Completely reset a git repository. I found this useful when testing external scripts etc. on a repo that modify and create files. Only use this if you're really sure you want to get rid of all your local changes.

hard-reset-and-clean.sh

# Added this prompt for safety's sake in case you wanted to add this to your profile
while true; do
    read -p "Are your sure you want to completely reset your repository, including untracked files? (y/N) " yn
    yn=${yn:-N}
    case "$yn" in
        [Yy]* ) break;;
        [Nn]* ) exit;;
    esac
done

# Or just copy this line but only use this if you're really sure you want to get rid of all your local changes.
git reset --hard && git clean -fd
