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.

Linux was first built by Linus Torvland. He wrote it because he did not want to pay for a UNIX operating system. He then posted a message saying that he intended to make the code free ans accessible to everybody.
Yes the code is very Similar to UNIX, in fact when it was first written it was almost identical. I think there have been some legal battles over this.
However there is no UNIX code per say, in the linux operating system. Just code that has been rewritten in an identical mannor.
In general opinion diverge as for the real meaning of Linux, offical version is that it stans for Like-Unix but un-official version (supported by most of the fans ) states that it stands for a combination of Linus + Unix.
Short history: Linus wrote first version when he was dissatisfied by performance of a UNIX-Based OS for Personal Computers called Minix and he had some ideas on how to improve the operation of it. So while Linux operates (and looks) almost identical to Unix, there is no Unix code in it per-se and all the function that are similar were just written and designed to emulate how they work in Unix itself.
Not only did I read it I posted that entire line above my comment.
It is not true.
EDIT: To hopefully stop cluttering up this thread with silly bickering:
I believe the statement, "Yes the code is very Similar to UNIX, in fact when it was first written it was almost identical." to be untrue for the reason stated in my first response. Linus wrote the Linux kernel from scratch.
Then we jump to a second statement, "The commands were the same and the feel of the OS was the same." This statement is correct and not the same as the first statement.
Linux is a Unix like system. I would suggest checking the GNU site for better information about the software that gives Linux the functions most of us are used to.
I believe the link in my first post has good information regarding Unix and Linux history.
jax8, I am not going to just argue. Please post informative links or comments as you wish.

Originally posted by Ghost_runner want to really confuse things, add the word Posix into this debate
Posix is simply a standard that says that things should act a certain way. Just because both Ford and Honda autos meet US federal standards does not mean that a Ford and a Honda are the same or that they use the same parts.
I think this is a relevant link. It's back from when AdTI was trying to claim Linux was based on Minix, so it's more about Andrew Tanenbaum(author of Minix) and Ken Brown(AdTI goon). It does, however, touch on the history of the Linux code.
