There will only be one process with a certain PID. The PPID doesn't really narrow any further.

You are right .. there will be only one process with a certain PID.. but that process could have some child process and if grep for PID.. all will be listed,that is the process itself and the child process of that process..
and if you grep it along with PPID you will get the desired result.. thats what i was looking for

Code:

ps -ef | grep "$pid[ ]*$ppid"

Sorry for the late response. You already got the reply. I have started to love AWK and trying to learn the same. So can we do something like this:

Code:

ps -ef | awk '{if ($2 == 4063 && $3 == 1) {print $0}}' # where $2 is for PID field and $3 is PPID field
 
# Output:
user      4063     1  0 Xxxxx ?        00:00:00 process_name

(I have hidden some values for obvious reasons. It may be LAME still )
