When processing text files, the awk language is ideal for handling data extraction, reporting, and data-reformatting jobs. This practical guide serves as both a reference and tutorial for POSIX-standard awk and for the GNU implementation, called gawk. This book is useful for novices and awk experts alike.

In this thoroughly revised edition, author and gawk lead developer Arnold Robbins describes the awk language and gawk program in detail, shows you how to use awk and gawk for problem solving, and then dives into specific features of gawk. System administrators, programmers, webmasters, and other power users will find everything they need to know about awk and gawk. You will learn how to:

Format text and use regular expressions in awk and gawk

Process data using awk's operators and built-in functions

Manage data relationships using associative arrays

Define your own functions

"Think in awk" with two full chapters of sample functions and programs

Take advantage of gawk's many advanced features

Debug awk programs with the gawk built-in debugger

Extend gawk by writing new functions in C or C++
