I don't think there's any POSIX defined method for this (even id -Gn, which would be the equivalent of groups, is not defined in POSIX afaik, though may be more reliable between linuces). Even then it only supports only one user at a time, but that's not really such a hinderance, just a little more foo in the shell snippet: for g in $(for u in $(echo $users); do id -Gn $u; done); do echo $g; done | sort | uniq -c | sort -n arguably this is starting to stretch the boundaries of what could be called a "one-liner" :) sean ___________________________________________________________________________ Philadelphia Linux Users Group -- http://www.phillylinux.org Announcements - http://lists.phillylinux.org/mailman/listinfo/plug-announce General Discussion -- http://lists.phillylinux.org/mailman/listinfo/plug
