The lovely and humbling thing about this it was written 3 decades ago and the examples still work. Makes me think of another short elegant piece by Kenneth Church (?) called "Unix for Poets" which shows how to use core UNIX utils to work with text. Also from the mid to late 80s. Perl may have replaced sed and awk but they endure.
