This is all very good Jeff, but how do to get into the Shell?  A HELP SHELL or
HELP POSIX told us nothing. The manual "Using the Hierarchical File System"
mentioned the HPPXUDC catalog file with the sh udc invoking the posix shell to
give us a $ prompt. This is where we hit the "wall". Any of the commands in your
examples (rm, mv, find, cat) return "not found". Where do we go from here?
