JH
15Shows the commit logs.
16
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
JH
20each commit introduces are shown.

JH
30 Show only commits between the named two commits. When
31 either <since> or <until> is omitted, it defaults to
32 `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 57 commits, and doesn't limit diff for those commits.

59Note that this affects all diff-based output types, e.g. those
60produced by --stat etc.

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.

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

141Configuration
142-------------
143
144See linkgit:git-config[1] for core variables and linkgit:git-diff[1]
145for settings related to diff generation.
146
147format.pretty::
148 Default for the `--format` option. (See "PRETTY FORMATS" above.)
149 Defaults to "medium".
150
151i18n.logOutputEncoding::
152 Encoding to use when displaying logs. (See "Discussion", above.)
153 Defaults to the value of `i18n.commitEncoding` if set, UTF-8
154 otherwise.
155
156log.date::
157 Default format for human-readable dates. (Compare the
158 `--date` option.) Defaults to "default", which means to write
159 dates like `Sat May 8 19:35:34 2010 -0500`.
160
161log.showroot::
162 If `false`, 'git log' and related commands will not treat the
163 initial commit as a big creation event. Any root commits in
164 `git log -p` output would be shown without a diff attached.
165 The default is `true`.
166
167mailmap.file::
168 See linkgit:git-shortlog[1].
169
170notes.displayRef::
171 Which refs, in addition to the default set by `core.notesRef`
172 or 'GIT_NOTES_REF', to read notes from when showing commit
173 messages with the 'log' family of commands. See
174 linkgit:git-notes[1].
175+
176May be an unabbreviated ref name or a glob and may be specified
177multiple times. A warning will be issued for refs that do not exist,
178but a glob that does not match any refs is silently ignored.
179+
180This setting can be disabled by the `--no-standard-notes` option,
181overridden by the 'GIT_NOTES_DISPLAY_REF' environment variable,
182and supplemented by the `--show-notes` option.
