I'm quite sure I've asked a very similar question, but I just can't seem to make my thing work... I am going to execute a script through cron. When it is complete, I want it to execute itself again (then current one will die) in the background. How do I make it run in the BACKGROUND instead of the first one waiting for the output of the second execution to finish?
Of course, that requires that Safe Mode is on But it is a very good method. I just found another thread handling about this here.
