Bash script to check a process output, then do something

Hi,

Looking for a script to do the following - start the program is its status is not running.
The program returns the string 'not running' if not running, else some other text :

status = /home/user/program getstatus
if (status == 'not running') {
  /home/user/program start
} else {
 // do nothing
}

Can someone help out please.

Thanks
BT
