AWK is a text-processing language with a history spanning more than 40
years. It has a POSIX
standard, several conforming implementations, and is still surprisingly relevant in 2020 —
both for simple text processing tasks and for wrangling “big data”. The
recent
release
of
GNU Awk 5.1 seems like a good reason to survey the AWK landscape, see
what GNU Awk has been up to, and look at where AWK is being used these days.
