Find processes by parent PID on Solaris

Question

I'd like to find all processes running on Unix (Solaris) with a certain PPID. Is this possible using the ps command?

Answer 1

Alternatively, you could always perform a grep on the output of the process list;

ps -ef | grep XXXX, where XXXX is your PPID.

This will at least give you a list of processes with that number, and knowing that PPID should be the third column, lead you to your specified Parent Process ID.

Answer 2

On Solaris 5.10:

For the current process

ps -o ppid -p $$

For a process with PID 12345

ps -o ppid -p 12345

Answer 3

On Ubuntu (12.04 at least) you can use the --ppid option. E.g.

ps --ppid 1234
