Be warned this book is not for those that are on something something for dummiies series. Neither is it for advanced users. It's more for us whose day job entitles going throough thousands of rows of string looking for that one line or two. Data like logs but not restricted too. It is also good as a lookup as it comes in a handy portable wallet size. I liked it and learned alot.

It's not good enough to where it'd be more efficient than Googling the solution to what I need. If you're looking for some good examples or a cookbook (a total of 9 "recipes" across 5 pages) that makes you feel like you have more in your grep toolkit, you probably won't find it here.

It does make for a good refresher if you're already very proficient in grep, in case you've forgotten a few things along the way.

HALL OF FAMEon February 7, 2009
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.

Section 1.1. Introduction
Section 1.2. Conceptual Overview

Mainly explained GNU version of GREP, which is most common version.
This pocket provides some example and explanation.
With this reference, I'm much more familiar with grep.
Grep also became one of my powerful tools.

I know it is a pocket guide, but could be a little more clear. I received the product on time and in great condition.

This book does a great job of introducing people to Regex while using the different types of grep. I have booth the paper and kindle versions. The kindle version is easier to find things in, because if search in book.

A quick reference to how to form 'grep' searches for files and file contents within the computer. I need this book to remind me about how to form the search command line.
