A very handy reference, February 7, 2009
This review is from: Grep Pocket Reference (Pocket Reference (O'Reilly)) (Paperback)
This little book is everything a pocket reference should be. grep and egrep are not hard to use, but there are quite a few valid combinations of options, and this book pretty much covers them all. If you want to find expressions in one or more files, this is the tool to use. It's easy to forget everything available, so this book puts everything in one place for you. There's even a section on an option of grep that is only valid with PERL, so you may or may not have access to it. The following is the table of contents since it is not listed in the product description. One word of warning - if you don't already understand regular expressions this book won't teach it to you. It is indeed just a quick reference for concepts you should already know. The advanced tips and tricks section is the only exception to that rule and is itself worth the price of admission.

Command man grep and beyond..., November 23, 2010
This review is from: Grep Pocket Reference (Pocket Reference (O'Reilly)) (Paperback)
It has beyond what you will learn from Man pages of grep. Few examples will surely make you understand the power of grep command.

Outrageously Useful! AAAAAA+++++++, January 21, 2011
This review is from: Grep Pocket Reference (Pocket Reference (O'Reilly)) (Paperback)
As a lifelong bibliophile, I can honestly say that few books come even remotely close to this one for usability and functionality.
i.e. for years I had thought that \r was just an acronym for \n, but this book disabused me of this, and much other nonsense.
There aren't enough superlatives in the dictionary!
I could not, very easily, live without it.
