  11[verse]
  12'git log' [<options>] [<since>..<until>] [[\--] <path>...]
  13
  14DESCRIPTION
  15-----------
  16Shows the commit logs.
  17
  18The command takes options applicable to the 'git rev-list'
  19command to control what is shown and how, and options applicable to
  20the 'git diff-*' commands to control how the changes
  21each commit introduces are shown.
  22
  23
  24OPTIONS
  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+
  62Note that this affects all diff-based output types, e.g. those
  63produced 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+
  78To prevent confusion with options and branch names, paths may need to
  79be prefixed with "\-- " to separate them from options or refnames.

  93Examples
  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.

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