ok.... If it's a small file, try Tie::File by (I believe) Mark Jason Dominus. It's very cool. For a big file, I'm not sure there's a better way than to just run through and count lines as you go....and I don't just mean for Perl. Lines are delimited by newline characters, and can be of varying lengths, so how else would you could them? You could do something like reading the whole file in by blocks and using m// or tr/// to count the newlines, but that's still pretty intensive. __________________________________________________ Do you Yahoo!?
