Book Excerpts:

If you are like many computer users, you would frequently like to make changes in various text files wherever certain patterns appear, or extract data from parts of certain lines while discarding the rest. To write a program to do this in a language such as C or Pascal is a time-consuming inconvenience that may take many lines of code. The job may be easier with awk.

The awk utility interprets a special-purpose programming language that makes it possible to handle simple data-reformatting jobs with just a few lines of code.

This book teaches you about the awk language and how you can use it effectively. You should already be familiar with basic system commands, such as cat and ls, and basic shell facilities, such as Input/Output (I/O) redirection and pipes. This book also serves as the user's guide for GNU awk (known as gawk), explaining the extensions and features that are unique to gawk. It includes a wealth of sample programs and library functions that demonstrate good awk programming style.
