I am aware of that. I don't see what you mean by that comment given the question and how it's relevant. "trap -- - HUP" means the disposition for HUP is SIG_DFL, which is suprising, given that nohup makes it ignored. bash that reports "trap -- '' HUP" tells that the disposition for HUP is SIG_IGN, as expected under nohup. -uwe
