If you do not 30 supply this argument, reads from the standard input. If you supply 31 directories, they'll be treated as Maildirs. 32 33-s:: 34--signoff:: 35 Add `Signed-off-by:` line to the commit message, using 36 the committer identity of yourself. 37 38-k:: 39--keep:: 40 Pass `-k` flag to 'git-mailinfo' (see linkgit:git-mailinfo[1]). 41 42-u:: 43--utf8:: 44 Pass `-u` flag to 'git-mailinfo' (see linkgit:git-mailinfo[1]). 45 The proposed commit log message taken from the e-mail 46 is re-coded into UTF-8 encoding (configuration variable 47 `i18n.commitencoding` can be used to specify project's 48 preferred encoding if it is not UTF-8). 49+ 50This was optional in prior versions of git, but now it is the 51default. You could use `--no-utf8` to override this. 52 53--no-utf8:: 54 Pass `-n` flag to 'git-mailinfo' (see 55 linkgit:git-mailinfo[1]). 56 57-3:: 58--3way:: 59 When the patch does not apply cleanly, fall back on 60 3-way merge, if the patch records the identity of blobs 61 it is supposed to apply to, and we have those blobs 62 available locally. 63 64--whitespace=<option>:: 65-C<n>:: 66-p<n>:: 67--directory=<dir>:: 68--reject:: 69 These flags are passed to the 'git-apply' (see linkgit:git-apply[1]) 70 program that applies 71 the patch. 72 73-i:: 74--interactive:: 75 Run interactively. 76 77--committer-date-is-author-date:: 78 By default the command records the date from the e-mail 79 message as the commit author date, and uses the time of 80 commit creation as the committer date. This allows the 81 user to lie about the committer date by using the same 82 timestamp as the author date. 83 84--ignore-date:: 85 By default the command records the date from the e-mail 86 message as the commit author date, and uses the time of 87 commit creation as the committer date. This allows the 88 user to lie about author timestamp by using the same 89 timestamp as the committer date. 90 91--skip:: 92 Skip the current patch. This is only meaningful when 93 restarting an aborted patch. 94 95-r:: 96--resolved:: 97 After a patch failure (e.g. attempting to apply 98 conflicting patch), the user has applied it by hand and 99 the index file stores the result of the application. 100 Make a commit using the authorship and commit log 101 extracted from the e-mail message and the current index 102 file, and continue. 103 104--resolvemsg=<msg>:: 105 When a patch failure occurs, <msg> will be printed 106 to the screen before exiting. This overrides the 107 standard message informing you to use `--resolved` 108 or `--skip` to handle the failure. This is solely 109 for internal use between 'git-rebase' and 'git-am'. 110 111--abort:: 112 Restore the original branch and abort the patching operation. 113 114DISCUSSION 115---------- 116 117The commit author name is taken from the "From: " line of the 118message, and commit author time is taken from the "Date: " line 119of the message. The "Subject: " line is used as the title of 120the commit, after stripping common prefix "[PATCH <anything>]". 121It is supposed to describe what the commit is about concisely as 122a one line text. 123 124The body of the message (iow, after a blank line that terminates 125RFC2822 headers) can begin with "Subject: " and "From: " lines 126that are different from those of the mail header, to override 127the values of these fields. 128 129The commit message is formed by the title taken from the 130"Subject: ", a blank line and the body of the message up to 131where the patch begins. Excess whitespaces at the end of the 132lines are automatically stripped. 133 134The patch is expected to be inline, directly following the 135message. Any line that is of form: 136 137* three-dashes and end-of-line, or 138* a line that begins with "diff -", or 139* a line that begins with "Index: " 140 141is taken as the beginning of a patch, and the commit log message 142is terminated before the first occurrence of such a line. 143 144When initially invoking it, you give it names of the mailboxes 145to crunch. Upon seeing the first patch that does not apply, it 146aborts in the middle,. You can recover from this in one of two ways: 147 148. skip the current patch by re-running the command with '--skip' 149 option. 150 151. hand resolve the conflict in the working directory, and update 152 the index file to bring it in a state that the patch should 153 have produced. Then run the command with '--resolved' option. 154 155The command refuses to process new mailboxes while `.git/rebase-apply` 156directory exists, so if you decide to start over from scratch, 157run `rm -f -r .git/rebase-apply` before running the command with mailbox 158names. 159 160Before any patches are applied, ORIG_HEAD is set to the tip of the 161current branch. This is useful if you have problems with multiple 162commits, like running 'git am' on the wrong branch or an error in the 163commits that is more easily fixed by changing the mailbox (e.g. 164errors in the "From:" lines). 165 166 167SEE ALSO 168-------- 169linkgit:git-apply[1]. 170 171 172Author 173------ 174Written by Junio C Hamano <gitster@pobox.com> 175 176Documentation 177-------------- 178Documentation by Petr Baudis, Junio C Hamano and the git-list <git@vger.kernel.org>. 179 180GIT 181--- 182Part of the linkgit:git[1] suite
