It's an excellent companion piece to the more broadly focused second edition. This book provides complete coverage of the gawk 3.1 language as well as the most up-to-date coverage of the POSIX standard forawk available anywhere. Author Arnold Robbins clearly distinguishes standard awk features from GNU awk(gawk)-specific features, shines light into many of the "dark corners" of the language (areas to watch out for when programming), and devotes two full ch | ||
