Hmm. With this tool if there's a pipe and no user-supplied files, I just put "-" onto the list of files to search -- using the 2-arg open. Someone suggested that was a bad idea, so I switched to the 3-arg open but that broke reading off the pipe. So is it right that in order to read off the pipe *and* be safe, I have to have both types of "open" statements in my code? - Bryan -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
