Installation on Linux

All the examples in this book are covered using Linux distribution (openSUSE Leap 42.3). In order to practice examples discussed in this book, you need GNU AWK version 4.1.3 or above to be installed on your systems. Although there won't be drastic changes if you use earlier versions, we still recommend you use the same version to get along.

Generally, AWK is installed by default on most GNU/Linux distributions. Using the which command, you can check whether it is installed on your system or not. In case AWK is not installed on your system, you can do so in one of two ways:

• Using the package manager of the corresponding GNU/Linux system
• Compiling from the source code

Let's take a look at each method in detail in the following sections.
