SYNOPSIS

-'git log' [<options>] [<since>..<until>] [[\--] <path>...]
+[verse]
+'git log' [<options>] [<revision range>] [[\--] <path>...]
DESCRIPTION
-----------
Shows the commit logs.
-The command takes options applicable to the 'git-rev-list'
+The command takes options applicable to the `git rev-list`
command to control what is shown and how, and options applicable to
-the 'git-diff-*' commands to control how the changes
+the `git diff-*` commands to control how the changes
each commit introduces are shown.
OPTIONS
-------
-:git-log: 1
-include::diff-options.txt[]
-
--<n>::
- Limits the number of commits to show.
-
-<since>..<until>::
- Show only commits between the named two commits. When
- either <since> or <until> is omitted, it defaults to
- `HEAD`, i.e. the tip of the current branch.
- For a more complete list of ways to spell <since>
- and <until>, see "SPECIFYING REVISIONS" section in
- linkgit:git-rev-parse[1].
-
---decorate::
- Print out the ref names of any commits that are shown.
+--follow::
+ Continue listing the history of a file beyond renames
+ (works only for a single file).
+
+--no-decorate::
+--decorate[=short|full|auto|no]::
+ Print out the ref names of any commits that are shown. If 'short' is
+ specified, the ref name prefixes 'refs/heads/', 'refs/tags/' and
+ 'refs/remotes/' will not be printed. If 'full' is specified, the
+ full ref name (including prefix) will be printed. If 'auto' is
+ specified, then if the output is going to a terminal, the ref names
+ are shown as if 'short' were given, otherwise no ref names are
+ shown. The default option is 'short'.
--source::
Print out the ref name given on the command line by which each
commit was reached.
+--use-mailmap::
+ Use mailmap file to map author and committer names and email
+ addresses to canonical real names and email addresses. See
+ linkgit:git-shortlog[1].
+
--full-diff::
- Without this flag, "git log -p <path>..." shows commits that
+ Without this flag, `git log -p <path>...` shows commits that
touch the specified paths, and diffs about the same specified
paths. With this, the full diff is shown for commits that touch
the specified paths; this means that "<path>..." limits only
commits, and doesn't limit diff for those commits.
-
---follow::
- Continue listing the history of a file beyond renames.
++
+Note that this affects all diff-based output types, e.g. those
+produced by `--stat`, etc.
--log-size::
- Before the log message print out its size in bytes. Intended
- mainly for porcelain tools consumption. If git is unable to
- produce a valid value size is set to zero.
- Note that only message is considered, if also a diff is shown
- its size is not included.
+ Include a line ``log size <number>'' in the output for each commit,
+ where <number> is the length of that commit's message in bytes.
+ Intended to speed up tools that read log messages from `git log`
+ output by allowing them to allocate space in advance.
+
+-L <start>,<end>:<file>::
+-L :<funcname>:<file>::
+ Trace the evolution of the line range given by "<start>,<end>"
+ (or the function name regex <funcname>) within the <file>. You may
+ not give any pathspec limiters. This is currently limited to
+ a walk starting from a single revision, i.e., you may only
+ give zero or one positive revision arguments.
+ You can specify this option more than once.
++
+include::line-range-format.txt[]
+
+<revision range>::
+ Show only commits in the specified revision range. When no
+ <revision range> is specified, it defaults to `HEAD` (i.e. the
+ whole history leading to the current commit). `origin..HEAD`
+ specifies all the commits reachable from the current commit
+ (i.e. `HEAD`), but not from `origin`. For a complete list of
+ ways to spell <revision range>, see the 'Specifying Ranges'
+ section of linkgit:gitrevisions[7].
[\--] <path>...::
- Show only commits that affect any of the specified paths. To
- prevent confusion with options and branch names, paths may need
- to be prefixed with "\-- " to separate them from options or
- refnames.
-
+ Show only commits that are enough to explain how the files
+ that match the specified paths came to be. See 'History
+ Simplification' below for details and other simplification
+ modes.
++
+Paths may need to be prefixed with ``\-- '' to separate them from
+options or the revision range, when confusion arises.

-Examples
+EXAMPLES
--------
-git log --no-merges::
+`git log --no-merges`::
Show the whole commit history, but skip any merges
-git log v2.6.12.. include/scsi drivers/scsi::
+`git log v2.6.12.. include/scsi drivers/scsi`::
Show all commits since version 'v2.6.12' that changed any file
- in the include/scsi or drivers/scsi subdirectories
+ in the `include/scsi` or `drivers/scsi` subdirectories
-git log --since="2 weeks ago" \-- gitk::
+`git log --since="2 weeks ago" -- gitk`::
Show the changes during the last two weeks to the file 'gitk'.
- The "--" is necessary to avoid confusion with the *branch* named
+ The ``--'' is necessary to avoid confusion with the *branch* named
'gitk'
-git log --name-status release..test::
+`git log --name-status release..test`::
Show the commits that are in the "test" branch but not yet
in the "release" branch, along with the list of paths
each commit modifies.
-git log --follow builtin-rev-list.c::
+`git log --follow builtin/rev-list.c`::
- Shows the commits that changed builtin-rev-list.c, including
+ Shows the commits that changed `builtin/rev-list.c`, including
those commits that occurred before the file was given its
present name.
-Discussion
-----------
+`git log --branches --not --remotes=origin`::
-include::i18n.txt[]
+ Shows all commits that are in any of local branches but not in
+ any of remote-tracking branches for 'origin' (what you have that
+ origin doesn't).
+
+`git log master --not --remotes=*/master`::
+
+ Shows all commits that are in local master but not in any remote
+ repository master branches.
+
+`git log -p -m --first-parent`::
+
+ Shows the history including change diffs, but only from the
+ ``main branch'' perspective, skipping commits that come from merged
+ branches, and showing full diffs of changes introduced by the merges.
+ This makes sense only when following a strict policy of merging all
+ topic branches when staying on a single integration branch.
+`git log -L '/int main/',/^}/:main.c`::
-Author
-------
-Written by Linus Torvalds <torvalds@osdl.org>
+ Shows how the function `main()` in the file `main.c` evolved
+ over time.
+
+`git log -3`::
+
+ Limits the number of commits to show to 3.

+CONFIGURATION
+-------------
+
+See linkgit:git-config[1] for core variables and linkgit:git-diff[1]
+for settings related to diff generation.
+
+format.pretty::
+ Default for the `--format` option. (See 'Pretty Formats' above.)
+ Defaults to `medium`.
+
+i18n.logOutputEncoding::
+ Encoding to use when displaying logs. (See 'Discussion' above.)
+ Defaults to the value of `i18n.commitEncoding` if set, and UTF-8
+ otherwise.
+
+log.date::
+ Default format for human-readable dates. (Compare the
+ `--date` option.) Defaults to "default", which means to write
+ dates like `Sat May 8 19:35:34 2010 -0500`.
+
+log.follow::
+ If `true`, `git log` will act as if the `--follow` option was used when
+ a single <path> is given. This has the same limitations as `--follow`,
+ i.e. it cannot be used to follow multiple files and does not work well
+ on non-linear history.
+
+log.showRoot::
+ If `false`, `git log` and related commands will not treat the
+ initial commit as a big creation event. Any root commits in
+ `git log -p` output would be shown without a diff attached.
+ The default is `true`.
+
+log.showSignature::
+ If `true`, `git log` and related commands will act as if the
+ `--show-signature` option was passed to them.
+
+mailmap.*::
+ See linkgit:git-shortlog[1].
+
+notes.displayRef::
+ Which refs, in addition to the default set by `core.notesRef`
+ or `GIT_NOTES_REF`, to read notes from when showing commit
+ messages with the `log` family of commands. See
+ linkgit:git-notes[1].
++
+May be an unabbreviated ref name or a glob and may be specified
+multiple times. A warning will be issued for refs that do not exist,
+but a glob that does not match any refs is silently ignored.
++
+This setting can be disabled by the `--no-notes` option,
+overridden by the `GIT_NOTES_DISPLAY_REF` environment variable,
+and overridden by the `--notes=<ref>` option.
