[git] How to change the author and committer name and e-mail of multiple commits in Git?

  1. Change commit author name & email by Amend, then replacing old-commit with new-one:

    $ git checkout <commit-hash>                            # checkout to the commit need to modify  
    $ git commit --amend --author "name <[email protected]>" # change the author name and email
    
    $ git replace <old-commit-hash> <new-commit-hash>      # replace the old commit by new one
    $ git filter-branch -- --all                           # rewrite all futures commits based on the replacement                   
    
    $ git replace -d <old-commit-hash>     # remove the replacement for cleanliness 
    $ git push -f origin HEAD              # force push 
    
  2. Another way Rebasing:

    $ git rebase -i <good-commit-hash>      # back to last good commit
    
    # Editor would open, replace 'pick' with 'edit' before the commit want to change author
    
    $ git commit --amend --author="author name <[email protected]>"  # change the author name & email
    
    # Save changes and exit the editor
    
    $ git rebase --continue                # finish the rebase
