   9SYNOPSIS
  10--------
  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-<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+
  61Note that this affects all diff-based output types, e.g. those
  62produced 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+
  77To prevent confusion with options and branch names, paths may need to
  78be prefixed with "\-- " to separate them from options or refnames.

  92Examples
  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.

 146Configuration
 147-------------
 148
 149See linkgit:git-config[1] for core variables and linkgit:git-diff[1]
 150for settings related to diff generation.
 151
 152format.pretty::
 153        Default for the `--format` option.  (See "PRETTY FORMATS" above.)
 154        Defaults to "medium".
 155
 156i18n.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
 161log.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
 166log.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
 172mailmap.file::
 173        See linkgit:git-shortlog[1].
 174
 175notes.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+
 181May be an unabbreviated ref name or a glob and may be specified
 182multiple times.  A warning will be issued for refs that do not exist,
 183but a glob that does not match any refs is silently ignored.
 184+
 185This setting can be disabled by the `--no-notes` option,
 186overridden by the 'GIT_NOTES_DISPLAY_REF' environment variable,
 187and overridden by the `--notes=<ref>` option.
