a brief summary -
i would like to check if an application has completely stop running by checking the %cpu. this application when not running is not at 0.0. it idles around ~ 0.4. however, sometimes i see the cpu dips below 0.4 or sometimes 0.0 for a brief second, then rebound higher. so my logic below would echo 'stop running' then exit out of the loop (which is not true because it dips quickly then rebound).
i have the following script, but not working as intended:
while :
do
num1=$(ps aux | grep "Name_Of_App" | head -1 | awk '{print $3}')
num2=0.4
if (( $(echo "$num1 > $num2" | bc -l) ));
then
echo "running"
else
echo "not running"
break
fi
done
is there a better solution?
thanks
