Newby question: The command "script" cannot be found

Hi

I have just installed Ruby on rails and I´m trying to run the following
starting example:
http://rfacebook.wordpress.com/2007/12/28/quickstart/

The console does not recognize the command script:

c:\ruby\myapp>script/plugin
Der Befehl "script" ist entweder falsch geschrieben oder
konnte nicht gefunden werden.

What have I missed out? Any help is appreciated.

Thank you
Tobias
