Anyone who has accessed either the DOS prompt of a DOS or Windows system, or the shell capabilities of Macintosh OS X has, in fact, already worked at the command-line level. Although graphical interfaces have been displacing command-line interfaces for programming environments, we are among those who still find that the command-line interface introduces less confusion and reveals more details when one is learning about a new architecture.

In order to gain the most benefit from this book, you need to have basic familiarity with Hewlett-Packard's Unix (HP-UX) or a Linux command-line environment. In this appendix, we provide a general overview of these command-line programming environments.
