That will only work for local users. The answer you really want is "getent passwd". This handles everything nsswitch.conf does (NIS, LDAP, xyzzy, whatever). To get just a list of usernames: getent passwd | cut -d: -f1 | sort -u What it _doesn't_ do is handle specialised authentication; just because a person may have an account on a box doesn't mean a person can login or otherwise access the box. Naming services do _not_ match authentication and authorisation services. However, if your environment is that complicated then you shouldn't be asking such simple questions on this list :-) For a simple environment, or even a moderately complicated one (NIS, NIS+, LDAP with no specialised PAM rules) then "getent passwd" will do the job. -- rgds Stephen _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
