NAME
git-shortlog - Summarize 'git log' output
SYNOPSIS
git log --pretty=short | git shortlog [<options>]
git shortlog [<options>] [<revision range>] [[--] <path>...]
DESCRIPTION
Summarizes git log output in a format suitable for inclusion in release announcements. Each commit will
be grouped by author and title.
Additionally, "[PATCH]" will be stripped from the commit description.
If no revisions are passed on the command line and either standard input is not a terminal or there is no
current branch, git shortlog will output a summary of the log read from standard input, without reference
to the current repository.
OPTIONS
-n, --numbered
Sort output according to the number of commits per author instead of author alphabetic order.
-s, --summary
Suppress commit description and provide a commit count summary only.
-e, --email
Show the email address of each author.
--format[=<format>]
Instead of the commit subject, use some other information to describe each commit. <format> can be
any string accepted by the --format option of git log, such as * [%h] %s. (See the "PRETTY FORMATS"
section of git-log(1).)
Each pretty-printed commit will be rewrapped before it is shown.
-w[<width>[,<indent1>[,<indent2>]]]
Linewrap the output by wrapping each line at width. The first line of each entry is indented by
indent1 spaces, and the second and subsequent lines are indented by indent2 spaces. width, indent1,
and indent2 default to 76, 6 and 9 respectively.
If width is 0 (zero) then indent the lines of the output without wrapping them.
<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 gitrevisions(7).
[--] <path>...
Consider only commits that are enough to explain how the files that match the specified paths came to
be.
Paths may need to be prefixed with "-- " to separate them from options or the revision range, when
confusion arises.
MAPPING AUTHORS
The .mailmap feature is used to coalesce together commits by the same person in the shortlog, where their
name and/or email address was spelled differently.
If the file .mailmap exists at the toplevel of the repository, or at the location pointed to by the
mailmap.file or mailmap.blob configuration options, it is used to map author and committer names and
email addresses to canonical real names and email addresses.
In the simple form, each line in the file consists of the canonical real name of an author, whitespace,
and an email address used in the commit (enclosed by < and >) to map to the name. For example:
Proper Name <commit@email.xx>
The more complex forms are:
<proper@email.xx> <commit@email.xx>
which allows mailmap to replace only the email part of a commit, and:
Proper Name <proper@email.xx> <commit@email.xx>
which allows mailmap to replace both the name and the email of a commit matching the specified commit
email address, and:
Proper Name <proper@email.xx> Commit Name <commit@email.xx>
which allows mailmap to replace both the name and the email of a commit matching both the specified
commit name and email address.
Example 1: Your history contains commits by two authors, Jane and Joe, whose names appear in the
repository under several forms:
Joe Developer <joe@example.com>
Joe R. Developer <joe@example.com>
Jane Doe <jane@example.com>
Jane Doe <jane@laptop.(none)>
Jane D. <jane@desktop.(none)>
Now suppose that Joe wants his middle name initial used, and Jane prefers her family name fully spelled
out. A proper .mailmap file would look like:
Jane Doe <jane@desktop.(none)>
Joe R. Developer <joe@example.com>
Note how there is no need for an entry for <jane@laptop.(none)>, because the real name of that author is
already correct.
Example 2: Your repository contains commits from the following authors:
nick1 <bugs@company.xx>
nick2 <bugs@company.xx>
nick2 <nick2@company.xx>
santa <me@company.xx>
claus <me@company.xx>
CTO <cto@coompany.xx>
Then you might want a .mailmap file that looks like:
<cto@company.xx> <cto@coompany.xx>
Some Dude <some@dude.xx> nick1 <bugs@company.xx>
Other Author <other@author.xx> nick2 <bugs@company.xx>
Other Author <other@author.xx> <nick2@company.xx>
Santa Claus <santa.claus@northpole.xx> <me@company.xx>
Use hash # for comments that are either on their own line, or after the email address.
