# Do git add and commit with auto generated message. For laziness reasons 😂.
# It simply reads `git status -s`, converts the beginning M -> Update, A -> Add, and D -> Delete, and use it as a commit message.
# Example:
# git status: M  updated.txt
# generated message: Update updated.txt
#
# For debugging sed part:
# echo "M  updated.txt\nA  added.txt\nD  deleted.txt\nR  events/BaseEvents.yml -> events/AppEvents.yml" | sed "s/^M /Update/;s/^A /Add/;s/^D /Delete/;s/^R /Rename/;s/->/to/"
