Ubuntu comes with a great graphical user interface (see Chapter 6, "The X Window System") that gives you an easy way to administer and maintain your system. However, you may not always have the luxury of a window manager, especially when things go wrong. In this chapter we will take a look at some of the basic command line functions that may come in handy should you need to use them. For more advanced functions you should look at Chapter 33, "Command Line Masterclass."
Some of the basic command-line skills covered in this chapter include
• Performing routine tasks Logging in and out, using the text console, changing passwords, listing and navigating directories
• Basic file management Creating, renaming, or deleting files and directories
• Basic user management Creating or deleting users from the command line
• Basic system management Shutting down or rebooting, reading man pages or other documentation, and using text-based tools to edit system configuration files
This chapter is essential reading if you are totally new to Linux; it will help you make the jump from other operating systems and give you a good grounding in entering commands at the command-line.
