Читать книгу Linux Bible - Christopher Negus - Страница 46

Linux is an operating system that is built by a community of software developers around the world, which is led by its creator, Linus Torvalds. It is derived originally from the UNIX operating system but has grown beyond UNIX in popularity and power over the years.

The history of the Linux operating system can be tracked from early UNIX systems that were distributed free to colleges and improved upon by initiatives such as the Berkeley Software Distribution (BSD). The Free Software Foundation helped make many of the components needed to create a fully free UNIX-like operating system. The Linux kernel itself was the last major component needed to complete the job.

Most Linux software projects are protected by one of a set of licenses that fall under the Open Source Initiative umbrella. The most prominent of these is the GNU Public License (GPL). Standards such as the Linux Standard Base and world-class Linux organizations and companies (such as Canonical Ltd. and Red Hat, Inc.) make it possible for Linux to continue to be a stable, productive operating system into the future.

Learning the basics of how to use and administer a Linux system will serve you well in any aspect of working with Linux. The remaining chapters provide a series of exercises with which you can test your understanding. That's why, for the rest of the book, you will learn best with a Linux system in front of you so that you can work through the examples in each chapter and complete the exercises successfully.

The next chapter explains how to get started with Linux by describing how to get and use a Linux desktop system.
