Effective Awk Programming 3rd Edition
Effective awk Programming,3rd Edition, focuses entirely on awk, exploring it in the greatest depth of the three awk titles we carry. 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 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 (areas to watch out for when programming), and devotes two full chapters to example programs. A brand new chapter is devoted to TCP/IP networking with gawk. He includes a summary of how the awk language evolved.
The book also covers:
* Internationalization of gawk
* Interfacing to i18n at the awk level
* Two-way pipes
* TCP/IP networking via the two-way pipe interface
* The new PROCINFO array, which provides information about running gawk
* Profiling and pretty-printing awk programs
* Dynamically adding built-in functions at run time
In addition to covering the awk language, this book serves as the official "User's Guide" for the GNU implementation of awk (gawk), describing in an integrated fashion the extensions available to the System V Release 4 version of awk that are also available in gawk.
