execute something/service in the background
and based on its exist status, execute something else

example
i have installed MySQL NDB cluster. It needs around 2-3 minutes to synchronise the database in between cluster nodes. Once the synchronisation finished only, I can start another application called heartbeat. Therefore in my shell script, I want to check the availability of the ndbd service all the times. Once this service become available, I need to start the heartbeat application


# send to background
./ndb_startup_script &
