There, the intention was to have an "operator" shell that would run certain commands a ROOT (like PS, SHUTDOWN, etc), and the rest as a normal user ("operator"). The set of commands which would run privleged was carefully selected to prevent operators from gaining undue control over the machine, yet still be able to take backups, etc. The version which is presently running at JHU is based on the old V6 shell, but the concepts employed in the code might very well be moveable into newer shells. Contact Bob Miles or Bob Jesse for details. -Mike
