Effective awk Programming, 3rd Edition
Text Processing and Pattern Matching
Effective awk Programming delivers complete coverage of the gawk 3.1 language and the most up-to-date coverage of the POSIX standard for awk 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, and devotes two full chapters to example programs. A brand new chapter is devoted to TCP/IP networking with gawk. This book is the official "User's Guide" for the GNU implementation of awk.
