One way or another you are sitting in front of a computer that is running Ubuntu Linux. After describing root privileges, this chapter takes you on a tour of the system to give you some ideas about what you can do with it. The tour does not go into depth about choices, options, menus, and so on; that is left for you to experiment with and to explore in greater detail in Chapter 8 and throughout later chapters. Instead, this chapter presents a cook’s tour of the Linux kitchen: As you read it, you will have a chance to sample the dishes that you will enjoy more fully as you read the rest of this book.
Following the tour are sections that describe where to find Linux documentation (page 124) and offer more about logging in on the system, including information about passwords (page 132). The chapter concludes with a more advanced, optional section about working with Linux windows (page 139).
Be sure to read the warning about the dangers of misusing the powers of root (sudo) in the next section. Heed that warning, but feel free to experiment with the system: Give commands, create files, click objects, choose items from menus, follow the examples in this book, and have fun.
