify the merge. The `--no-edit` option can be 16 used to accept the auto-generated message (this is generally 17 discouraged). 18ifndef::git-pull[] 19The `--edit` (or `-e`) option is still useful if you are 20giving a draft message with the `-m` option from the command line 21and want to edit it in the editor. 22endif::git-pull[] 23+ 24Older scripts may depend on the historical behaviour of not allowing the 25user to edit the merge log message. They will see an editor opened when 26they run `git merge`. To make it easier to adjust such scripts to the 27updated behaviour, the environment variable `GIT_MERGE_AUTOEDIT` can be 28set to `no` at the beginning of them. 29 30--ff:: 31 When the merge resolves as a fast-forward, only update the branch 32 pointer, without creating a merge commit. This is the default 33 behavior. 34 35--no-ff:: 36 Create a merge commit even when the merge resolves as a 37 fast-forward. This is the default behaviour when merging an 38 annotated (and possibly signed) tag. 39 40--ff-only:: 41 Refuse to merge and exit with a non-zero status unless the 42 current `HEAD` is already up to date or the merge can be 43 resolved as a fast-forward. 44 45--log[=<n>]:: 46--no-log:: 47 In addition to branch names, populate the log message with 48 one-line descriptions from at most <n> actual commits that are being 49 merged. See also linkgit:git-fmt-merge-msg[1]. 50+ 51With --no-log do not list one-line descriptions from the 52actual commits being merged. 53 54--signoff:: 55--no-signoff:: 56 Add Signed-off-by line by the committer at the end of the commit 57 log message. The meaning of a signoff depends on the project, 58 but it typically certifies that committer has 59 the rights to submit this work under the same license and 60 agrees to a Developer Certificate of Origin 61 (see http://developercertificate.org/ for more information). 62+ 63With --no-signoff do not add a Signed-off-by line. 64 65--stat:: 66-n:: 67--no-stat:: 68 Show a diffstat at the end of the merge. The diffstat is also 69 controlled by the configuration option merge.stat. 70+ 71With -n or --no-stat do not show a diffstat at the end of the 72merge. 73 74--squash:: 75--no-squash:: 76 Produce the working tree and index state as if a real merge 77 happened (except for the merge information), but do not actually 78 make a commit, move the `HEAD`, or record `$GIT_DIR/MERGE_HEAD` 79 (to cause the next `git commit` command to create a merge 80 commit). This allows you to create a single commit on top of 81 the current branch whose effect is the same as merging another 82 branch (or more in case of an octopus). 83+ 84With --no-squash perform the merge and commit the result. This 85option can be used to override --squash. 86 87-s <strategy>:: 88--strategy=<strategy>:: 89 Use the given merge strategy; can be supplied more than 90 once to specify them in the order they should be tried. 91 If there is no `-s` option, a built-in list of strategies 92 is used instead ('git merge-recursive' when merging a single 93 head, 'git merge-octopus' otherwise). 94 95-X <option>:: 96--strategy-option=<option>:: 97 Pass merge strategy specific option through to the merge 98 strategy. 99 100--verify-signatures:: 101--no-verify-signatures:: 102 Verify that the tip commit of the side branch being merged is 103 signed with a valid key, i.e. a key that has a valid uid: in the 104 default trust model, this means the signing key has been signed by 105 a trusted key. If the tip commit of the side branch is not signed 106 with a valid key, the merge is aborted. 107 108--summary:: 109--no-summary:: 110 Synonyms to --stat and --no-stat; these are deprecated and will be 111 removed in the future. 112 113ifndef::git-pull[] 114-q:: 115--quiet:: 116 Operate quietly. Implies --no-progress. 117 118-v:: 119--verbose:: 120 Be verbose. 121 122--progress:: 123--no-progress:: 124 Turn progress on/off explicitly. If neither is specified, 125 progress is shown if standard error is connected to a terminal. 126 Note that not all merge strategies may support progress 127 reporting. 128 129endif::git-pull[] 130 131--allow-unrelated-histories:: 132 By default, `git merge` command refuses to merge histories 133 that do not share a common ancestor. This option can be 134 used to override this safety when merging histories of two 135 projects that started their lives independently. As that is 136 a very rare occasion, no configuration variable to enable 137 this by default exists and will not be added.
