Comment(by raimue@…):

 `exit` is a valid command in the interactive port shell. There is no
 distinction between commands at the moment and all of them can be called
 in both interactive mode and from command line.

 Commands that do not need to be available on the command line interface:
   * cd
   * quit
   * exit
