Which UNIX? There are different courses for AIX, HP-UX, Solaris, and Linux (that I know of). Most are geared towards intermediate users who already know their way around the command line.
The Oracle DBA courses (at least those that I attended) require you to know the command line, and the basic structure of UNIX-like OS' pretty well, especially the parts about disaster recovery.
