   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 -<n>::
  28         Limits the number of commits to show.
  29         Note that this is a commit limiting option, see below.
  30
  31 <since>..<until>::
  32         Show only commits between the named two commits.  When
  33         either <since> or <until> is omitted, it defaults to
  34         `HEAD`, i.e. the tip of the current branch.
  35         For a more complete list of ways to spell <since>
  36         and <until>, see linkgit:gitrevisions[7].
  37
  38 --follow::
  39         Continue listing the history of a file beyond renames
  40         (works only for a single file).
  41
  42 --no-decorate::
  43 --decorate[=short|full|no]::
  44         Print out the ref names of any commits that are shown. If 'short' is
  45         specified, the ref name prefixes 'refs/heads/', 'refs/tags/' and
  46         'refs/remotes/' will not be printed. If 'full' is specified, the
  47         full ref name (including prefix) will be printed. The default option
  48         is 'short'.
  49
  50 --source::
  51         Print out the ref name given on the command line by which each
  52         commit was reached.
  53
  54 --full-diff::
  55         Without this flag, "git log -p <path>..." shows commits that
  56         touch the specified paths, and diffs about the same specified
  57         paths.  With this, the full diff is shown for commits that touch
  58         the specified paths; this means that "<path>..." limits only
  59         commits, and doesn't limit diff for those commits.
  60 +
  61 Note that this affects all diff-based output types, e.g. those
  62 produced by --stat etc.
  63
  64 --log-size::
  65         Before the log message print out its size in bytes. Intended
  66         mainly for porcelain tools consumption. If git is unable to
  67         produce a valid value size is set to zero.
  68         Note that only message is considered, if also a diff is shown
  69         its size is not included.
  70
  71 [\--] <path>...::
  72         Show only commits that are enough to explain how the files
  73         that match the specified paths came to be.  See "History
  74         Simplification" below for details and other simplification
  75         modes.
  76 +
  77 To prevent confusion with options and branch names, paths may need to
  78 be prefixed with "\-- " to separate them from options or refnames.

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

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