I just wanted to mention this free pdf file.
If you are a linux admin or someone who wants to learn shell scripting and
regular expression check this book. The book has a lot of exercises
This book made me understand a lot of concepts that i had a hard time understanding in the past

with the help of this book and bashscripts.org I think we all can become decent shell script programmers and come up with
some nifty shell scripts to make our lives easier
