What happens to zombie processes?
Overview. When a process ends via exit, all of the memory and resources associated with it are deallocated so they can be used by other processes. However, the process’s entry in the process table remains. The parent can read the child’s exit status by executing the wait system call, whereupon the zombie is removed.

To kill a process use the kill command. Use the ps command if you need to find the PID of a process. Always try to kill a process with a simple kill command. This is the cleanest way to kill a process and has the same effect as cancelling a process.

Does child process die when parent dies?
The child process is spawned in the background. The shell waits for a newline (or an EOF) then kills the child. When the parent dies –no matter what the reason–it will close its end of the pipe. The child shell will get an EOF from the read and proceed to kill the backgrounded child process.
Which command is used to suspend a process?
You could suspend a process by using Ctrl-Z and then running a command such a kill %1 (depending on how many background processes you have running) to snuff it out.
What is zombie process daemon?
Whenever a process terminates, all of its children (running or zombie ) are adopted by the init process. Zombies are child processes which have already terminated, and exist when their parent is still alive but has not yet called wait to obtain their exit status.
