http://www.linuxforums.org – So I think i got this down but i just wanted to make sure. OK: Login shell creates Bash shell. then when you go to start a proc. your bash shell creates a sub-shell which will run the proc. in order to kill the proc, because of how linux works, you kill the sub-shell. the reason you use a sub-shell is that if you were to run the proc directly from the initial bash shell, when you went to kill the proc it would kill your inital bash shell? any help would be much appreciated!
