0b444cdb 18The command takes options applicable to the 'git rev-list'
e51c3b50 19command to control what is shown and how, and options applicable to
0b444cdb 20the 'git diff-*' commands to control how the changes
e51c3b50

JH
28 Show only commits between the named two commits. When
29 either <since> or <until> is omitted, it defaults to
30 `HEAD`, i.e. the tip of the current branch.
41a5564e 31 For a more complete list of ways to spell <since>
9d83e382 32 and <until>, see linkgit:gitrevisions[7].

34--follow::
35 Continue listing the history of a file beyond renames
36 (works only for a single file).

38--no-decorate::
39--decorate[=short|full|no]::
33e7018c
LH
40 Print out the ref names of any commits that are shown. If 'short' is
41 specified, the ref name prefixes 'refs/heads/', 'refs/tags/' and
42 'refs/remotes/' will not be printed. If 'full' is specified, the
43 full ref name (including prefix) will be printed. The default option
44 is 'short'.
56822cc9 45
30c4d7a7
NS
46--source::
47 Print out the ref name given on the command line by which each
48 commit was reached.

50--use-mailmap::
51 Use mailmap file to map author and committer names and email
52 to canonical real names and email addresses. See
53 linkgit:git-shortlog[1].
54
2e88c266 55--full-diff::
f448e24e 56 Without this flag, "git log -p <path>..." shows commits that
2e88c266
JN
57 touch the specified paths, and diffs about the same specified
58 paths. With this, the full diff is shown for commits that touch
f448e24e 59 the specified paths; this means that "<path>..." limits only
2e88c266 60 commits, and doesn't limit diff for those commits.

62Note that this affects all diff-based output types, e.g. those
63produced by --stat etc.
2e88c266 64

MC
65--log-size::
66 Before the log message print out its size in bytes. Intended
2de9b711 67 mainly for porcelain tools consumption. If Git is unable to
9fa3465d
MC
68 produce a valid value size is set to zero.
69 Note that only message is considered, if also a diff is shown
70 its size is not included.
71
b1524ee0 72[\--] <path>...::
b15b5b10
TR
73 Show only commits that are enough to explain how the files
74 that match the specified paths came to be. See "History
75 Simplification" below for details and other simplification
76 modes.
77+
78To prevent confusion with options and branch names, paths may need to
79be prefixed with "\-- " to separate them from options or refnames.

93Examples
94--------
5d2fc913 95`git log --no-merges`::
bd663611
LT
96
97 Show the whole commit history, but skip any merges
98
5d2fc913 99`git log v2.6.12.. include/scsi drivers/scsi`::
bd663611
LT
100
101 Show all commits since version 'v2.6.12' that changed any file
102 in the include/scsi or drivers/scsi subdirectories
103
6cf378f0 104`git log --since="2 weeks ago" -- gitk`::
bd663611
LT
105
106 Show the changes during the last two weeks to the file 'gitk'.
107 The "--" is necessary to avoid confusion with the *branch* named
108 'gitk'
109
5d2fc913 110`git log --name-status release..test`::
e51c3b50
JH
111
112 Show the commits that are in the "test" branch but not yet
113 in the "release" branch, along with the list of paths
114 each commit modifies.
bd663611 115
5d2fc913 116`git log --follow builtin-rev-list.c`::
4f50f6a9
SW
117
118 Shows the commits that changed builtin-rev-list.c, including
119 those commits that occurred before the file was given its
120 present name.
121
5d2fc913 122`git log --branches --not --remotes=origin`::
d08bae7e
IL
123
124 Shows all commits that are in any of local branches but not in
0e615b25 125 any of remote-tracking branches for 'origin' (what you have that
d08bae7e
IL
126 origin doesn't).
127
5d2fc913 128`git log master --not --remotes=*/master`::
d08bae7e
IL
129
130 Shows all commits that are in local master but not in any remote
131 repository master branches.
132
5d2fc913 133`git log -p -m --first-parent`::
88d9d45d
PB
134
135 Shows the history including change diffs, but only from the
136 "main branch" perspective, skipping commits that come from merged
137 branches, and showing full diffs of changes introduced by the merges.
138 This makes sense only when following a strict policy of merging all
139 topic branches when staying on a single integration branch.
140
70c2a258
NTND
141`git log -3`::
142 Limits the number of commits to show to 3.

149Configuration
150-------------
151
152See linkgit:git-config[1] for core variables and linkgit:git-diff[1]
153for settings related to diff generation.
154
155format.pretty::
156 Default for the `--format` option. (See "PRETTY FORMATS" above.)
157 Defaults to "medium".
158
159i18n.logOutputEncoding::
160 Encoding to use when displaying logs. (See "Discussion", above.)
161 Defaults to the value of `i18n.commitEncoding` if set, UTF-8
162 otherwise.
163
164log.date::
165 Default format for human-readable dates. (Compare the
166 `--date` option.) Defaults to "default", which means to write
167 dates like `Sat May 8 19:35:34 2010 -0500`.
168
169log.showroot::
170 If `false`, 'git log' and related commands will not treat the
171 initial commit as a big creation event. Any root commits in
172 `git log -p` output would be shown without a diff attached.
173 The default is `true`.
174
d5422b0c 175mailmap.*::
59893a88
JN
176 See linkgit:git-shortlog[1].
177
178notes.displayRef::
179 Which refs, in addition to the default set by `core.notesRef`
180 or 'GIT_NOTES_REF', to read notes from when showing commit
181 messages with the 'log' family of commands. See
182 linkgit:git-notes[1].
183+
184May be an unabbreviated ref name or a glob and may be specified
185multiple times. A warning will be issued for refs that do not exist,
186but a glob that does not match any refs is silently ignored.
187+
ab18b2c0 188This setting can be disabled by the `--no-notes` option,
59893a88 189overridden by the 'GIT_NOTES_DISPLAY_REF' environment variable,
ab18b2c0 190and overridden by the `--notes=<ref>` option.
