thanks ! I discovered that the ps -ppid "parentID" would return the
list of child pids which works, but thanks..!
You should bear in mind that that will probably be a GNU "ps" specific option.
On Fedora you're fine; on other UNIX platforms that may not be available.
I'm quite fond of "ps axf"; it is easy to type and informative, and shows the
parent-child stuff visually in the listing, very nice. It (the "f" option) is
also GNU ps specific.

A test app does a fork, creates children processes.
Is there a way to view the procTBL "ps" to be able to see that a
process is a "child" process?
I know you can see when a child has stopped, but the parent is still
running.. but is there a way to see if there are "running" children,
some attribute that denotes i'm a child?
Or, is there some attribute that denotes the process has running children?
Every process has a parent process id (PPID), allowing you to deduce the
parent-child relationships.
The GNU ps "f" option will display the process tree with parent-child
relationships.
