Typing "help" will result in the following output. The available commands are help, cls and login, described below:
Available commands:
help - Displays this help message.
cls - Reset Terminal screen.
login [username] – logs in as the specified username to establish the
user that programs will be run as. Use 'system' or 'console' as username to
adopt the System account identity (if you have permissions), or the console
user identity (if there is a console user). Enter login with no username to
see these choices.
All other command lines are assumed to be the name of an executable file
(either on the system PATH, or with an explicit path specified) and the
remainder of the line are the arguments for the program.
