A shell object allows you to execute UNIX commands (on Mac OS X and Linux) or a DOS command (on Windows) and get the result back as a string.

With a shell you can execute some advanced command which are usually only accessible from a terminal window. The main drawback is that you will have to parse the result string and that such output may change with the different version of the UNIX/DOS commands.
