  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        addresses 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        Include a line ``log size <number>'' in the output for each commit,
  60        where <number> is the length of that commit's message in bytes.
  61        Intended to speed up tools that read log messages from `git log`
  62        output by allowing them to allocate space in advance.
  63
  64-L <start>,<end>:<file>::
  65-L :<funcname>:<file>::
  66        Trace the evolution of the line range given by "<start>,<end>"
  67        (or the function name regex <funcname>) within the <file>.  You may
  68        not give any pathspec limiters.  This is currently limited to
  69        a walk starting from a single revision, i.e., you may only
  70        give zero or one positive revision arguments.
  71        You can specify this option more than once.
  72+
  73include::line-range-format.txt[]
  74
  75<revision range>::
  76        Show only commits in the specified revision range.  When no
  77        <revision range> is specified, it defaults to `HEAD` (i.e. the
  78        whole history leading to the current commit).  `origin..HEAD`
  79        specifies all the commits reachable from the current commit
  80        (i.e. `HEAD`), but not from `origin`. For a complete list of
  81        ways to spell <revision range>, see the 'Specifying Ranges'
  82        section of linkgit:gitrevisions[7].
  83
  84[\--] <path>...::
  85        Show only commits that are enough to explain how the files
  86        that match the specified paths came to be.  See 'History
  87        Simplification' below for details and other simplification
  88        modes.
  89+
  90Paths may need to be prefixed with ``\-- '' to separate them from
  91options or the revision range, when confusion arises.

 105EXAMPLES
 106--------
 107`git log --no-merges`::
 108
 109        Show the whole commit history, but skip any merges
 110
 111`git log v2.6.12.. include/scsi drivers/scsi`::
 112
 113        Show all commits since version 'v2.6.12' that changed any file
 114        in the `include/scsi` or `drivers/scsi` subdirectories
 115
 116`git log --since="2 weeks ago" -- gitk`::
 117
 118        Show the changes during the last two weeks to the file 'gitk'.
 119        The ``--'' is necessary to avoid confusion with the *branch* named
 120        'gitk'
 121
 122`git log --name-status release..test`::
 123
 124        Show the commits that are in the "test" branch but not yet
 125        in the "release" branch, along with the list of paths
 126        each commit modifies.
 127
 128`git log --follow builtin/rev-list.c`::
 129
 130        Shows the commits that changed `builtin/rev-list.c`, including
 131        those commits that occurred before the file was given its
 132        present name.
 133
 134`git log --branches --not --remotes=origin`::
 135
 136        Shows all commits that are in any of local branches but not in
 137        any of remote-tracking branches for 'origin' (what you have that
 138        origin doesn't).
 139
 140`git log master --not --remotes=*/master`::
 141
 142        Shows all commits that are in local master but not in any remote
 143        repository master branches.
 144
 145`git log -p -m --first-parent`::
 146
 147        Shows the history including change diffs, but only from the
 148        ``main branch'' perspective, skipping commits that come from merged
 149        branches, and showing full diffs of changes introduced by the merges.
 150        This makes sense only when following a strict policy of merging all
 151        topic branches when staying on a single integration branch.
 152
 153`git log -L '/int main/',/^}/:main.c`::
 154
 155        Shows how the function `main()` in the file `main.c` evolved
 156        over time.
 157
 158`git log -3`::
 159
 160        Limits the number of commits to show to 3.

 167CONFIGURATION
 168-------------
 169
 170See linkgit:git-config[1] for core variables and linkgit:git-diff[1]
 171for settings related to diff generation.
 172
 173format.pretty::
 174        Default for the `--format` option.  (See 'Pretty Formats' above.)
 175        Defaults to `medium`.
 176
 177i18n.logOutputEncoding::
 178        Encoding to use when displaying logs.  (See 'Discussion' above.)
 179        Defaults to the value of `i18n.commitEncoding` if set, and UTF-8
 180        otherwise.
 181
 182log.date::
 183        Default format for human-readable dates.  (Compare the
 184        `--date` option.)  Defaults to "default", which means to write
 185        dates like `Sat May 8 19:35:34 2010 -0500`.
 186
 187log.showRoot::
 188        If `false`, `git log` and related commands will not treat the
 189        initial commit as a big creation event.  Any root commits in
 190        `git log -p` output would be shown without a diff attached.
 191        The default is `true`.
 192
 193mailmap.*::
 194        See linkgit:git-shortlog[1].
 195
 196notes.displayRef::
 197        Which refs, in addition to the default set by `core.notesRef`
 198        or 'GIT_NOTES_REF', to read notes from when showing commit
 199        messages with the `log` family of commands.  See
 200        linkgit:git-notes[1].
 201+
 202May be an unabbreviated ref name or a glob and may be specified
 203multiple times.  A warning will be issued for refs that do not exist,
 204but a glob that does not match any refs is silently ignored.
 205+
 206This setting can be disabled by the `--no-notes` option,
 207overridden by the 'GIT_NOTES_DISPLAY_REF' environment variable,
 208and overridden by the `--notes=<ref>` option.
