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.

About 2 years ago I installed Red Hat 7.3 just before I signed up for a 2 credit Unix course at a University. As I was doing my homework at home I would try out the "Unix" commands on my Linux box. Then I would later try using the commands on one of the Unix computers at the University. Nearly every command we learned about worked the same under both Unix and Linux.
I suspect that many details of configuring the systems might be different however we did not cover much of that in the course. The activities that we did which were more or less identical included:
1) Accessing one Unix computer from other using commands such as SSH, telnet, rlogin. Then running programs remotely from the other computer.
2) Writing programs in C or C++ using the g++ compiler and/or the ddd debuger.
3) Using text editiors such as vi, vim or emacs
4) Setting permissions on files and folders using chmod
5) Transfering files between ftp servers with the ftp command
6) Using common ordinary commands such as ls, cat, mkdir, rmdir, cp, finger, whoami, find, grep, fgrep, egrep who, awk, mount and tar
7) Copying and pasting text using the middle mouse button.
So learning to use Linux is a way to learn about Unix! You can also learn about Unix by installing the free Cygwin Unix emulator to be run under Windows.
