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.

I would like to learn HP unix and i know we cann't install hp unix in pc.
Is there any alternative Operating System which has similar environment like hp unix that can be installed in a pc or laptop..
I heard Open BSD is having some features like HP Unix, what's your comment about that?
Any reply will be greatly helpful.
Thanks & warm Regards..
Except that they are both "UNIX" rather than "Linux" BSD isn't very much like HP-UX.
For most day to day purposes knowing one flavor of UNIX or Linux is very helpful on most other flavors. However, there are differences in options for the same command name on different UNIX and Linux OSes.
The main differences in UNIX variants and Linux distros are in administrative tools. For example HP-UX using SD (swinstall etc...) for installing new packages whereas Solaris uses a different tool, RedHat, Fedora and CentOS Linux use rpm and yum whereas Debian, Ubuntu and others use apt and BSD does it differently than all of those. Similarly network configuration is different. HP-UX has an admin tool called SAM whereas AIX uses SMIT or SMITTY, Solaris uses multiple tools and Linux variants use different tools.
On the flip side HP-UX has native support for LVM which is now available in Linux and the implementation on the two is very similar using mostly the same commands.
If your idea is to get experience as an HP-UX admin there really isn't going to be much substitute for using a live HP-UX system. There are resellers of refurbished equipment but even then it isn't cheap as compared to PCs.
As mentioned, for anything other than 'UNIX Fundamentals' you do need the exact system in question.
However for learning those fundamentals, my opinion is that Linux is a fine choice. Browsing through the Debian repositories, there are a lot of different shells available so you should be able to get a pretty similar environment for doing practical examples.
Have you looked at the link from chrism01? There's a lot of HP-UX-specific documentation on there, free for the downloading. Good stuff there.
Beyond that, I agree with the majority here--it's best to make an investment in your future career by purchasing an older system on eBay and actually run the operating system yourself. Given the differences between comomercial Unixes, experience really is the best teacher.
