git shortlog [<options>] [<revision range>] [[--] <path>...] git log --pretty=short | git shortlog [<options>]
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.
Each pretty-printed commit will be rewrapped before it is shown.
If width is 0 (zero) then indent the lines of the output without wrapping them.
Paths may need to be prefixed with -- to separate them from options or the revision range, when confusion arises.
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 <email@example.com>
The more complex forms are:
which allows mailmap to replace only the email part of a commit, and:
which allows mailmap to replace both the name and the email of a commit matching the specified commit email address, and:
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 <firstname.lastname@example.org> Joe R. Developer <email@example.com> Jane Doe <firstname.lastname@example.org> 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:
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 <email@example.com> nick2 <firstname.lastname@example.org> nick2 <email@example.com> santa <firstname.lastname@example.org> claus <email@example.com> CTO <firstname.lastname@example.org>
Then you might want a .mailmap file that looks like:
<email@example.com> <firstname.lastname@example.org> Some Dude <email@example.com> nick1 <firstname.lastname@example.org> Other Author <email@example.com> nick2 <firstname.lastname@example.org> Other Author <email@example.com> <firstname.lastname@example.org> Santa Claus <email@example.com> <firstname.lastname@example.org>
