Because some of you have such detailed ideas how to help OPs (and especially how not) and some of you like to express this by waves of downvotes (even if th OP accepted the answer) I want to ask you for the (your) right way to do things:
Often it is necessary to get much more information from the OP and, thats the key, it is also necessary to guide she/he to collect such information. Therefore it used to be required to ask the OP to execute commands and to post the result, to ask to execute another command and to get the result and so on. Guiding to run commands using comments is often not clearly for the OP and to get the result that way may also not.
Here is an example of such a situation.
So what is the better & desired way while omit useing answers?
And, interesting too, what should be the follow up, if the answer / solution was found in the melee of the comments? Should somebody extract an answer of them an create an answer? Or should other user which the same question being dept to read all the comments to extract the answer her/himself?
