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++

The examples in this book use a syntax compatible with BASH Shell. If you're a windows user (as I am) don't bother trying to adopt it in Command Prompt or Powershell. The syntax isn't the same. After about a week of trying to read this and find the "Command Prompt" way to do the examples, I ultimately downloaded UBUNTU for Windows which is basically BASH for Windows.
After that, the examples worked exactly as described! :)
Working in AWK is a bit like thinking in ladder logic, but using text and a funky syntax. It's hard to find a system that doesn't have AWK, and I like the natural regex syntax (I'm sick of having to escape my controls in sed.)

Mit etwas Programmiererfahrung in irgendeiner Sprache ist dieses Buch auch als Einstiegswerk in die Welt von awk geeignet. Wer es nicht ganz so genau wissen will, erhält mit dem Buch sed&awk (ebenfalls von Arnold Robbins) die Hilfe für zwei Tools zum Preis von einem.
