Question - What is the Zombie process in UNIX? How do you find the Zombie process?
Answer -
Zombie processes are those child processes that get finished before the parent process. So after finishing up, the process structure and address space are removed and freed back to the system but the entry in the process table still exists. To be able to get the status of the child process the parent calls wait(). In the interval between the child terminating and the parent calling wait(), the child is said to be a 'zombie'.
