Red Hat Linux includes the Linux kernel and a large collection of utilities and applications that make it a complete operating system. Most of these utilities and applications are from the GNU Project. In a way, Linux has become a full-fledged UNIX-like operating system primarily because of the GNU software. The GNU Project provided everything from the software development tools—assembler, compiler, and make—to GNOME, the graphical user interface (GUI) desktop. This chapter gives you an overview of the GNU software and introduces you to some of the GNU utilities.
