  12'git log' [<options>] [<revision range>] [[\--] <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--follow::
  28        Continue listing the history of a file beyond renames
  29        (works only for a single file).
  30
  31--no-decorate::
  32--decorate[=short|full|no]::
  33        Print out the ref names of any commits that are shown. If 'short' is
  34        specified, the ref name prefixes 'refs/heads/', 'refs/tags/' and
  35        'refs/remotes/' will not be printed. If 'full' is specified, the
  36        full ref name (including prefix) will be printed. The default option
  37        is 'short'.
  38
  39--source::
  40        Print out the ref name given on the command line by which each
  41        commit was reached.
  42
  43--use-mailmap::
  44        Use mailmap file to map author and committer names and email
  45        to canonical real names and email addresses. See
  46        linkgit:git-shortlog[1].
  47
  48--full-diff::
  49        Without this flag, "git log -p <path>..." shows commits that
  50        touch the specified paths, and diffs about the same specified
  51        paths.  With this, the full diff is shown for commits that touch
  52        the specified paths; this means that "<path>..." limits only
  53        commits, and doesn't limit diff for those commits.
  54+
  55Note that this affects all diff-based output types, e.g. those
  56produced by --stat etc.
  57
  58--log-size::
  59        Before the log message print out its size in bytes. Intended
  60        mainly for porcelain tools consumption. If Git is unable to
  61        produce a valid value size is set to zero.
  62        Note that only message is considered, if also a diff is shown
  63        its size is not included.
  64
  65<revision range>::
  66        Show only commits in the specified revision range.  When no
  67        <revision range> is specified, it defaults to `HEAD` (i.e. the
  68        whole history leading to the current commit).  `origin..HEAD`
  69        specifies all the commits reachable from the current commit
  70        (i.e. `HEAD`), but not from `origin`. For a complete list of
  71        ways to spell <revision range>, see the "Specifying Ranges"
  72        section of linkgit:gitrevisions[7].
  73
  74[\--] <path>...::
  75        Show only commits that are enough to explain how the files
  76        that match the specified paths came to be.  See "History
  77        Simplification" below for details and other simplification
  78        modes.
  79+
  80Paths may need to be prefixed with "\-- " to separate them from
  81options or the revision range, when confusion arises.

  95Examples
  96--------
  97`git log --no-merges`::
  98
  99        Show the whole commit history, but skip any merges
 100
 101`git log v2.6.12.. include/scsi drivers/scsi`::
 102
 103        Show all commits since version 'v2.6.12' that changed any file
 104        in the include/scsi or drivers/scsi subdirectories
 105
 106`git log --since="2 weeks ago" -- gitk`::
 107
 108        Show the changes during the last two weeks to the file 'gitk'.
 109        The "--" is necessary to avoid confusion with the *branch* named
 110        'gitk'
 111
 112`git log --name-status release..test`::
 113
 114        Show the commits that are in the "test" branch but not yet
 115        in the "release" branch, along with the list of paths
 116        each commit modifies.
 117
 118`git log --follow builtin-rev-list.c`::
 119
 120        Shows the commits that changed builtin-rev-list.c, including
 121        those commits that occurred before the file was given its
 122        present name.
 123
 124`git log --branches --not --remotes=origin`::
 125
 126        Shows all commits that are in any of local branches but not in
 127        any of remote-tracking branches for 'origin' (what you have that
 128        origin doesn't).
 129
 130`git log master --not --remotes=*/master`::
 131
 132        Shows all commits that are in local master but not in any remote
 133        repository master branches.
 134
 135`git log -p -m --first-parent`::
 136
 137        Shows the history including change diffs, but only from the
 138        "main branch" perspective, skipping commits that come from merged
 139        branches, and showing full diffs of changes introduced by the merges.
 140        This makes sense only when following a strict policy of merging all
 141        topic branches when staying on a single integration branch.
 142
 143`git log -3`::
 144        Limits the number of commits to show to 3.

 151Configuration
 152-------------
 153
 154See linkgit:git-config[1] for core variables and linkgit:git-diff[1]
 155for settings related to diff generation.
 156
 157format.pretty::
 158        Default for the `--format` option.  (See "PRETTY FORMATS" above.)
 159        Defaults to "medium".
 160
 161i18n.logOutputEncoding::
 162        Encoding to use when displaying logs.  (See "Discussion", above.)
 163        Defaults to the value of `i18n.commitEncoding` if set, UTF-8
 164        otherwise.
 165
 166log.date::
 167        Default format for human-readable dates.  (Compare the
 168        `--date` option.)  Defaults to "default", which means to write
 169        dates like `Sat May 8 19:35:34 2010 -0500`.
 170
 171log.showroot::
 172        If `false`, 'git log' and related commands will not treat the
 173        initial commit as a big creation event.  Any root commits in
 174        `git log -p` output would be shown without a diff attached.
 175        The default is `true`.
 176
 177mailmap.*::
 178        See linkgit:git-shortlog[1].
 179
 180notes.displayRef::
 181        Which refs, in addition to the default set by `core.notesRef`
 182        or 'GIT_NOTES_REF', to read notes from when showing commit
 183        messages with the 'log' family of commands.  See
 184        linkgit:git-notes[1].
 185+
 186May be an unabbreviated ref name or a glob and may be specified
 187multiple times.  A warning will be issued for refs that do not exist,
 188but a glob that does not match any refs is silently ignored.
 189+
 190This setting can be disabled by the `--no-notes` option,
 191overridden by the 'GIT_NOTES_DISPLAY_REF' environment variable,
 192and overridden by the `--notes=<ref>` option.
