Description

AWK is one of the most primitive and powerful utilities which exists in all Unix and Unix-like distributions. It is used as a command-line utility when performing a basic text-processing operation, and as programming language when dealing with complex text-processing and mining tasks. With this book, you will have the required expertise to practice advanced AWK programming in real-life examples. The book starts off with an introduction to AWK essentials. You will then be introduced to regular expressions, AWK variables and constants, arrays and AWK functions and more. The book then delves deeper into more complex tasks, such as printing formatted output in AWK, control flow statements, GNU's implementation of AWK covering the advanced features of GNU AWK, such as network communication, debugging, and inter-process communication in the GAWK programming language which is not easily possible with AWK. By the end of this book, the reader will have worked on the practical implementation of text processing and pattern matching using AWK to perform routine tasks.

What you will learn

-Create and use different expressions and control flow statements in AWK

-Use Regular Expressions with AWK for effective text-processing

-Use built-in and user-defined variables to write AWK programs

-Use redirections in AWK programs and create structured reports

The awk language is a much-needed programming language for managing linux systems. The book teaches very well how to use this language correctly and effectively.

This is the AWK Book that I have been waiting to read for many years. I finally feel that I have mastered Awk Programming instead of whipping up little one liners. This will teach you many concepts about the shell as well.
