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.
