NAME

6       git-commit-tree - Create a new commit object
7

SYNOPSIS

9       git commit-tree <tree> [(-p <parent>)...]
10       git commit-tree [(-p <parent>)...] [-S[<keyid>]] [(-m <message>)...]
11                         [(-F <file>)...] <tree>
12

DESCRIPTION

14       This is usually not what an end user wants to run directly. See git-
15       commit(1) instead.
16
17       Creates a new commit object based on the provided tree object and emits
18       the new commit object id on stdout. The log message is read from the
19       standard input, unless -m or -F options are given.
20
21       The -m and -F options can be given any number of times, in any order.
22       The commit log message will be composed in the order in which the
23       options are given.
24
25       A commit object may have any number of parents. With exactly one
26       parent, it is an ordinary commit. Having more than one parent makes the
27       commit a merge between several lines of history. Initial (root) commits
28       have no parents.
29
30       While a tree represents a particular directory state of a working
31       directory, a commit represents that state in "time", and explains how
32       to get there.
33
34       Normally a commit would identify a new "HEAD" state, and while Git
35       doesn’t care where you save the note about that state, in practice we
36       tend to just write the result to the file that is pointed at by
37       .git/HEAD, so that we can always see what the last committed state was.
38

OPTIONS

40       <tree>
41           An existing tree object.
42
43       -p <parent>
44           Each -p indicates the id of a parent commit object.
45
46       -m <message>
47           A paragraph in the commit log message. This can be given more than
48           once and each <message> becomes its own paragraph.
49
50       -F <file>
51           Read the commit log message from the given file. Use - to read from
52           the standard input. This can be given more than once and the
53           content of each file becomes its own paragraph.
54
55       -S[<keyid>], --gpg-sign[=<keyid>], --no-gpg-sign
56           GPG-sign commits. The keyid argument is optional and defaults to
57           the committer identity; if specified, it must be stuck to the
58           option without a space.  --no-gpg-sign is useful to countermand a
59           --gpg-sign option given earlier on the command line.
60

COMMIT INFORMATION

62       A commit encapsulates:
63
64       •   all parent object ids
65
66       •   author name, email and date
67
68       •   committer name and email and the commit time.
69
70       A commit comment is read from stdin. If a changelog entry is not
71       provided via "<" redirection, git commit-tree will just wait for one to
72       be entered and terminated with ^D.
73

DATE FORMATS

75       The GIT_AUTHOR_DATE and GIT_COMMITTER_DATE environment variables
76       support the following date formats:
77
78       Git internal format
79           It is <unix timestamp> <time zone offset>, where <unix timestamp>
80           is the number of seconds since the UNIX epoch.  <time zone offset>
81           is a positive or negative offset from UTC. For example CET (which
82           is 1 hour ahead of UTC) is +0100.
83
84       RFC 2822
85           The standard email format as described by RFC 2822, for example
86           Thu, 07 Apr 2005 22:13:13 +0200.
87
88       ISO 8601
89           Time and date specified by the ISO 8601 standard, for example
90           2005-04-07T22:13:13. The parser accepts a space instead of the T
91           character as well. Fractional parts of a second will be ignored,
92           for example 2005-04-07T22:13:13.019 will be treated as
93           2005-04-07T22:13:13.
94
95               Note
96               In addition, the date part is accepted in the following
97               formats: YYYY.MM.DD, MM/DD/YYYY and DD.MM.YYYY.

DISCUSSION

100       Git is to some extent character encoding agnostic.
101
102       •   The contents of the blob objects are uninterpreted sequences of
103           bytes. There is no encoding translation at the core level.
104
105       •   Path names are encoded in UTF-8 normalization form C. This applies
106           to tree objects, the index file, ref names, as well as path names
107           in command line arguments, environment variables and config files
108           (.git/config (see git-config(1)), gitignore(5), gitattributes(5)
109           and gitmodules(5)).
110
111           Note that Git at the core level treats path names simply as
112           sequences of non-NUL bytes, there are no path name encoding
113           conversions (except on Mac and Windows). Therefore, using non-ASCII
114           path names will mostly work even on platforms and file systems that
115           use legacy extended ASCII encodings. However, repositories created
116           on such systems will not work properly on UTF-8-based systems (e.g.
117           Linux, Mac, Windows) and vice versa. Additionally, many Git-based
118           tools simply assume path names to be UTF-8 and will fail to display
119           other encodings correctly.
120
121       •   Commit log messages are typically encoded in UTF-8, but other
122           extended ASCII encodings are also supported. This includes
123           ISO-8859-x, CP125x and many others, but not UTF-16/32, EBCDIC and
124           CJK multi-byte encodings (GBK, Shift-JIS, Big5, EUC-x, CP9xx etc.).
125
126       Although we encourage that the commit log messages are encoded in
127       UTF-8, both the core and Git Porcelain are designed not to force UTF-8
128       on projects. If all participants of a particular project find it more
129       convenient to use legacy encodings, Git does not forbid it. However,
130       there are a few things to keep in mind.
131
132        1. git commit and git commit-tree issues a warning if the commit log
133           message given to it does not look like a valid UTF-8 string, unless
134           you explicitly say your project uses a legacy encoding. The way to
135           say this is to have i18n.commitEncoding in .git/config file, like
136           this:
137
138               [i18n]
139                       commitEncoding = ISO-8859-1
140
141           Commit objects created with the above setting record the value of
142           i18n.commitEncoding in its encoding header. This is to help other
143           people who look at them later. Lack of this header implies that the
144           commit log message is encoded in UTF-8.
145
146        2. git log, git show, git blame and friends look at the encoding
147           header of a commit object, and try to re-code the log message into
148           UTF-8 unless otherwise specified. You can specify the desired
149           output encoding with i18n.logOutputEncoding in .git/config file,
150           like this:
151
152               [i18n]
153                       logOutputEncoding = ISO-8859-1
154
155           If you do not have this configuration variable, the value of
156           i18n.commitEncoding is used instead.
157
158       Note that we deliberately chose not to re-code the commit log message
159       when a commit is made to force UTF-8 at the commit object level,
160       because re-coding to UTF-8 is not necessarily a reversible operation.
