git-check-mailmap - Show canonical names and email addresses of contacts
git check-mailmap [<options>] <contact>...
For each “Name <user@host>” or
“<user@host>” 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.
--stdin
Read contacts, one per line, from the standard input
after exhausting contacts provided on the command-line.
For each contact, a single line is output, terminated by a newline. If the name
is provided or known to the mailmap, “Name
<user@host>” is printed; otherwise only
“<user@host>” is printed.
See mailmap.file and mailmap.blob in git-config(1) for how
to specify a custom .mailmap target file or object.
