kill -15 $PID || exit 0
sleep 2
kill -2 $PID || exit 0
sleep 2
kill -1 $PID || exit 0
sleep 2
kill -9 $PID || exit 0

Now you have a PID for the image you can even monitor and program reactions (like restarting a service) if something goes wrong with it (no PID, not opening connections in a port, etc).

Monit can do that for you (http://mmonit.com/monit/).

Thanks to all of you. Now I have these 2 beautiful scripts:

startMyApp.sh:


#!/bin/sh
#settings
NOHUP="/usr/bin/nohup"
VM="/home/mariano/squeak/expury/build/squeak"
# Para produccion, como no van a estar las X, tengo que poner el -vm-display-null
VM_PARAMS="-mmap 200m -vm-sound-null"
IMAGE="destinoMochila.image"
#start the vm
$NOHUP "$VM" $VM_PARAMS "$IMAGE" &
# store in a file the PID of squeakVM
echo $! > evince.pid


stopMyApp.sh:

#!/bin/bash
PID=`cat evince.pid`
kill -15 $PID || exit 0
sleep 2
kill -2 $PID || exit 0
sleep 2
kill -1 $PID || exit 0
sleep 2
kill -9 $PID || exit 0


Thanks for the help!

Mariano
