Taming the power switch?

[ab1jx]

I'd like to redefine the power switch so it brings up a whiptail confirmation dialog or something like that before it actually shuts off.  Suspend could easily be added to that as another choice.

Is that possible?  I keep hitting it by accident.  I'm using the original Debian Stretch still.  Something like:

Code:

#!/bin/bash

TERM=ansi whiptail --title "Power button" --menu "Power Button" 8 20 5 \
"Turn off" "" \
"Suspend" "" \
"Cancel" ""

choice=$?
if [ $choice = 0 ]; then
  echo "Shutting down"
  shutdown now
else
  if [ $choice = 1 ]; then
    echo "Suspending"
    # write this
  else
    echo "Cancelling"
  fi
fi
