Also – if you are actually managing 190 servers using passwd files ... "oh my!" Your life would be made very-considerably easier if you could switch those machines to use a different, centralized source of authentication/authorization such as LDAP (MS OpenDirectory) or Kerberos.
Comment on Re: parse /etc/passwd and output it as csv in hundred servers
this is a new mission I got and yeah the former sys admin administer each server passwd locally. so I need to clean up all the one that have left the cie and still on the passwd and indeed move to ldap.
