Don, good article. I've been there on the hiring side, not in security, but with system administration. I ran into a supposed MCSE that didn't know Windows had default hidden shares for every volume.
timmedin, you are so on the money about the people who are willing to admit they don't know something. Amazing how infrequently people fit this bill. Thanks for linking to the article with the find command. I haven't used xargs in some years. I'd have used 'grep -l' if asked.
I do remember having to use xargs in the old Solaris 6 and 7 days when the find that shipped with Solaris sucked so bad it wouldn't interpret some standard switches correctly. Hadn't thought about it in at least two or three years though.
