Execute basic system management-Shutting down or rebooting, using text-based tools to edit system configuration files, and reading man pages, which are entries for commands included as files already on your computer in a standardized manual format.

Implement basic file management-Creating files and folders, copying or moving them around the file system, renaming and deleting them.

Perform routine tasks-Logging in and out, changing passwords, listing and navigating file directories.

This chapter introduces you to commands that enable you to do the following: More importantly, though, you will be able to make your way around a command lineвЂ“based system, which you are likely to encounter if you ever work with a Linux server since many Linux servers have no GUI and all administration is done using a command line interface via SSH. However, with a little perseverance, by the end of this chapter you will start to feel comfortable using the command line and you'll be ready to move on to Chapter 35, 'Command Line Masterclass.' Initially, some may be tempted to think of the command line as the product of some sort of black and arcane art, and in some ways it can appear to be extremely difficult and complicated to use.

Doing so will benefit you greatly for years to come.

You should take the time to work through the chapter and ensure that you are comfortable with the command line before moving on. Also, some tasks end up being far easier and faster to accomplish from the command line.Дon't be tempted to skip over this chapter as irrelevant. In these situations, a fundamental understanding of the command line and its uses can be a real lifesaver. Sometimes things go wrong, and you may not have the luxury of a graphical interface to work with. There are some good reasons to acquire a fundamental level of comfort with the command line that you should consider before embracing that view. Some may say that you will never need to access the command line because Ubuntu offers a slew of graphical tools that enable you to configure most things on your system. You may develop an affinity for the command line when performing some tasks and prefer the GUI for others. It is not necessary for you to embrace either extreme. Others will either praise its power or comment about doing something via the command line as if it is the most natural and obvious way to complete a task. Some, especially those who have begun their journey in the Linux world using distributions, like Ubuntu, that make it easy to complete many tasks using a graphical user interface (GUI), may speak with trepidation about the mysteries of the text interface. If you spend any amount of time with experienced Linux users, you will hear them mention the command line. The skills you learn in this chapter will help you get started using the command line with confidence.

Later in the book we present a Command Line Masterclass (Chapter 30), which explores the subject in greater depth.

You will find out how to get to the command line, and learn some of the commands used to navigate the file system. If you are interested, you can learn more about the GNU Project at This chapter looks at some of the basic commands that you need to know to be productive at the command line.

Many of the commands were created by the GNU Project as free software analogs to previously existing proprietary UNIX commands. Knowledge of the commands available to you and also how to string them together will make using Ubuntu even easier for many tasks. It is an efficient way to perform complex tasks accurately and much more easily than it would seem at a first glance. The Linux command line, sometimes called the terminal, is one of the most powerful tools available for computer system administration and maintenance.
