Bulk-change the default branch for all your GitHub repos at once, from master to main (or another new default you choose).
Usage:
pip3 install -r requirements.txt
python3 run.py GITHUB_OWNER GITHUB_TOKEN [NEW_DEFAULT_BRANCH=main]
GITHUB_OWNER is your username, unless you want to change repos under an organization (in which case you should use the org name).
Get a token from your account settings. Make sure it has full repo permissions.
By default, the script ignores:
- Forks
- Archived repositories
- Repos where the default branch is already non-standard (e.g.
development). - Repos ending in
.github.io, because GitHub Pages has hardcoded branch names.
Side effects:
- Existing clones will need to be updated, with
git fetch && git checkout NEW_DEFAULT_BRANCH. - Open pull requests to the old branch will be closed.
- Branch protection rules, CIs, and other systems that exclicitly reference the old branch by name may need to be updated seperately.
- You may get @dependabot PRs on repos that haven't been updated recently and have outdated pinned dependencies.
