This document aims to briefly outline the differences and similarities between UNIX and DOS (MS-DOS, DR-DOS etc.). This is so that newcomers to UNIX can get started quicker if they already know a little about DOS.
For more information on specific commands, consult the UNIX on-line manual pages. For further information about UNIX in general, read UNIXhelp for Users.
