I've just responded to this question, and apparently solved the (first) problem the asker encountered. The question itself hints that the asker has very little knowledge on how to use Linux, basic shell commands, directory structure, etc, and may be extremely out of his/her depth. They're following a tutorial and can't even get all the commands right!
I feel like I should flag this for closing, but similarly the question was fairly well structured: clear definition of problem, evidence of some attempts to solve the problem themselves, command output, etc. Not the worst question I've come across, certainly.
Should we flag such 'well-formed' questions as off-topic/not-professional-sysadmin-stuff? Or migrate elsewhere?
