Like I said, realised I had been putting "sudo" at the beginning of the line rather than after the pipe (vbar).   But thanks for replying and adding further clarity for anybody else that gets stuck at the same point.

I didn't catch that you'd updated your post until after I made mine, but as you say, it does spell it out for the next person -- I made the exact same initial error myself.
