Appendix A: Glossary of Linux Terms


This appendix provides brief explanations of common terms used in the Linux and Unix world. These include technical terms, as well as conventions used within the Linux community. Due to space limitations, this glossary is somewhat selective, but still should prove a lasting reference as well as a helpful guide for those new to Linux.

Cross-referenced terms are highlighted in italics.
