Chapter 6. The GNU awk programming language

In this chapter we will discuss:

  • What is gawk?

  • Using gawk commands on the command line

  • How to format text with gawk

  • How gawk uses regular expressions

  • Gawk in scripts

  • Gawk and variables

NoteTo make it more fun
 

As with sed, entire books have been written about various versions of awk. This introduction is far from complete and is only intended for understanding examples in the following chapters. For more information, best start with the documentation that comes with GNU awk: "GAWK: Effective AWK Programming: A User's Guide for GNU Awk".
