-'git log' [<options>] [<since>..<until>] [[\--] <path>...]

DESCRIPTION
-----------
Shows the commit logs.
-The command takes options applicable to the 'git rev-list'
+:git-log: 1
+include::rev-list-description.txt[]

+The command takes options applicable to the linkgit:git-rev-list[1]
command to control what is shown and how, and options applicable to
-the 'git diff-*' commands to control how the changes
+the linkgit:git-diff[1] command to control how the changes
each commit introduces are shown.
OPTIONS
-------
-<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 linkgit:gitrevisions[7].

--follow::
Continue listing the history of a file beyond renames
(works only for a single file).
--no-decorate::
---decorate[=short|full|no]::
+--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. The default option
- is 'short'.
+ 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 option `--decorate` is short-hand for `--decorate=short`.
+ Default to configuration value of `log.decorate` if configured,
+ otherwise, `auto`.
+
+--decorate-refs=<pattern>::
+--decorate-refs-exclude=<pattern>::
+ If no `--decorate-refs` is given, pretend as if all refs were
+ included. For each candidate, do not use it for decoration if it
+ matches any patterns given to `--decorate-refs-exclude` or if it
+ doesn't match any of the patterns given to `--decorate-refs`. The
+ `log.excludeDecoration` config option allows excluding refs from
+ the decorations, but an explicit `--decorate-refs` pattern will
+ override a match in `log.excludeDecoration`.
--source::
Print out the ref name given on the command line by which each
commit was reached.
+--[no-]mailmap::
+--[no-]use-mailmap::
+ Use mailmap file to map author and committer names and email
+ addresses to canonical real names and email addresses. See

+ Without this flag, `git log -p <path>...` shows commits that

--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.
-
-[\--] <path>...::
+ 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.
+
+include::line-range-options.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 are enough to explain how the files
- that match the specified paths came to be. See "History
- Simplification" below for details and other simplification
+ that match the specified paths came to be. See 'History
+ Simplification' below for details and other simplification
modes.

-To prevent confusion with options and branch names, paths may need to
-be prefixed with "\-- " to separate them from options or refnames.
+Paths may need to be prefixed with `--` to separate them from
+options or the revision range, when confusion arises.

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