The goal of this book is to teach you what AWK is and how to use it effectively. AWK was created in 1977 as a simple programming language for writing short programs that manipulate text and numbers with equal ease. It was meant as a scripting language to complement and work well with Unix tools, following the Unix philosophy of having each program do one thing well and be composable with other programs. The computing world today is enormously different from what it was in 1977. Computers are thousands of times faster and have a million times as much memory. Software is different too, with a rich variety of programming languages and computing environments. The Internet has given us more data to process, and it comes from all over the world. We’re no longer limited to the 26 letters of English either; thanks to Unicode, computers process the languages of the world in their native character sets. Even though AWK is nearly 50 years old, and in spite of the great changes in computing, it’s still widely used, a core Unix tool that’s available on any Unix, Linux, or macOS system, and usually on Windows as well. There’s nothing to download, no libraries or packages to import — just use it. It’s an easy language to learn and you can do a lot after only a few minutes of study.
