git-check-mailmap - Show canonical names and email addresses of contacts

git check-mailmap [<options>] <contact>…​

For each “Name <user@host>”, “<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.

--mailmap-file=<file>

In addition to any configured mailmap files, read the specified mailmap file. Entries in this file take precedence over entries in either the default mailmap file or any configured mailmap file.

--mailmap-blob=<blob>

Like --mailmap-file, but consider the value as a reference to a blob in the repository. If both --mailmap-file and --mailmap-blob are specified, entries in --mailmap-file will take precedence.

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.

See gitmailmap[5].
