Parent / Child Process id.

Pheroz Tengra — Fri, 21 Dec 2001 16:25:46 GMT

Does any one have a handy script to know the process id of certain background tasks and all of their associated child processes in KSH.

Thanks in advance.

ps -ef | grep "name of process" | awk ' { printf "Process id = %s Parent Process id = %s\n", $2, $3 }'

Sam will show you this under Process Management, Process Control.

If you want something you can call from a script, HP used to have a script called ptree. I cannot find it on my 11.0 install, but have a copy on another system, which I've attached.

You can use the -H option to ps, which requires the UNIX95 env var to be set. The following will give you the whole process tree, then you can look for your process under that.

# UNIX95= ps -eH

Hi

ps -ef | grep -v grep | grep | awk '{print $2,$3}'

From my machine:-

root@N-0/etc>ps -ef | grep -v grep | grep inetd | awk '{print $2,$3}'
17315 1
the 17315 is child and 1 is parent

Thanks for everyone's response. The awk/grep method is not adaquete, as that is already part of the ps header. However Mark Green's ptree script was what I was looking for.

Thanks Mark.
