I didn't realize 'sort' had a -u option. Does that work on Solaris? For some reason I thought I had read that 'sort' and 'uniq' were both required for that task, but now that I look, that's clearly not the case with at least Linux and OpenBSD. And since I was piping anyway, I thought I'd start it with a 'cat' just so the train of thought was easy to follow (first you start with the file, then you sort it, then you look for unique lines). *shrug*
