9 SYNOPSIS
10 --------
11 'git-log' <option>...
12
13 DESCRIPTION
14 -----------
15 Shows the commit logs.
16
17 The command takes options applicable to the gitlink:git-rev-list[1]
18 command to control what is shown and how, and options applicable to
19 the gitlink:git-diff-tree[1] commands to control how the changes
20 each commit introduces are shown.
21
22 This manual page describes only the most frequently used options.

25 OPTIONS
26 -------
27
28 include::pretty-options.txt[]
29
30 -<n>::
31 Limits the number of commits to show.
32
33 <since>..<until>::
34 Show only commits between the named two commits. When
35 either <since> or <until> is omitted, it defaults to
36 `HEAD`, i.e. the tip of the current branch.
37 For a more complete list of ways to spell <since>
38 and <until>, see "SPECIFYING REVISIONS" section in
39 gitlink:git-rev-parse[1].
40
41 --first-parent::
42 Follow only the first parent commit upon seeing a merge
43 commit. This option gives a better overview of the
44 evolution of a particular branch.
45
46 -p::
47 Show the change the commit introduces in a patch form.
48
49 -g, \--walk-reflogs::
50 Show commits as they were recorded in the reflog. The log contains
51 a record about how the tip of a reference was changed.
52 See also gitlink:git-reflog[1].
53
54 --decorate::
55 Print out the ref names of any commits that are shown.
56
57 --full-diff::
58 Without this flag, "git log -p <paths>..." shows commits that
59 touch the specified paths, and diffs about the same specified
60 paths. With this, the full diff is shown for commits that touch
61 the specified paths; this means that "<paths>..." limits only
62 commits, and doesn't limit diff for those commits.
63
64 --follow::
65 Continue listing the history of a file beyond renames.
66
67 --log-size::
68 Before the log message print out its size in bytes. Intended
69 mainly for porcelain tools consumption. If git is unable to
70 produce a valid value size is set to zero.
71 Note that only message is considered, if also a diff is shown
72 its size is not included.
73
74 <paths>...::
75 Show only commits that affect the specified paths.

81 Examples
82 --------
83 git log --no-merges::
84
85 Show the whole commit history, but skip any merges
86
87 git log v2.6.12.. include/scsi drivers/scsi::
88
89 Show all commits since version 'v2.6.12' that changed any file
90 in the include/scsi or drivers/scsi subdirectories
91
92 git log --since="2 weeks ago" \-- gitk::
93
94 Show the changes during the last two weeks to the file 'gitk'.
95 The "--" is necessary to avoid confusion with the *branch* named
96 'gitk'
97
98 git log -r --name-status release..test::
99
100 Show the commits that are in the "test" branch but not yet
101 in the "release" branch, along with the list of paths
102 each commit modifies.
103
104 git log --follow builtin-rev-list.c::
105
106 Shows the commits that changed builtin-rev-list.c, including
107 those commits that occurred before the file was given its
108 present name.
