The -l option to ps adds information about which processes started each process (useful when you want to identify child processes):

$ ps -l

F UID PID PPID PRI NI SIZE RSS WCHAN STAT TTY TIME COMMAND

0 501 41 1 15 0 364 472 114d9c S v01 0:00 -bash

0 501 121 41 29 0 64 208 0 R v01 0:00 ps -l

In the shown o/p, PPID (Parent Process ID) column shows which process started that particular process.

U can use 'ps -aefH' to get a hierarchiel list of processes .

If UNIX95 is set in the environment to 1, then you should be able to use the -H option on ps -efH for example to see child processes.

What about the child processes are you interested in?

thanks to ALL

I mean exact to see all zombie processes executed via perl using:
opens, system and backticks.

some perl functions collect their child processes automatically and they must wait to be push manually or to push other processes.
