Do NOT run this unless you are prepared to reboot. :-(

When I ran the code below....

test.sh 5
Max runtime exceeded, killing PID 2749
/home/andy/bin/test.sh: line 30: 2749 Killed $command > /dev/null 2> /dev/null
Killed.

Code:

command="/usr/bin/stress --cpu 8 --io 4 --vm 2 --vm-bytes 128M"

maxruntime=$1

$command >/dev/null 2>/dev/null &
watchpid=$!

/bin/sleep "$maxruntime"

if [ -d "/proc/$watchpid" ]
then
        echo "Max runtime exceeded, killing PID $watchpid"

        if /bin/kill -9 "$watchpid" >/dev/null 2>/dev/null
        then
                echo "Killed."
                exit 0
        else
                echo "Could not kill, please investigate manually."
                exit 1
        fi
fi

If you are gonna slice haberno peppers, either use gloves or wash hands 3 times. I forgot and rubbed my eyes.
