grep Pocket Reference

tells you what you need to know. I keep it close to hand as grep is so powerful that you only use a few % of its capabilities and unless you use it frequently (I don't) you won't remember everything you looked up how to do.

I expected the reference to be a bit thicker but after flipping through the pages I realized that it covered almost all useful scenarios and commands.Overall a great, pocket-sized reference book riddled with useful tips and tricks and pattern examples.

One and only book on grep. If one go through it thoroughly the he will be master over grep. And last but not the least, the price is too much lower than US price.

I has eveything what a pocket book is supposed to have. A goodove rview of the great grep program although if you like a look of samples/tricks probably you need to look for another one

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.Chapter 1. grep Pocket ReferenceSection 1.1. IntroductionSection 1.2.
