Another fix for shutting down simulators

# Ensure stray simulators are not still running

ps -ef | grep kinetic-simulator | grep -v 'grep' | tr -s ' ' | cut -d ' ' -f 2 | xargs kill $1

KINETIC_SIM = `ps -ef | grep kinetic-simulator | grep -v 'grep' | tr -s ' ' | cut -d ' ' -f 2`

if [! -z "$KINETIC_SIM" ]; then

  echo Killing kinetic-simulator w/ PID: $KINETIC_SIM

  kill $KINETIC_SIM

  echo Killed all kinetic simulators!

else

  echo No kinetic simulators alive to kill.
