Overview of this book

In Linux, one of the most commonly used and most powerful tools is the Bash shell. With its collection of engaging recipes, Bash Cookbook takes you through a series of exercises designed to teach you how to effectively use the Bash shell in order to create and execute your own scripts. The book starts by introducing you to the basics of using the Bash shell, also teaching you the fundamentals of generating any input from a command. With the help of a number of exercises, you will get to grips with the automation of daily tasks for sysadmins and power users. Once you have a hands-on understanding of the subject, you will move on to exploring more advanced projects that can solve real-world problems comprehensively on a Linux system. In addition to this, you will discover projects such as creating an application with a menu, beginning scripts on startup, parsing and displaying human-readable information, and executing remote commands with authentication using self-generated Secure Shell (SSH) keys. By the end of this book, you will have gained significant experience of solving real-world problems, from automating routine tasks to managing your systems and creating your own scripts.

For example, Bob the reader has already been introduced to VI, and perhaps he has his own GUI editor or application, such as Open Office, but what happens if that editor likes to crash upon opening a full file? Can he just look at the starting few lines? Absolutely. Can he split that file (if the structure is known like a CSV) at X number of lines? Again, absolutely!

All of these things are not impossible, and the list of activities Bob can do can continue on forever. The idea of this chapter is to give you a segue into some of the things you can do if...
