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.

Is this possible using some simple command in Linux? Or will I need to use awk (or maybe sed) in a loop to accomplish this?
Problem with using the above two commands (sed/awk) in a loop is that I fear that might not be optimal as far as performance of code is concerned as the files I am working with are huge (millions of records each).
