Chapter 12. Working with common command-line applications, part 2
The previous chapter discussed a few command-line programs that are useful for keeping your system running smoothly. This chapter picks up right where chapter 11 left off, getting us into a few more programs that have systemwide implications.
The commands we’ll discuss in this chapter are powerful ones. We’re going to work with the su and sudo commands, which let you do a lot of administrative tasks on your system. We’re also going to talk about installing and removing software using commands, rather than a graphical package manager. And then we’re going to finish off the chapter by learning about pipes and how to use different commands together.
The previous two chapters have been about getting you comfortable with the command line and showing you what the command line can do. This chapter is going to prepare you to work with your system. These are commands that you need to know and understand to be an effective Linux user. For instance, you need su or sudo to do most administrative tasks on your system. But don’t let that scare you! The work of the previous two chapters has gotten you ready for this moment. Let’s get started.
