NAME         top

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

SYNOPSIS         top

       git check-mailmap [options] <contact>...

DESCRIPTION         top

       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.

OPTIONS         top

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

OUTPUT         top

       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.


       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 <commit@email.xx>

       The more complex forms are:

           <proper@email.xx> <commit@email.xx>

       which allows mailmap to replace only the email part of a commit, and:

           Proper Name <proper@email.xx> <commit@email.xx>

       which allows mailmap to replace both the name and the email of a
       commit matching the specified commit email address, and:

           Proper Name <proper@email.xx> Commit Name <commit@email.xx>

       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@laptop.(none)>
           Jane D. <jane@desktop.(none)>

       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         <jane@desktop.(none)>
           Joe R. Developer <>

       Note how there is no need for an entry for <jane@laptop.(none)>,
       because the real name of that author is already correct.

       Example 2: Your repository contains commits from the following

           nick1 <bugs@company.xx>
           nick2 <bugs@company.xx>
           nick2 <nick2@company.xx>
           santa <me@company.xx>
           claus <me@company.xx>
           CTO <cto@coompany.xx>

       Then you might want a .mailmap file that looks like:

           <cto@company.xx>                       <cto@coompany.xx>
           Some Dude <some@dude.xx>         nick1 <bugs@company.xx>
           Other Author <other@author.xx>   nick2 <bugs@company.xx>
           Other Author <other@author.xx>         <nick2@company.xx>
           Santa Claus <santa.claus@northpole.xx> <me@company.xx>

       Use hash # for comments that are either on their own line, or after
       the email address.
