CHAPTER ONE: INTRODUCTION
Introduction
If you want to learn how to use the Linux operating system, but felt it was too complicated, this book is for you. I'm confident that as you read this book and practice the exercises that you will be able to develop a working knowledge of the Linux command line.
Once you develop a working knowledge of the command line, you will be able to tackle more advanced Linux projects with confidence. Maybe you've wanted to program your own server system, adapt a Linux system for home use, or just dabble in computer programming. Whatever the reason, you're likely to find this book helpful for your situation.
How This Book is Organized
You do not necessarily need to read this book cover-to-cover if you already understand some of the concepts. Below is a brief list of the chapters covered, along with their contents:
Linux Overview
This chapter gives a brief overview of the Linux operating system, how it was invented, what exactly open-source software means for you (the end-user), and various types of Linux and how they may differ from each other.
Linux Shells
The shell provides one way for you to communicate with your machine via a GUI or LUI interface. If you aren't familiar with these terms or want a quick refresher, read this chapter.
Basic File Directory
This chapter covers the names of basic files found in Linux, such as bin and root, and what they do.
The Linux Command Line--The Basics
If you believe you are ready to just jump in and start learning Linux commands without any preliminary information, you may skip the other chapters and start here. This chapter covers some basic Linux commands, including cd and pwd. This chapter also covers basic syntax, which will allow your commands to read correctly.
The Linux Command Line--More Advanced Commands
This chapter contains more advanced commands, such as ping, tar, and locate.
Linux System and User Management
Learn how Linux manages users and protects its important files by only granting administrator access to users with the proper permissions.
Understanding Linux Security
Even though it's open-source, Linux is one of the most secure operating systems available. Learn why and how to keep it that way in this chapter.
Suggestions for Continued Learning
Once you've gotten the basics down, maybe you would like some suggestions on what to learn next. This chapter will give you ideas on how you can continue learning about Linux.
IMPORTANT : Certain chapters in this book contain a lot of dense information. It is highly recommended that you read these chapters with a pen and paper in hand and also have access to a computer where you can practice and get comfortable with the commands. The purpose of this book is to help you get comfortable with the Linux command line so you can more confidently use Linux's most powerful features. It is not a casual read, but rather, a beginner's instruction to the basics of the Linux command line.
