|
|
git-log - Show commit logs
|

|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'git log' [<options>] [<revision-range>] [[--] <path>...]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
Shows the commit logs.
|
|
|
|
: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 linkgit:git-diff[1] command to control how the changes
|
|
each commit introduces are shown.
|
|
|
|
|
|
OPTIONS
|
|
-------
|
|
|
|
--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 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>::
|
|
For each candidate reference, 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`.
|
|
+
|
|
If none of these options or config settings are given, then references are
|
|
used as decoration if they match `HEAD`, `refs/heads/`, `refs/remotes/`,
|
|
`refs/stash/`, or `refs/tags/`.
|
|
|
|
--clear-decorations::
|
|
When specified, this option clears all previous `--decorate-refs`
|
|
or `--decorate-refs-exclude` options and relaxes the default
|
|
decoration filter to include all references. This option is
|
|
assumed if the config value `log.initialDecorationSet` is set to
|
|
`all`.
|
|
|
|
--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
|
|
linkgit:git-shortlog[1].
|
|
|
|
--full-diff::
|
|
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.
|
|
+
|
|
Note that this affects all diff-based output types, e.g. those
|
|
produced by `--stat`, etc.
|
|
|
|
--log-size::
|
|
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
|
|
modes.
|
|
+
|
|
Paths may need to be prefixed with `--` to separate them from
|
|
options or the revision range, when confusion arises.

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`, `--cc`, and `--dd` 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 for merge commits.
|
|

EXAMPLES
|
|
--------
|
|
`git log --no-merges`::
|
|
|
|
Show the whole commit history, but skip any merges
|
|
|
|
`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
|
|
|
|
`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
|
|
'gitk'
|
|
|
|
`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`::
|
|
|
|
Shows the commits that changed `builtin/rev-list.c`, including
|
|
those commits that occurred before the file was given its
|
|
present name.
|
|
|
|
`git log --branches --not --remotes=origin`::
|
|
|
|
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`::
|
|
|
|
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.
