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++
