In this example we will add user name ‘mazsola’ to the BSD 2.11 system.

edit (vi) – /etc/master.passwd

mazsola::101:40::::A regular user:/usr/mazsola:/bin/sh

After this preparation step, execute the following sequence of commands:

cp master.passwd passwd
mkpasswd /etc/passwd
chpass mazsola

Changing user database information for mazsola.

chmod a+r /usr # (only first time, all user must be able to read their “..”)
mkdir /usr/mazsola
chgrp staff /usr/mazsola
chown mazsola /usr/mazsola
