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.
Read contacts, one per line, from the standard input after exhausting contacts provided on the command-line.
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.
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].
