Full Discussion: Get all child processes of a process
Top Forums Shell Programming and Scripting Get all child processes of a process Post 302974671 by MadeInGermany on Thursday 2nd of June 2016 04:03:43 AM

I usually have taken -e not -A for portable ps.
HP-UX needs environment variable UNIX95 to take the -o option.
If your pid is 4711 then a portable command to find its children is
Code:
UNIX95=1 ps -e -o ppid= -o args= | awk '$1==ppid' ppid=4711
