Uninstall SFDX Pilot Binary

#!/bin/sh
# NOTE: The pilot version included the Heroku CLI. 
# Running the script will blow away ALL Heroku folders.
# You may need to reinstall the Heroku Toolbelt.

# NOTE: As with any script you download on the internet, 
# please make sure you understand what each command is
# going to do before running it.

rm -rf /usr/local/heroku
rm -rf /usr/local/sfdx
rm -rf /usr/local/lib/heroku
rm -rf /usr/local/lib/sfdx
rm -rf /usr/local/bin/heroku
rm -rf /usr/local/bin/sfdx
rm -rf ~/.local/share/heroku ~/.cache/heroku
rm -rf ~/.local/share/sfdx ~/.config/sfdx ~/.cache/sfdx

i'd recommend not running the heroku portions and just stripping the dx stuff first and see if that works for you, particularly if you also use heroku
