[TriLUG] How to spawn separate process and get pid.

[Wesley Zhang]

Hi All,
I am a newbie on shell script. But I would like to use linux shell 
script to control a job that runs forever and will be terminated after 
10 minute. My thought for this is following:

 pid = start-job-for ("cmd") // has to be a separate process
 sleep 10 min
 kill pid.
How can I spawn a separate process to execute my command and get the 
proper process id?

Thanks,
Wesley
