   9 SYNOPSIS
  10 --------
  11 [verse]
  12 'git log' [<options>] [<since>..<until>] [[\--] <path>...]
  13
  14 DESCRIPTION
  15 -----------
  16 Shows the commit logs.
  17
  18 The command takes options applicable to the 'git rev-list'
  19 command to control what is shown and how, and options applicable to
  20 the 'git diff-*' commands to control how the changes
  21 each commit introduces are shown.
  22
  23
  24 OPTIONS
  25 -------
  26
  27 <since>..<until>::
  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.
  31         For a more complete list of ways to spell <since>
  32         and <until>, see linkgit:gitrevisions[7].
  33
  34 --follow::
  35         Continue listing the history of a file beyond renames
  36         (works only for a single file).
  37
  38 --no-decorate::
  39 --decorate[=short|full|no]::
  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'.
  45
  46 --source::
  47         Print out the ref name given on the command line by which each
  48         commit was reached.
  49
  50 --full-diff::
  51         Without this flag, "git log -p <path>..." shows commits that
  52         touch the specified paths, and diffs about the same specified
  53         paths.  With this, the full diff is shown for commits that touch
  54         the specified paths; this means that "<path>..." limits only
  55         commits, and doesn't limit diff for those commits.
  56 +
  57 Note that this affects all diff-based output types, e.g. those
  58 produced by --stat etc.
  59
  60 --log-size::
  61         Before the log message print out its size in bytes. Intended
  62         mainly for porcelain tools consumption. If git is unable to
  63         produce a valid value size is set to zero.
  64         Note that only message is considered, if also a diff is shown
  65         its size is not included.
  66
  67 [\--] <path>...::
  68         Show only commits that are enough to explain how the files
  69         that match the specified paths came to be.  See "History
  70         Simplification" below for details and other simplification
  71         modes.
  72 +
  73 To prevent confusion with options and branch names, paths may need to
  74 be prefixed with "\-- " to separate them from options or refnames.

  88 Examples
  89 --------
  90 `git log --no-merges`::
  91
  92         Show the whole commit history, but skip any merges
  93
  94 `git log v2.6.12.. include/scsi drivers/scsi`::
  95
  96         Show all commits since version 'v2.6.12' that changed any file
  97         in the include/scsi or drivers/scsi subdirectories
  98
  99 `git log --since="2 weeks ago" -- gitk`::
 100
 101         Show the changes during the last two weeks to the file 'gitk'.
 102         The "--" is necessary to avoid confusion with the *branch* named
 103         'gitk'
 104
 105 `git log --name-status release..test`::
 106
 107         Show the commits that are in the "test" branch but not yet
 108         in the "release" branch, along with the list of paths
 109         each commit modifies.
 110
 111 `git log --follow builtin-rev-list.c`::
 112
 113         Shows the commits that changed builtin-rev-list.c, including
 114         those commits that occurred before the file was given its
 115         present name.
 116
 117 `git log --branches --not --remotes=origin`::
 118
 119         Shows all commits that are in any of local branches but not in
 120         any of remote-tracking branches for 'origin' (what you have that
 121         origin doesn't).
 122
 123 `git log master --not --remotes=*/master`::
 124
 125         Shows all commits that are in local master but not in any remote
 126         repository master branches.
 127
 128 `git log -p -m --first-parent`::
 129
 130         Shows the history including change diffs, but only from the
 131         "main branch" perspective, skipping commits that come from merged
 132         branches, and showing full diffs of changes introduced by the merges.
 133         This makes sense only when following a strict policy of merging all
 134         topic branches when staying on a single integration branch.
 135
 136 `git log -3`::
 137         Limits the number of commits to show to 3.

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