Try this: sed -n '/PATH/p' /etc/profile Compare that to the version without -n. There are many times where I don't want the default action to be print. If I were to think of it a little more I could come up with real examples of using it. sed -n '/^+/q;p' /etc/passwd sed -n '/^+/,$p' /etc/passwd [NIS/YP uses a line with a '+' to denote pulling in the mapfile right there in the middle of the file.] Bob
