Thank you Can anyone recommend a good book to get learn these command line codes. I am new to linux and am tired of chasing Blue Rhinos around discussion boards.

Or this one:

Ouch! Heavy editing of this post needed!

The Linux Cookbook (http://dsl.org/cookbook/)
is available online for free!

The O'Reilly books are excellent, but if you just need a quick and simple introduction to the commands try a some of these:

If you do a search on Google you'll find a lot more, as a lot of the LUGs have beginners' guides and university lecturers usually include this kind of stuff in their online notes

Linux for Windows Addicts (Miller)

Linux System Administration (Stanfield, Smith)

Real World Linux Security (Toxen)

Get this book:

Red Hat Linux Networking and System Administration
by Terry Collins & Kurt Wall


I know it sounds daunting, but it explains everything in plain english. Step by step from installing Red Hat Linux 7.2, to mail, webserver, ftp, etc. -- and the last couple chapters are on security.

Go to Amazon and read the reviews on it. Then go to a bookstore and browse it.

You won't have to buy another book to understand this book.
