George is getting brave again. He has heard about a CentOS command called grep and he thinks he can use this to work with his files. He wants you to write up a document explains how to use the grep command. He wants to be able to search for files by name, search for files with specific contents, to ignore the case of the text when searching for text, and count the number of times a string occurs in his files.

Write a short User Guide for George that will explain how he can do the things he wants to do with the grep command. Take screen shots to show the commands you are using in grep. Write your instructions like you were writing them for a business user, using correct grammar, spelling, punctuation, and capitalization.
