Hello Fingers99 and Freitag. Many thanks for coming in to help me. Yes, I did type it all in because thats what I was told to type in. This is from the book 'Knoppix Hacks' by Kyle Rankin. But having had a second look at the book in question, I can see that sudo knoppix-installer is actually in bolder type than the rest. If the author had written type in the command in bold, then I would have done so. But there you are, thats me all over.

Oh boy, I can see that there will be some stormy seas ahead and I shall have to be extra careful of what I type in in future. Thanks again for being so kind and for the help given. Regards Grandad.
