Is there a way to override a git author's display name in local repository config?

Question

I have a git repository imported from subversion where users have names like H1234567. When I run git log or git blame I\'d prefer to see

Answer 1

You can do this with a mailmap file, which can translate authors' name and email without modifying history.

Create a file .mailmap at the repository root with the following:

dave     H1234567 

You can set different email address, or keep the original one.

See Documentation/mailmap.txt for more.
