Silly Linux
cp is used to copy files so I try rn. No luck. So I think perhaps they are being nice so I try rename. This seems to work. But the file is not actually renamed. When I type the command on its on it says call: rename from to files. Nice but not useful. After a quick search I find out how to do it: you need the move command. Well to be precise the mv command. After a moment's thought it does make sense but it is not intuitive...
