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.

Originally posted by david_ross To start with you wanted version numbers so that's what I suggested. If you want a date then try escaping the date command with whatever format you want - eg:
I tired using `date` inside sed command but its not working ....
sed 's/oldfile/newfile.v`date`/' oldfilename >newfilename
in the results I am getting expression: newfile.v`date`......rather
then newfile.v FEb 9............
For what it's worth, the tool that I vastly prefer to use for most such things is awk, not sed.
Although sed is clearly a powerful piece of software, I find that it suffers greatly from chicken-scratch-itis which means that, even for my own code, I find myself staring at a line full of punctuation-marks ("chicken scratches") puzzling what they mean.
