this is a BAD posting. Stop behaving like that.
Why?
Very easy: imagine instead of Kapil a 14-year-old boy writes such a
posting. Because he's curious to learn programming. O.k., in this
case Kapil said he's been working  as a sys admin, but in other cases
you may have a question from someone who can't have the knowledge
and/or experience to know better. And postings such as yours will
surely keep this poor chap from asking again. Do you see what your
behaviour leads to? You will keep people from asking because they
don't like being offended like this.

Yes, I consider your posting offensive. You should honestly
reconsider your behaviour. Or stop answering to such questions, if
you want to behave like that. Be glad that I'm not the moderator of
this group, otherwise this post from me would be the first and last
warning: stop your mean, unkind, and discouraging behaviour, or I'll
ban you.
Now I am _not_ the moderator, so even if I wanted to, I couldn't do
that. But your behaviour is really worth some consideration. I don't
ask you to be ashamed of yourself; just think about how you want to
be treated, and then treat other people in the way you want to be
treated. I assume you prefer to be treated kindly and honestly, don't
you? So treat other people the same way, not haughty.
