   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 --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
  55 --full-diff::
  56         Without this flag, "git log -p <path>..." shows commits that
  57         touch the specified paths, and diffs about the same specified
  58         paths.  With this, the full diff is shown for commits that touch
  59         the specified paths; this means that "<path>..." limits only
  60         commits, and doesn't limit diff for those commits.
  61 +
  62 Note that this affects all diff-based output types, e.g. those
  63 produced by --stat etc.
  64
  65 --log-size::
  66         Before the log message print out its size in bytes. Intended
  67         mainly for porcelain tools consumption. If Git is unable to
  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
  72 [\--] <path>...::
  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 +
  78 To prevent confusion with options and branch names, paths may need to
  79 be prefixed with "\-- " to separate them from options or refnames.

  93 Examples
  94 --------
  95 `git log --no-merges`::
  96
  97         Show the whole commit history, but skip any merges
  98
  99 `git log v2.6.12.. include/scsi drivers/scsi`::
 100
 101         Show all commits since version 'v2.6.12' that changed any file
 102         in the include/scsi or drivers/scsi subdirectories
 103
 104 `git log --since="2 weeks ago" -- gitk`::
 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
 110 `git log --name-status release..test`::
 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.
 115
 116 `git log --follow builtin-rev-list.c`::
 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
 122 `git log --branches --not --remotes=origin`::
 123
 124         Shows all commits that are in any of local branches but not in
 125         any of remote-tracking branches for 'origin' (what you have that
 126         origin doesn't).
 127
 128 `git log master --not --remotes=*/master`::
 129
 130         Shows all commits that are in local master but not in any remote
 131         repository master branches.
 132
 133 `git log -p -m --first-parent`::
 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
 141 `git log -3`::
 142         Limits the number of commits to show to 3.

 149 Configuration
 150 -------------
 151
 152 See linkgit:git-config[1] for core variables and linkgit:git-diff[1]
 153 for settings related to diff generation.
 154
 155 format.pretty::
 156         Default for the `--format` option.  (See "PRETTY FORMATS" above.)
 157         Defaults to "medium".
 158
 159 i18n.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
 164 log.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
 169 log.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
 175 mailmap.*::
 176         See linkgit:git-shortlog[1].
 177
 178 notes.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 +
 184 May be an unabbreviated ref name or a glob and may be specified
 185 multiple times.  A warning will be issued for refs that do not exist,
 186 but a glob that does not match any refs is silently ignored.
 187 +
 188 This setting can be disabled by the `--no-notes` option,
 189 overridden by the 'GIT_NOTES_DISPLAY_REF' environment variable,
 190 and overridden by the `--notes=<ref>` option.
