If you do not + supply this argument, the command reads from the standard input. + If you supply directories, they will be treated as Maildirs. + +-s:: +--signoff:: + Add a `Signed-off-by:` line to the commit message, using + the committer identity of yourself. + +-k:: +--keep:: + Pass `-k` flag to 'git mailinfo' (see linkgit:git-mailinfo[1]). + +--keep-non-patch:: + Pass `-b` flag to 'git mailinfo' (see linkgit:git-mailinfo[1]). + +--keep-cr:: +--no-keep-cr:: + With `--keep-cr`, call 'git mailsplit' (see linkgit:git-mailsplit[1]) + with the same option, to prevent it from stripping CR at the end of + lines. `am.keepcr` configuration variable can be used to specify the + default behaviour. `--no-keep-cr` is useful to override `am.keepcr`. + +-c:: +--scissors:: + Remove everything in body before a scissors line (see + linkgit:git-mailinfo[1]). + +--no-scissors:: + Ignore scissors lines (see linkgit:git-mailinfo[1]). + +-q:: +--quiet:: + Be quiet. Only print error messages. + +-u:: +--utf8:: + Pass `-u` flag to 'git mailinfo' (see linkgit:git-mailinfo[1]). + The proposed commit log message taken from the e-mail + is re-coded into UTF-8 encoding (configuration variable + `i18n.commitencoding` can be used to specify project's + preferred encoding if it is not UTF-8). ++ +This was optional in prior versions of git, but now it is the +default. You can use `--no-utf8` to override this. + +--no-utf8:: + Pass `-n` flag to 'git mailinfo' (see + linkgit:git-mailinfo[1]). + +-3:: +--3way:: + When the patch does not apply cleanly, fall back on + 3-way merge if the patch records the identity of blobs + it is supposed to apply to and we have those blobs + available locally. + +--ignore-date:: +--ignore-space-change:: +--ignore-whitespace:: +--whitespace=<option>:: +-C<n>:: +-p<n>:: +--directory=<dir>:: +--exclude=<path>:: +--include=<path>:: +--reject:: + These flags are passed to the 'git apply' (see linkgit:git-apply[1]) + program that applies + the patch. + +-i:: +--interactive:: + Run interactively. + +--committer-date-is-author-date:: + By default the command records the date from the e-mail + message as the commit author date, and uses the time of + commit creation as the committer date. This allows the + user to lie about the committer date by using the same + value as the author date. + +--ignore-date:: + By default the command records the date from the e-mail + message as the commit author date, and uses the time of + commit creation as the committer date. This allows the + user to lie about the author date by using the same + value as the committer date. + +--skip:: + Skip the current patch. This is only meaningful when + restarting an aborted patch. + +--continue:: +-r:: +--resolved:: + After a patch failure (e.g. attempting to apply + conflicting patch), the user has applied it by hand and + the index file stores the result of the application. + Make a commit using the authorship and commit log + extracted from the e-mail message and the current index + file, and continue. + +--resolvemsg=<msg>:: + When a patch failure occurs, <msg> will be printed + to the screen before exiting. This overrides the + standard message informing you to use `--resolved` + or `--skip` to handle the failure. This is solely + for internal use between 'git rebase' and 'git am'. + +--abort:: + Restore the original branch and abort the patching operation. + +DISCUSSION +---------- + +The commit author name is taken from the "From: " line of the +message, and commit author date is taken from the "Date: " line +of the message. The "Subject: " line is used as the title of +the commit, after stripping common prefix "[PATCH <anything>]". +The "Subject: " line is supposed to concisely describe what the +commit is about in one line of text. + +"From: " and "Subject: " lines starting the body override the respective +commit author name and title values taken from the headers. + +The commit message is formed by the title taken from the +"Subject: ", a blank line and the body of the message up to +where the patch begins. Excess whitespace at the end of each +line is automatically stripped. + +The patch is expected to be inline, directly following the +message. Any line that is of the form: + +* three-dashes and end-of-line, or +* a line that begins with "diff -", or +* a line that begins with "Index: " + +is taken as the beginning of a patch, and the commit log message +is terminated before the first occurrence of such a line. + +When initially invoking `git am`, you give it the names of the mailboxes +to process. Upon seeing the first patch that does not apply, it +aborts in the middle. You can recover from this in one of two ways: + +. skip the current patch by re-running the command with the '--skip' + option. + +. hand resolve the conflict in the working directory, and update + the index file to bring it into a state that the patch should + have produced. Then run the command with the '--resolved' option. + +The command refuses to process new mailboxes until the current +operation is finished, so if you decide to start over from scratch, +run `git am --abort` before running the command with mailbox +names. + +Before any patches are applied, ORIG_HEAD is set to the tip of the +current branch. This is useful if you have problems with multiple +commits, like running 'git am' on the wrong branch or an error in the +commits that is more easily fixed by changing the mailbox (e.g. +errors in the "From:" lines). + + +SEE ALSO +-------- +linkgit:git-apply[1]. + +GIT +--- +Part of the linkgit:git[1] suite |
