Delete username from a Git repository

If you want to replace the wrong ones with the proper one:

git config --global --replace-all user.name "FName LName"

same applies for user mail:

git config --global --replace-all user.mail "[email protected]"

Use git config -e and you should see something like:

[user]
    name = Shani
    name = shani
    name = shani

Delete the lines you don't want.

This worked for me on my Mac:

git config --global --unset-all user.name
