Remove a password from Git's history

gistfile1.sh

# Sync with the remote master
git pull

# Force your clone to look like HEAD
git reset --hard

# AGAIN, A WARNING: This can really break stuff!

# Run your filter branch command, replacing all instances of "password" with "your_password"
# The example looks for Ruby files ("*.rb"), you can change this to match your needs
git filter-branch --tree-filter 'git ls-files -z "*.rb" |xargs -0 perl -p -i -e "s#(password)#your_password#g"' -- --all

# Overwrite your master with local changes
git push origin master --force

This is a godsend. Thank you so much for putting this up! :)

Still useful all these years later 👍
