You might be already aware of popular coreutils commands like head, tail, tr, sort, etc. This book will teach you more than twenty of such specialized text processing tools provided by the GNU coreutils package.

I've been using Linux since 2007, but it took me ten more years to really explore coreutils for my Command Line Text Processing repository.

Any beginner learning Linux command line tools would come across cat within the first week. Sooner or later, they'll come to know popular text processing tools like grep, head, tail, tr, sort, etc. If you were like me, you'd come across sed and awk, shudder at their complexity and prefer to use a scripting language like Perl and text editors like Vim instead (don't worry, I've already corrected that mistake).

Knowing power tools like grep, sed and awk can help solve most of your text processing needs. So, why would you want to learn text processing tools from the coreutils package? The biggest motivation would be faster execution since these tools are optimized for the use cases they solve. And there's always the advantage of not having to write code (and test that solution) if there's an existing tool to solve the problem.

This book will teach you more than twenty of such specialized text processing tools provided by the GNU coreutils package. Plenty of examples are provided to make it easier to understand a particular tool and its various features.

Prerequisites: Prior experience working with command line and bash shell, should know concepts like file redirection, command pipeline and so on.
