<para>

The <command>newusers</command> command reads a file of user name and
|
|
clear-text password pairs and uses this information to update a group
|
|
of existing users or to create new users. Each line is in the same format
|
|
as the standard password file (see
|
|
<citerefentry><refentrytitle>passwd</refentrytitle><manvolnum>5</manvolnum>
|
|
</citerefentry>) with the following exceptions:
