Thanks for your help. I am having problem getting actual PID of process. Your open command returns the PID which is less than 1 of actual PID. for ex. PID of my actual process is 1923, i get 1922 which i discovered to be a zombie process. Can you please tell me what should i do to get the actual process id ? thanks in advance.
