Hi Rozel, earlier you said: Which is what lead me to assume you already had the alias working correctly. Perhaps this was a typo, and you meant to say that you'd typed "iplayer-dl URL"? I suggest you never ever enter the command "iplayer-dl URL" unless you've read all of the posts in this thread and understand what that will do (and why it's a bad idea). Alternatively perhaps you removed your .profile file (which I didn't say to do, but it's no problem). Either way you should be able to just enter the echo command in a new terminal, but DO NOT type "sudo gainroot" first. This needs to be done as the normal user, not the root user. There is no "usual" sudo gainroot command, you should only ever type this when explicitly told to, or difficulties are inevitable. You're nearly there! Jan
