JH
15Shows the commit logs.

0b444cdb 17The command takes options applicable to the 'git rev-list'
e51c3b50 18command to control what is shown and how, and options applicable to
0b444cdb 19the 'git diff-*' commands to control how the changes
e51c3b50

30 Limits the number of commits to show.
31
32<since>..<until>::

JH
33 Show only commits between the named two commits. When
34 either <since> or <until> is omitted, it defaults to
35 `HEAD`, i.e. the tip of the current branch.

40--no-decorate::
41--decorate[=short|full|no]::
33e7018c
LH
42 Print out the ref names of any commits that are shown. If 'short' is
43 specified, the ref name prefixes 'refs/heads/', 'refs/tags/' and
44 'refs/remotes/' will not be printed. If 'full' is specified, the
45 full ref name (including prefix) will be printed. The default option
46 is 'short'.

NS
48--source::
49 Print out the ref name given on the command line by which each
50 commit was reached.
51
2e88c266 52--full-diff::
f448e24e 53 Without this flag, "git log -p <path>..." shows commits that
2e88c266
JN
54 touch the specified paths, and diffs about the same specified
55 paths. With this, the full diff is shown for commits that touch
f448e24e 56 the specified paths; this means that "<path>..." limits only
2e88c266
JN
57 commits, and doesn't limit diff for those commits.
58
4f50f6a9 59--follow::
0cdca133 60 Continue listing the history of a file beyond renames/copies.

62--log-size::
63 Before the log message print out its size in bytes. Intended
64 mainly for porcelain tools consumption. If git is unable to
65 produce a valid value size is set to zero.
66 Note that only message is considered, if also a diff is shown
67 its size is not included.
68
b1524ee0 69[\--] <path>...::
70 Show only commits that affect any of the specified paths. To
71 prevent confusion with options and branch names, paths may need
72 to be prefixed with "\-- " to separate them from options or
73 refnames.

82Examples
83--------
84git log --no-merges::
85
86 Show the whole commit history, but skip any merges
87
88git log v2.6.12.. include/scsi drivers/scsi::
89
90 Show all commits since version 'v2.6.12' that changed any file
91 in the include/scsi or drivers/scsi subdirectories
92
e994004f 93git log --since="2 weeks ago" \-- gitk::
bd663611
LT
94
95 Show the changes during the last two weeks to the file 'gitk'.
96 The "--" is necessary to avoid confusion with the *branch* named
97 'gitk'
98
170c0438 99git log --name-status release..test::
e51c3b50
JH
100
101 Show the commits that are in the "test" branch but not yet
102 in the "release" branch, along with the list of paths
103 each commit modifies.
bd663611 104
4f50f6a9
SW
105git log --follow builtin-rev-list.c::
106
107 Shows the commits that changed builtin-rev-list.c, including
108 those commits that occurred before the file was given its
109 present name.
110
b09fe971 111git log --branches --not --remotes=origin::
d08bae7e
IL
112
113 Shows all commits that are in any of local branches but not in
114 any of remote tracking branches for 'origin' (what you have that
115 origin doesn't).
116
b09fe971 117git log master --not --remotes=*/master::
d08bae7e
IL
118
119 Shows all commits that are in local master but not in any remote
120 repository master branches.
121
88d9d45d
PB
122git log -p -m --first-parent::
123
124 Shows the history including change diffs, but only from the
125 "main branch" perspective, skipping commits that come from merged
126 branches, and showing full diffs of changes introduced by the merges.
127 This makes sense only when following a strict policy of merging all
128 topic branches when staying on a single integration branch.

136Configuration
137-------------
138
139See linkgit:git-config[1] for core variables and linkgit:git-diff[1]
140for settings related to diff generation.
141
142format.pretty::
143 Default for the `--format` option. (See "PRETTY FORMATS" above.)
144 Defaults to "medium".
145
146i18n.logOutputEncoding::
147 Encoding to use when displaying logs. (See "Discussion", above.)
148 Defaults to the value of `i18n.commitEncoding` if set, UTF-8
149 otherwise.
150
151log.date::
152 Default format for human-readable dates. (Compare the
153 `--date` option.) Defaults to "default", which means to write
154 dates like `Sat May 8 19:35:34 2010 -0500`.
155
156log.showroot::
157 If `false`, 'git log' and related commands will not treat the
158 initial commit as a big creation event. Any root commits in
159 `git log -p` output would be shown without a diff attached.
160 The default is `true`.
161
162mailmap.file::
163 See linkgit:git-shortlog[1].
164
165notes.displayRef::
166 Which refs, in addition to the default set by `core.notesRef`
167 or 'GIT_NOTES_REF', to read notes from when showing commit
168 messages with the 'log' family of commands. See
169 linkgit:git-notes[1].
170+
171May be an unabbreviated ref name or a glob and may be specified
172multiple times. A warning will be issued for refs that do not exist,
173but a glob that does not match any refs is silently ignored.
174+
175This setting can be disabled by the `--no-standard-notes` option,
176overridden by the 'GIT_NOTES_DISPLAY_REF' environment variable,
177and supplemented by the `--show-notes` option.
