Git pre-push hook to prevent accidentally pushing to shared repo

pre-push

#!/usr/bin/python
#
# Pre-push hook which aborts the push if it does not find current user's username in the remote path.
# To set up, copy into a folder of git hooks and mark as executable. To apply globally (starting with Git v2.9)
# use:
#     git config --global core.hooksPath=/path/to/hooks

    msg = 'WARNING: {} looks like a shared repo. Aborting push. To disable hooks pass --no-verify'.format(remote_name)
    print(msg)
