you don't create zombie processes. zombie is a process state. the process does not actually exist. Read up on what a zombie process is and then you will understand how to do it. I don't understand why a UNIX newbie would be trying to do this though.
A ZOMBIE program is NOT something you want in your system.
It is a process that crashed and which is robbing memory space and/or cpu cycles.
They are detached from any terminals or processes that lauched it in the first place and are hard to kill. sometime only a reboot can get rid of it.
However, if you want to launch a program in the background there is 2 options to do so.
A) /usr/bin/your program & B) nohup /usr/bin/your program
The differences lies in what your program do when you log out.
A) The program terminates upon login out
B) The program keep on running and only a kill or fuser command will stop it.

this is an incorrect statement. a zombie process is not taking up system resources. the process does not actually exist anymore. the entry is left in the process table until the parent reads its exit status. The only resource used is the slot in the process table.
