Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

First of all, please spell out your words, text speak is not appreciated on LQ forums. Besides that this sound a lot like homework and although it's not against the LQ Rules to ask for help with homework, you shouldn't post it verbatim nor should you expect us to do the work for you. We'll be glad to point you in the right direction if you show us what you've already figured out and where it's failing. And as a last point, don't ask for privileged attention, it's only urgent to you, not to us who are all volunteers here.
A good starting point is Google and the man page for grep
Looking forward to your participation in the forums. Have fun with Linux.
