I'm working on script meant to start/stop a set of services. For stopping, it has to terminate many processes which take a while and might hang.

The script needs to verify that the process has indeed terminated, and send an email if such does not happen after a given period.

This is what I have:

pkill -f "stuff"

for i in {1..30}; do
    VERIFICATIONS=$i
    if verification_command then
        echo "It's gone"
        break
    fi
    sleep 2
done

if [ $VERIFICATIONS -ge 30 ]; then
   echo "failed to terminate"
   # send mail
fi

Is there a better way to do this?
