This is a script that changes the author and committer of several commits in a git repository. This is very dangerous and could mess up your repository. manually check everything before pushing changes.
Feed commit hashes through stdin. Each line must have this format:
COMMIT_HASH|AUTHOR_NAME|AUTHOR_EMAIL
This will update commit COMMIT_HASH to have author AUTHOR_NAME <AUTHOR_EMAIL. Commit date and author date is set to the author date.
If a merge conflict occurs, you have to resolve it and commit the changes. Make sure the resolution and merge commit is identical to the original merge commit. You will be prompted on how if one occurs.
An example execution can be:
# commits.txt
40c115a80c8edcd48a8bc4f1614a06967009b7e9|Person 1|[email protected]
b0c4374593324cb02cffcb428b2b2b4b18e563cf|Person 2|[email protected]

3fc62637c6443a5c4af9d22e9c42b1d8fb52d68d|Person 1|[email protected]
cat commits.txt | git-change-author
Note that commits.txt has to end in a single newline.
If you just want to set the committer and author to be the same, you can generate a commit list with git log --format="%H|%an|%ae"
