Discourage use of mac during off hours by putting it to sleep automatically once a minute if it's awake

sleep.sh

#!/bin/bash
if test $(date '+%H') -ge 22 || test $(date '+%H') -le 5; then
	if expr $(date '+%M') % 2 && /usr/local/bin/brightness -l|grep -q 'active, awake, online'; then
		cvol=$(osascript -e 'output volume of (get volume settings)')
		#curb=$(brightness -l|tail -1|cut -d' ' -f4)
		finishat=$(expr $(date '+%s') + 60)
		while test $(date '+%s') -lt $finishat; do
			#brightness 0
			osascript -e "set volume output volume 0"
			pmset displaysleepnow
			sleep 0.3
		done
		osascript -e "set volume output volume $cvol"
		#brightness $curb
