Course notes for Unix and C are on a moon in directory:
/usr/courses/cps393/dwoit/courseNotes/

Unix notes in files: u?.txt
C notes in files: c?.txt

Sometimes I update notes, so if you make a copy of them, it is
a good idea to check for differences in your copy and this copy
periodically (you can use the Unix diff command).

These notes are for cps393 students only. Anyone not a CPS393
student has no permission to do anything to/with these notes.
They cannot be copied, viewed, etc.

As a cps393 student you have permission to copy the notes and use 
them yourself, but you do not have permission to make them publicly 
available, nor available to anyone outside of class.
Once you are no longer  a CPS393 student, you may retain a copy for 
your personal use only and may not make them available to anyone 
else (including publicly available).
