They will be run sequentially, yes. > i have seen people put && after an executable what is it for?

This makes sure you don't delete the files in the current directory if /tmp doesn't exist ;-) --mwest@cs.uct.ac.za http://www.cs.uct.ac.za To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
