Читать книгу Linux Command Line and Shell Scripting Bible - Christine Bresnahan - Страница 5

This chapter discussed the Linux system and the basics of how it works. The Linux kernel is the core of the system, controlling how memory, programs, and hardware all interact with one another. The GNU utilities are also an important piece in the Linux system. The Linux shell, which is the main focus of this book, is part of the GNU core utilities. The chapter also discussed the final piece of a Linux system, the Linux desktop environment. Things have changed over the years, and Linux now supports several graphical desktop environments.

The chapter also discussed the various Linux distributions. A Linux distribution bundles the various parts of a Linux system into a simple package that you can easily install on your PC. The Linux distribution world consists of full-blown Linux distributions that include just about every application imaginable, as well as specialized Linux distributions that include applications focused only on a special function. The Linux LiveCD craze has created another group of Linux distributions that allow you to easily test-drive Linux without even having to install it on your hard drive.

In the next chapter, you look at what you need to start your command line and shell scripting experience. You'll see what you need to do to get to the Linux shell utility from your fancy graphical desktop environment. These days, that's not always an easy thing.
