In all likelihood the system follows the default approach of setting the
primary group to be the user's personal ground. If that is the case
then you're correct in providing a simple solution as requested. I just
wanted to make Tim aware that if his user's have primary groups other
than their personal groups - e.g. "admin" or "marketing" - then there
isn't a simple answer (not that the answer is all that hard).
Here's a script I knocked up to do it - although there can be
duplication and output formatting isn't perfect:-
#!/bin/bash
#set -x
# $1 is the group to test
if [ "$1" = "" ]; then
echo "Which group?"
exit 1
fi
groupid=$(getent group $1 | cut -d: -f3)
grouplst=$(getent group $1 | cut -d: -f4)
for User in $(cat /etc/passwd | cut -f1 -d:)
do
if [ $(id -g $User) = $groupid ]; then
grouplst="$(echo $grouplst),$User"
fi
done
echo "Members of group $1 are: $grouplst"
exit 0
