Brian Kernighan recently told me that "Al and Peter and I" (that is, A, W, and K) are working on a second edition of the book "The AWK Programming Language". The first edition is excellent (it inspired me to write an AWK interpreter in Go). Anyway, I'm really looking forward to seeing what the second edition looks like. I think it'll help renew interest in AWK in general, and no doubt bring some of the examples up to date (though the book has aged very well!).
