The shutdown script doesn't work for me. I get an error on line 5 which is the line: echo "$BUTTON" > /sys/class/gpio/export I get: "echo: write error: Device or resource busy" Of course lines 6 and 7 give errors also.

Any idea what this is (BTW, I'm running this on a Raspi 4 4GB with 7" Raspi display)
