AIX Unix.. number of users on system in a particular group
Does anyone know what pipe string might be used to determine how many people are logged onto an AIX system where a group ID begins with lets say 4.
In other words, I am looking to query the system for the number of people currently logged onto a system that belong to any group starting with 4. Could be 400, 4102, 444, etc.
This will give you a list of users and gid starting with 4 - modify it for your needs ( sorry it's what I use to write scripts in).
Code:
#!/bin/csh
set allusers="`who -q`"
foreach xx ($allusers)
if ("$xx" == "#") then
exit
else
# find info on user
set mygid=`grep $xx /etc/passwd|awk -F: '{print $4}'`
if ("$mygid" != "") then
set first=`echo $mygid|awk '{print substr($0,0,1)}'`
if ("$first" == "4") then
# let me know who
echo $xx" "$mygid
endif
endif
endif
end
Also note it will only give you folks that are in the password file - if you're using NIS, you would have to change where it's looking.

I am auditing an older AIX system. As it stands, I can login remotely to the system using the Maestro application's user account. This is BAD. The administrator claims that he cannot disable the remote login, because it will... (1 Reply)
Is there a command or better combination of cmds that will give me the list of Unix users in a particular Unix group whether their primary group is that group in question (information stored in /etc/passwd) or they are in a secondary group (information stored in /etc/group).

7. Post Here to Contact Site Administrators and Moderators
I received an email claiming to invite me to some sort of user group connected through this forum. I did not click the link because the email is of dubious appearance. Is this group legit and is there other information about it someplace?
Thank you. (4 Replies)
