Fair enough, someone else made similar point that I had GNU awk in mind wrt all of awk And yeah, it's possible to start using basic field processing and regexp features (if you already know it) in 2 hours and learn most of it in 2 weeks. But, that quote could've been something like you could get started in 2 hours instead of saying one could know all of awk.
