What is 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 which is causing a major evolution in the world of computers. It outperforms other operating systems on similar hardware and is available on architectures ranging from a PDA to supercomputers.

A modern operating system like Linux is even easier to install and use than Microsoft® Windows™, especially given the reboot nightmares, viruses, worms, driver-update hassles and Service Pack annoyances that come with Microsoft® Windows™.

Linux and Open Source technologies have become the standard platform of choice for IT system deployment. Over seventy percent of the internet is running on Open Source technologies and international vendors such as Sun, Novell and IBM are deploying Linux and Open Source.

If you don't have a dedicated Linux box, you can use a Live Linux CD-ROM-based distribution such as Knoppix . Knoppix will let you run Linux directly from the CD without modifying anything on your hard drive.

Learning Linux Commands

If you are a complete newbie to Linux, or if you “know enough to be dangerous,” then here are some pointers that may help.

One of the great things about Linux is that, even though the operating system is extensible through the addition of arbitrary commands, there are standards for documenting such commands. Because of these standards, not only is it easy to find out what a command does and how it works, but it’s easy to find out that these commands exist in the first place, even if you don’t know their names.
