6 git-am - Apply a series of patches from a mailbox
9 SYNOPSIS
10 --------
11 [verse]
12 'git-am' [--signoff] [--dotest=<dir>] [--utf8 | --no-utf8] [--binary] [--3way]
13 [--interactive] [--whitespace=<option>] [-C<n>] [-p<n>]
14 <mbox>...
15 'git-am' [--skip | --resolved]
17 DESCRIPTION
18 -----------
19 Splits mail messages in a mailbox into commit log message,
20 authorship information and patches, and applies them to the
21 current branch.
23 OPTIONS
24 -------
25 <mbox>...::
26 The list of mailbox files to read patches from. If you do not
27 supply this argument, reads from the standard input.
29 -s, --signoff::
30 Add `Signed-off-by:` line to the commit message, using
31 the committer identity of yourself.
33 -d=<dir>, --dotest=<dir>::
34 Instead of `.dotest` directory, use <dir> as a working
35 area to store extracted patches.
37 -k, --keep::
38 Pass `-k` flag to `git-mailinfo` (see gitlink:git-mailinfo[1]).
40 -u, --utf8::
41 Pass `-u` flag to `git-mailinfo` (see gitlink:git-mailinfo[1]).
42 The proposed commit log message taken from the e-mail
43 are re-coded into UTF-8 encoding (configuration variable
44 `i18n.commitencoding` can be used to specify project's
45 preferred encoding if it is not UTF-8).
46 +
47 This was optional in prior versions of git, but now it is the
48 default. You could use `--no-utf8` to override this.
50 --no-utf8::
51 Pass `-n` flag to `git-mailinfo` (see
52 gitlink:git-mailinfo[1]).
54 -b, --binary::
55 Pass `--allow-binary-replacement` flag to `git-apply`
56 (see gitlink:git-apply[1]).
58 -3, --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 locally.
64 --skip::
65 Skip the current patch. This is only meaningful when
66 restarting an aborted patch.
68 --whitespace=<option>::
69 This flag is passed to the `git-apply` program that applies
70 the patch.
72 -C<n>, -p<n>::
73 These flags are passed to the `git-apply` program that applies
74 the patch.
76 -i, --interactive::
77 Run interactively, just like git-applymbox.
79 -r, --resolved::
80 After a patch failure (e.g. attempting to apply
81 conflicting patch), the user has applied it by hand and
82 the index file stores the result of the application.
83 Make a commit using the authorship and commit log
84 extracted from the e-mail message and the current index
85 file, and continue.
87 --resolvemsg=<msg>::
88 When a patch failure occurs, <msg> will be printed
89 to the screen before exiting. This overrides the
90 standard message informing you to use `--resolved`
91 or `--skip` to handle the failure. This is solely
92 for internal use between `git-rebase` and `git-am`.
94 DISCUSSION
95 ----------
97 The commit author name is taken from the "From: " line of the
98 message, and commit author time is taken from the "Date: " line
99 of the message. The "Subject: " line is used as the title of
100 the commit, after stripping common prefix "[PATCH <anything>]".
101 It is supposed to describe what the commit is about concisely as
102 a one line text.
104 The body of the message (iow, after a blank line that terminates
105 RFC2822 headers) can begin with "Subject: " and "From: " lines
106 that are different from those of the mail header, to override
107 the values of these fields.
109 The commit message is formed by the title taken from the
110 "Subject: ", a blank line and the body of the message up to
111 where the patch begins. Excess whitespaces at the end of the
112 lines are automatically stripped.
114 The patch is expected to be inline, directly following the
115 message. Any line that is of form:
117 * three-dashes and end-of-line, or
118 * a line that begins with "diff -", or
119 * a line that begins with "Index: "
121 is taken as the beginning of a patch, and the commit log message
122 is terminated before the first occurrence of such a line.
124 When initially invoking it, you give it names of the mailboxes
125 to crunch. Upon seeing the first patch that does not apply, it
126 aborts in the middle, just like 'git-applymbox' does. You can
127 recover from this in one of two ways:
129 . skip the current one by re-running the command with '--skip'
130 option.
132 . hand resolve the conflict in the working directory, and update
133 the index file to bring it in a state that the patch should
134 have produced. Then run the command with '--resolved' option.
136 The command refuses to process new mailboxes while `.dotest`
137 directory exists, so if you decide to start over from scratch,
138 run `rm -f .dotest` before running the command with mailbox
139 names.
