I've moved this thread to our complaints department, and given it a snazzy new title. I think our client liaison is back from Mauritius in August.
Look, we're looking forward to you learning Unix too. But you have to demonstrate some willingness to learn for yourself. I most certainly did not call you "nonsense". What is nonsense is the notion that you should expect a ready-made answer to your question without you ever having made, or shown, any willingness to try to solve the problem yourself.
I appreciate that English may not be your first language, but you seemed to understand it well when you asked the question, and when you said "please provide the code".
On the other hand, were someone to answer your thread with a well-documented solution that would improve your understanding, as well as offer a solution, that would be most appreciated. In that hope, I've re-opened
your other thread.
