# Suppose you want to do blind reviewing of code (eg for job interview
# purposes). Unfortunately, the candidates' names and email addresses are
# stored on every commit! You probably want to assess each candidate's version
# control practices, so just `rm -rf .git` throws away too much information.
# Here's what you can do instead.

#At first clone a repo with --bare option.

# Rewrite all commits to hide the author's name and email
git filter-branch -f --env-filter '
	export GIT_AUTHOR_NAME="Anonymous Developer"
	export GIT_AUTHOR_EMAIL="anon@example.com"
	export GIT_COMMITTER_NAME="Anonymous Developer"
	export GIT_COMMITTER_EMAIL="anon@example.com"' --tag-name-filter cat -- --branches --tags

# Delete remotes, which might point to the old commits
for r in `git remote`; do git remote rm $r; done
