I only use it for one-liners or a-few-liners now, for unixy data-munging. (I'd still recommend the book by Aho, Kernighan, and Weinberger, because it's full of great examples.) 20-25 years ago I wrote many more things in Awk, up to a Lisp interpreter and a parser generator; but Python/Ruby/etc. have replaced it.
