I guessed as much, just me beeing a linux n00b. Thanks and sorry for wasting your time. Still, this could have been prevented with clearer instructions. It went fine with installing the software though, nice and easy to copy the commands, all clear there. Just small things like this one that you who know command line better maybe don’t realize that others don’t get.. Thanks again.
