These commands are a strict minimum to survive in VisLab.
If you want to know more about UNIX,
there is a manual somewhere in VisLab which gives a basic
introduction to UNIX (you might have to do some research!).
Finally, if you have any problems (computer-related only!),
shout HELP!!! and rescue should be under way within minutes
in the person of Ben, Chris, Mitch. Wei or Nicole (don't ask Bernard!).
