  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-L <start>,<end>:<file>, -L :<regex>:<file>::
  66
  67        Trace the evolution of the line range given by "<start>,<end>"
  68        (or the funcname regex <regex>) within the <file>.  You may
  69        not give any pathspec limiters.  This is currently limited to
  70        a walk starting from a single revision, i.e., you may only
  71        give zero or one positive revision arguments.
  72        You can specify this option more than once.
  73+
  74<start> and <end> can take one of these forms:
  75
  76include::line-range-format.txt[]
  77
  78<revision range>::
  79        Show only commits in the specified revision range.  When no
  80        <revision range> is specified, it defaults to `HEAD` (i.e. the
  81        whole history leading to the current commit).  `origin..HEAD`
  82        specifies all the commits reachable from the current commit
  83        (i.e. `HEAD`), but not from `origin`. For a complete list of
  84        ways to spell <revision range>, see the "Specifying Ranges"
  85        section of linkgit:gitrevisions[7].
  86
  87[\--] <path>...::
  88        Show only commits that are enough to explain how the files
  89        that match the specified paths came to be.  See "History
  90        Simplification" below for details and other simplification
  91        modes.
  92+
  93Paths may need to be prefixed with "\-- " to separate them from
  94options or the revision range, when confusion arises.

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

 169Configuration
 170-------------
 171
 172See linkgit:git-config[1] for core variables and linkgit:git-diff[1]
 173for settings related to diff generation.
 174
 175format.pretty::
 176        Default for the `--format` option.  (See "PRETTY FORMATS" above.)
 177        Defaults to "medium".
 178
 179i18n.logOutputEncoding::
 180        Encoding to use when displaying logs.  (See "Discussion", above.)
 181        Defaults to the value of `i18n.commitEncoding` if set, UTF-8
 182        otherwise.
 183
 184log.date::
 185        Default format for human-readable dates.  (Compare the
 186        `--date` option.)  Defaults to "default", which means to write
 187        dates like `Sat May 8 19:35:34 2010 -0500`.
 188
 189log.showroot::
 190        If `false`, 'git log' and related commands will not treat the
 191        initial commit as a big creation event.  Any root commits in
 192        `git log -p` output would be shown without a diff attached.
 193        The default is `true`.
 194
 195mailmap.*::
 196        See linkgit:git-shortlog[1].
 197
 198notes.displayRef::
 199        Which refs, in addition to the default set by `core.notesRef`
 200        or 'GIT_NOTES_REF', to read notes from when showing commit
 201        messages with the 'log' family of commands.  See
 202        linkgit:git-notes[1].
 203+
 204May be an unabbreviated ref name or a glob and may be specified
 205multiple times.  A warning will be issued for refs that do not exist,
 206but a glob that does not match any refs is silently ignored.
 207+
 208This setting can be disabled by the `--no-notes` option,
 209overridden by the 'GIT_NOTES_DISPLAY_REF' environment variable,
 210and overridden by the `--notes=<ref>` option.
