Say Alexa/Hey Google, turn off/on display

[Russ]

This script takes an on or off parameter that the Smart Home skill/action sends, so you can say things like this:

Alexa, turn off display
Alexa, turn on display
Hey Google, turn off display
Hey Google, turn on display

Don't forget to enable parameters, and to make the script executable with chmod +x display.sh

If you put the script in your home folder, you can run it with this command: ~/display.sh

#!/bin/bash
if [ "$1" == "off" ]
then
  echo turn display $1 >> /tmp/display_on_off.log
  pmset displaysleepnow
else
  echo turn computer $1 >> /tmp/display_on_off.log
  caffeinate -u -t 1
