# This line doesn't work as expected
# It does not update with reduced git history size 
git push --force  https://github.com/brianspiering/intro_course_data_science_for_good-1.git

# If that does not work, another option is delete all git history
# Inspired by https://gist.github.com/stephenhardy/5470814

# Remove the history from 
rm -rf .git

# Recreate the repos from the current content only
git init --initial-branch=main
git add .
git commit -m "Initial commit"

# Push to the github remote repos ensuring you overwrite history
git remote add origin [email protected]:<YOUR ACCOUNT>/<YOUR REPOS>.git
git push -u --force origin main
