NAME

git-check-mailmap - Show canonical names and email addresses of contacts
7+
8+
9+
SYNOPSIS
10+
--------
11+
[verse]
12+
'git check-mailmap' [options] <contact>...
13+
14+
15+
DESCRIPTION
16+
-----------
17+
18+
For each ``Name $$<user@host>$$'' or ``$$<user@host>$$'' from the command-line
19+
or standard input (when using `--stdin`), look up the person's canonical name
20+
and email address (see "Mapping Authors" below). If found, print them;
21+
otherwise print the input as-is.
22+
23+
24+
OPTIONS
25+
-------
26+
--stdin::
27+
Read contacts, one per line, from the standard input after exhausting
28+
contacts provided on the command-line.
29+
30+
31+
OUTPUT
32+
------
33+
34+
For each contact, a single line is output, terminated by a newline. If the
35+
name is provided or known to the 'mailmap', ``Name $$<user@host>$$'' is
36+
printed; otherwise only ``$$<user@host>$$'' is printed.
