Hello Perderabo,
---------------------------------------------------
"
I know that my method leaves a sleep process running if the timed command completes in time. I think that's harmless. It will be reaped by init when it exits. That's the only real cost of a very easily coded solution. Capturing and killing that last pid will drive script back up in complexity.
"
----------------------------------------------------

Does sleep process creates any kind of overhead for the unix system.

When I execute the following command (sleep 30; echo hello) &
, it create the two processes one is the shell process and the other is sleep process and the sleep process pid is always 1 greater than the shell process pid. Is it always true ?.
