What did you try? What didn't work? Why do you want it to be a 1-liner? The easiest way I see to do it would be using a flag to track whether you've seen the line in question and the -n and -i switches. So pretty much what LanX said. #11929 First ask yourself `How would I do this without a computer?' Then have the computer do it the same way.	[reply]

`perl -pi -e " exit if /#vgc config/" /etc/rc.local` The above works perfectly. Thank you PERL monks.	[reply] [d/l]
