how to check user id when running ps

[Connors]

Hi :
I am new to unix, and some one has asked the question I don't know the answer; the question is - How can you find the user group id when you use ps command?

thanks Connors

hi connors,

I think you'll have to look up the users group id in the /etc/passwd file

take the users name from the ps output, and then grep for it in /etc/passwd like this

grep mike /etc/passwd

the first number is the user-id, the second is the users primary group-id Mike

Is that a haiku?
I never could get the hang
of writing those things.

For example, entry from /etc/passwd

userid:*:104:20:Name,,,:/home/homedir:/usr/bin/sh

Thus the 20 is the group-id.

Try this script

for process in `ps -ef | tail +2 | cut -c12-19`
do
owner=`ps -fp | tail +2 | cut -c1-8`
echo ""
echo "OWNER "$owner
echo "GROUP "`id -gn $owner`
echo "PROCESS "`ps -p |$process | tail +2`
done

I havn't tried this on HP, so you may need to modify the 'cut' values and maybe the 'ps' options.
The 'tail +2' eliminates the header lines.
