An Introduction to Linux (For Beginners)
Now before we proceed to Backtrack we should have some Basic Idea of what is Backtrack. Well So First We Cover about Linux, which is pretty much the same as backtrack. If you can get hold of Linux, Backtrack is your Best Friend. Well I have tried to cover Backtrack 4 (ONLY). Didn’t Use Backtrack 5 or Higher versions although I haddownloaded and kept. But in a recent HDD crash I lost all the dat a. Sometimes Later We Will cover Backtrack Higher Versions.

1. What is Linux? Linux is a free Unix-type operating system for computer devices. The operating system is what makes the hardware work together with the software. The OS is the interface that allows you to do the things you want with yourcomputer. Linux is freely available to everyone. OS X and Windows are other widely used OS.

Linux gives you a graphical interface that makes it easy to use your computer, yet it still allows those with know-how to change settings by adjusting 0 to 1.

It is only the kernel that is named Linux, the rest of the OS are GNU tools. A package with the kernel and the needed tools make up a Linuxdistribution. Mandrake , SUSE Linux, Gentoo and Redhat are some of the many variants. GNU/Linux OS can be used on a large number of boxes, including i386+ , Alpha, PowerPC and Sparc. 2. Understanding files and folders Linux is made with one thought in mind: Everything is a file. A blank piece of paper is called a file in the world of computers. You can use this piece of paper to write a text or make adrawing. Your text or drawing is called information. A computer file is another way of storing your information. If you make many drawings then you will eventually want to sort them in different piles or make some other system that allows you to easily locate a given drawing. Computers use folders to sort your files in a hieratic system. A file is an element of data storage in a file system. Filesare usually stored on harddrives, cdroms and other media, but may also be information stored in RAM or links to devices. To organize our files into a system we use folders. The lowest possible folder is root / where you will find the user homes called /home/. / /home/ /home/mom/ /home/dad/ Behind every configurable option there is a simple human-readable text file you can hand-edit to suit yourneeds. These days most programs come with nice GUI (graphical user interface) like Mandrakes Control Center and Suses YAST that can smoothly guide you through most configuration. Those who choose can gain full control of their system by manually adjusting the configuration files from foo=yes to foo=no in an editor. Almost everything you do on a computer involves one or more files stored locally or ona network. Your filesystems lowest folder root / contains the following folders: /binEssential user command binaries (for use by all users)/bootStatic files of the boot loader, only used at system startup/devDevice files, links to your hardware devices like /dev/sound, /dev/input/js0 (joystick)/etcHost-specific system configuration/homeUser home directories. This is where you save your personal...
