ABSTRACT
If you are serious about computing, safeguarding security, and understanding how an operating system works, Linux is the system of choice. To learn Linux you must use it, and, of course, to use it you must learn it. Such a paradox is rather common—you probably learned to drive a car this way. You just need some basic help and pointers to get started. Here we present an overview of basics. Once you understand the material in this chapter, you will be able to use the operating system to learn more in each successive chapter. At first, you need a learner’s permit to drive a car. Consider this chapter your learner’s permit for Linux; with a little practice you will be using Linux almost right away.
