As the initial 4 sessions remain quite basic, for those already familiar with the Operating System, only the Shells and Scripting Lectures, or just the last one would be worth attending, unless a refresher is wanted anyway. Each session after the first begins with a quick recap, so those missing any session can still join or continue with the course and are welcome to do so.

The course may be complemented by basic Fortran and 'C' Programming courses, each also of 6 one hour lectures, intended for beginners in those languages. These are normally advertised separately.
