I tried to redirect the output, which technically is comparable with what can be seen by running "top". The result as mentioned is a somewhat locked process and its zombie child. Starting of whatever will accomplish what I am trying to do is already implemented (somewhow uglyish...;) and works...beside of the sideeffect that the program goes zombie. I definately will try the screen or tmux version (or both ;) ) ! Thank you very much for all help ! Best regards, mcc
