If however you have users with their primary group set to something other than the login id - e.g. "admin" or "marketing" - then you need to look in the /etc/passwd file as well because these users don't appear in the comma separated list outlined above. To check the /etc/passwd file, you have to determine the group id value, and then scan the /etc/passwd file looking for that value in column 4. This will give you a list of users whose primary group is the group value you're interested in. Cheers, Ian -------------- next part -------------- A non-text attachment was scrubbed...
