These simple commands test send, receive, transmit, and retrieve.. First two users are logged into the system. Then the first user (john) demonstrates listproc to show the current processes and in order to read the process ID's. A message is then sent to the second user (pdenning) by using the send command. pdenning then receives the command by using the receive command. Lastly john transmits a message and actually gets it himself by using the retrieve command.
