Linux: Introduction to Linux
Linux is a free Unix-type operating system originally created by Linus Torvalds with the assistance of developers around the world. Developed under the GNU General Public License, the source code for Linux is freely available to everyone. In this tutorial, Arthur Griffith explains and demonstrates everything you need to know to begin understanding and using Linux. From history to philosophy, installation to networking (even Cygwin X Server and RedHat); whether you have a passing interest in a new OS, or would like to become a Linux engineer, the VTC 'Linux: Introduction to Linux' tutorial is the best place to start.
