About the Book
The book heavily leans on examples to present features of grep as well as regular expressions one by one. It is recommended that you manually type each example and experiment with them. Understanding both the nature of sample input string and the output produced is essential.
You should have prior experience working with command line and bash shell, should know concepts like file redirection, command pipeline and so on.
Exercises are also included to test your understanding.
