Hi @jacques.florin,

I couldn’t really understand what you mean.

Could you tell us exactly:

  1. What you are trying to do
  2. Which commands you have tried
  3. The expected output
  4. The result you have got

The more details you provide, the better it is for us to help you.

Try to be as clear as possible so that we can better help.

Chers.
