Answer 1

Apology accepted.
But yes, of course I was harsh (not at you, actually, but at the plonker who thinks he can tell me that 'echo $something' is "not right").
Do you know how many questions could be answered here if people weren't forever debating perfectly acceptable answers? If people actually stopped to read what had been written before deciding to add their tuppence-worth? If people stopped to think, "well, that's not how I would answer it... but it's good enough".
I see so many threads here where 58 people dive in to a thread to say, 'Me too'. Another 42 will dive in to say, 'that's not right' when actually it is. And another 137 or so will usually chime in to say nothing very much except to demonstrate that they didn't understand something that was explained a lot earlier on quite clearly. Threads go on and on, when actually all that was sought originally was a simple answer to a technical issue. God knows why it happens.
I have no problem at all being asked for clarification. I have no problem at all being corrected and having someone point out that actually that parameter doesn't exist, you made a typo, that's not the command to achieve X. When I am technically wrong, I would expect nothing less. But where so much of my time gets wasted is demonstrated in this thread perfectly. I answered the question in one post. It might not have been a perfect answer. There are many different ways of coming up with the answer on Windows, for example, and yet I didn't mention the registry at all or the Control Panel/System applet for checking environment variables once. And yet, despite all of that, in answer 1 there was sufficient information to make the OP happy. But no, that's not enough to shut some people up (and I am again not referring to you at this point).
I don't know what it is. Some sense of, maybe, in a democracy my opinion is as good as yours even if it's entirely unnecessary, potentially confusing and adds absolutely nothing to the outcome? A desire on the part of some people to boost their post numbers?
Too right I'm harsh. I am results-driven. I am here because I want to help others. Not because I think my opinions deserve a hearing even though the answer was posted ages ago. When I see something that looks like the opposite of that -grandstanding, look how clever I am, my opinion counts too- yeah, it annoys me somewhat. And largely because I usually end up having to untangle the confusion caused by unnecessary "contributions" from others.
