To run use:

chmod +x remove-heroku-cli.py
sudo ./remove-heroku-cli.py

or 

sudo python3 remove-heroku-cli.py

SUDO is needed, without superuser access we can't remove some files and heroku cli configs

• This script will not remove plugins and files from vim, oh-my-zsh, and other files created by user, unless if these files are in any target directories.

• Be Careful, use this script if you know what are you doing, maybe it can break other stuffs that you might want to use
