System administration is generally a skill with which even casual Linux users must become familiar, simply in the course of day-to-day work. In this chapter, you learn how to perform a number of basic system administration tasks using command-line tools.

Because the tools in this chapter are all carried out at the command linewhether at the console, in a terminal window, or through a remote loginthere aren't any figures. However, the examples illustrate the steps involved in each type of task.
