GITMAILMAP(5)                     Git Manual                     GITMAILMAP(5)

NAME
       gitmailmap - Map author/committer names and/or E-Mail addresses

SYNOPSIS
       $GIT_WORK_TREE/.mailmap

DESCRIPTION
       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 (see git-config(1)), it is used to map author and
       committer names and email addresses to canonical real names and email
       addresses.

SYNTAX
       The # character begins a comment to the end of line, blank lines are
       ignored.

       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.

       Both E-Mails and names are matched case-insensitively. For example this
       would also match the Commit Name <commit@email.xx> above:

           Proper Name <proper@email.xx> CoMmIt NaMe <CoMmIt@EmAiL.xX>

NOTES
       Git does not follow symbolic links when accessing a .mailmap file in
       the working tree. This keeps behavior consistent when the file is
       accessed from the index or a tree versus from the filesystem.

EXAMPLES
       Your history contains commits by two authors, Jane and Joe, whose names
       appear in the repository under several forms:

           Joe Developer <joe@example.com>
           Joe R. Developer <joe@example.com>
           Jane Doe <jane@example.com>
           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 .mailmap file to correct
       the names would look like:

           Joe R. Developer <joe@example.com>
           Jane Doe <jane@example.com>
           Jane Doe <jane@desktop.(none)>


       Note that there's no need to map the name for <jane@laptop.(none)> to
       only correct the names. However, leaving the obviously broken
       <jane@laptop.(none)> and <jane@desktop.(none)> E-Mails as-is is usually
       not what you want. A .mailmap file which also corrects those is:

           Joe R. Developer <joe@example.com>
           Jane Doe <jane@example.com> <jane@laptop.(none)>
           Jane Doe <jane@example.com> <jane@desktop.(none)>


       Finally, let's say that Joe and Jane shared an E-Mail address, but not
       a name, e.g. by having these two commits in the history generated by a
       bug reporting system. I.e. names appearing in history as:

           Joe <bugs@example.com>
           Jane <bugs@example.com>


       A full .mailmap file which also handles those cases (an addition of two
       lines to the above example) would be:

           Joe R. Developer <joe@example.com>
           Jane Doe <jane@example.com> <jane@laptop.(none)>
           Jane Doe <jane@example.com> <jane@desktop.(none)>
           Joe R. Developer <joe@example.com> Joe <bugs@example.com>
           Jane Doe <jane@example.com> Jane <bugs@example.com>
