  12 'git log' [<options>] [<revision-range>] [[--] <path>...]

  14 DESCRIPTION
  15 -----------
  16 Shows the commit logs.
  17
  18 :git-log: 1
  19 include::rev-list-description.txt[]
  20
  21 The command takes options applicable to the linkgit:git-rev-list[1]
  22 command to control what is shown and how, and options applicable to
  23 the linkgit:git-diff[1] command to control how the changes
  24 each commit introduces are shown.
  25
  26
  27 OPTIONS
  28 -------
  29
  30 --follow::
  31         Continue listing the history of a file beyond renames
  32         (works only for a single file).
  33
  34 --no-decorate::
  35 --decorate[=short|full|auto|no]::
  36         Print out the ref names of any commits that are shown. If 'short' is
  37         specified, the ref name prefixes 'refs/heads/', 'refs/tags/' and
  38         'refs/remotes/' will not be printed. If 'full' is specified, the
  39         full ref name (including prefix) will be printed. If 'auto' is
  40         specified, then if the output is going to a terminal, the ref names
  41         are shown as if 'short' were given, otherwise no ref names are
  42         shown. The option `--decorate` is short-hand for `--decorate=short`.
  43         Default to configuration value of `log.decorate` if configured,
  44         otherwise, `auto`.
  45
  46 --decorate-refs=<pattern>::
  47 --decorate-refs-exclude=<pattern>::
  48         For each candidate reference, do not use it for decoration if it
  49         matches any patterns given to `--decorate-refs-exclude` or if it
  50         doesn't match any of the patterns given to `--decorate-refs`. The
  51         `log.excludeDecoration` config option allows excluding refs from
  52         the decorations, but an explicit `--decorate-refs` pattern will
  53         override a match in `log.excludeDecoration`.
  54 +
  55 If none of these options or config settings are given, then references are
  56 used as decoration if they match `HEAD`, `refs/heads/`, `refs/remotes/`,
  57 `refs/stash/`, or `refs/tags/`.
  58
  59 --clear-decorations::
  60         When specified, this option clears all previous `--decorate-refs`
  61         or `--decorate-refs-exclude` options and relaxes the default
  62         decoration filter to include all references. This option is
  63         assumed if the config value `log.initialDecorationSet` is set to
  64         `all`.
  65
  66 --source::
  67         Print out the ref name given on the command line by which each
  68         commit was reached.
  69
  70 --[no-]mailmap::
  71 --[no-]use-mailmap::
  72         Use mailmap file to map author and committer names and email
  73         addresses to canonical real names and email addresses. See
  74         linkgit:git-shortlog[1].
  75
  76 --full-diff::
  77         Without this flag, `git log -p <path>...` shows commits that
  78         touch the specified paths, and diffs about the same specified
  79         paths.  With this, the full diff is shown for commits that touch
  80         the specified paths; this means that "<path>..." limits only
  81         commits, and doesn't limit diff for those commits.
  82 +
  83 Note that this affects all diff-based output types, e.g. those
  84 produced by `--stat`, etc.
  85
  86 --log-size::
  87         Include a line ``log size <number>'' in the output for each commit,
  88         where <number> is the length of that commit's message in bytes.
  89         Intended to speed up tools that read log messages from `git log`
  90         output by allowing them to allocate space in advance.
  91
  92 include::line-range-options.txt[]
  93
  94 <revision-range>::
  95         Show only commits in the specified revision range.  When no
  96         <revision-range> is specified, it defaults to `HEAD` (i.e. the
  97         whole history leading to the current commit).  `origin..HEAD`
  98         specifies all the commits reachable from the current commit
  99         (i.e. `HEAD`), but not from `origin`. For a complete list of
 100         ways to spell <revision-range>, see the 'Specifying Ranges'
 101         section of linkgit:gitrevisions[7].
 102
 103 [--] <path>...::
 104         Show only commits that are enough to explain how the files
 105         that match the specified paths came to be.  See 'History
 106         Simplification' below for details and other simplification
 107         modes.
 108 +
 109 Paths may need to be prefixed with `--` to separate them from
 110 options or the revision range, when confusion arises.

 116 DIFF FORMATTING
 117 ---------------
 118
 119 By default, `git log` does not generate any diff output. The options
 120 below can be used to show the changes made by each commit.
 121
 122 Note that unless one of `--diff-merges` variants (including short
 123 `-m`, `-c`, `--cc`, and `--dd` options) is explicitly given, merge commits
 124 will not show a diff, even if a diff format like `--patch` is
 125 selected, nor will they match search options like `-S`. The exception
 126 is when `--first-parent` is in use, in which case `first-parent` is
 127 the default format for merge commits.

 134
 135 EXAMPLES
 136 --------
 137 `git log --no-merges`::
 138
 139         Show the whole commit history, but skip any merges
 140
 141 `git log v2.6.12.. include/scsi drivers/scsi`::
 142
 143         Show all commits since version 'v2.6.12' that changed any file
 144         in the `include/scsi` or `drivers/scsi` subdirectories
 145
 146 `git log --since="2 weeks ago" -- gitk`::
 147
 148         Show the changes during the last two weeks to the file 'gitk'.
 149         The `--` is necessary to avoid confusion with the *branch* named
 150         'gitk'
 151
 152 `git log --name-status release..test`::
 153
 154         Show the commits that are in the "test" branch but not yet
 155         in the "release" branch, along with the list of paths
 156         each commit modifies.
 157
 158 `git log --follow builtin/rev-list.c`::
 159
 160         Shows the commits that changed `builtin/rev-list.c`, including
 161         those commits that occurred before the file was given its
 162         present name.
 163
 164 `git log --branches --not --remotes=origin`::
 165
 166         Shows all commits that are in any of local branches but not in
 167         any of remote-tracking branches for 'origin' (what you have that
 168         origin doesn't).
 169
 170 `git log master --not --remotes=*/master`::
 171
 172         Shows all commits that are in local master but not in any remote
 173         repository master branches.
 174
 175 `git log -p -m --first-parent`::
 176
 177         Shows the history including change diffs, but only from the
 178         ``main branch'' perspective, skipping commits that come from merged
 179         branches, and showing full diffs of changes introduced by the merges.
 180         This makes sense only when following a strict policy of merging all
 181         topic branches when staying on a single integration branch.
 182
 183 `git log -L '/int main/',/^}/:main.c`::
 184
 185         Shows how the function `main()` in the file `main.c` evolved
 186         over time.
 187
 188 `git log -3`::
 189
 190         Limits the number of commits to show to 3.
