GIT-CHECK-MAILMAP(1) Git Manual GIT-CHECK-MAILMAP(1)
NAME
git-check-mailmap - Show canonical names and email addresses of contacts
SYNOPSIS
git check-mailmap [options] ...
DESCRIPTION
For each “Name ” or “” from the command-line or standard input (when
using --stdin), look up the person’s canonical name and email address (see "Mapping
Authors" below). If found, print them; otherwise print the input as-is.
OPTIONS
--stdin
Read contacts, one per line, from the standard input after exhausting contacts
provided on the command-line.
OUTPUT
For each contact, a single line is output, terminated by a newline. If the name is
provided or known to the mailmap, “Name ” is printed; otherwise only
“” is printed.
MAPPING AUTHORS
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
The more complex forms are:
which allows mailmap to replace only the email part of a commit, and:
Proper Name
which allows mailmap to replace both the name and the email of a commit matching the
specified commit email address, and:
Proper Name Commit Name
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 R. Developer
Jane Doe
Jane Doe
Jane D.
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
Joe R. Developer
Note how there is no need for an entry for , because the real name of
that author is already correct.
Example 2: Your repository contains commits from the following authors:
nick1
nick2
nick2
santa
claus
CTO
Then you might want a .mailmap file that looks like:
Some Dude nick1
Other Author nick2
Other Author
Santa Claus
Use hash # for comments that are either on their own line, or after the email address.
