power off switch / accessing GPIOs

[KHB49]

did it!
new install of moOde
sudo apt-get update
sudo apt upgrade
sudo apt autoremove
sudo apt install python3-gpiozero
sudo nano shutdown-press-simple.py
sudo chmod a+x shutdown-press-simple.py
sudo echo '~pi/shutdown-press-simple.py &'
sudo nano /etc/rc.local -> control the entry is before exit 0
done  did use the shutdown&hold script but did not change the name.
