instead of usermod -G group; to add to group. you could
usermod -G - group; to remove from group
just a thought...
but as has been pointed out, it is trivial to write a script
that would automatically go out and modify /etc/group
on even a large number of boxes.
This is rough, needs polishing, use at own risk, blah blah...
BOXES="server1 server 2 server3. . ."
for box in $BOXES
do
{ sleep 5;echo "username";sleep 2;echo "password";sleep 2;
echo"sudo do some command left as exercise for reader";
sleep 3;echo "exit"; } |telnet $box 2>>/tmp/rcmd.error 1>/dev/null
done
