Re: Deamon: Need Child to exit if parent dies

SIGKILL (9) cannot be trapped by a process - the OS just stops scheduling the process. You will need to have the child monitor the parent process to see if it still exists (perhaps with kill 0, ... (see kill), and take action based on that.

See also documentation for $PID, specifically the information about getppid.

Agreed. I would check to see if my parent ID changed to init (1). Then the child knows it became an orphan.	[reply]
