<pre><nowiki>

# nicl -raw /var/db/netinfo/local.nidb -create /users/my_user

# nicl -raw /var/db/netinfo/local.nidb -create /users/my_user uid my_user_id

# nicl -raw /var/db/netinfo/local.nidb -create /users/my_user realname "My User Real Name"

# nicl -raw /var/db/netinfo/local.nidb -create /users/my_user passwd "my_user_passwd"

# nicl -raw /var/db/netinfo/local.nidb -create /users/my_user gid 20

# nicl -raw /var/db/netinfo/local.nidb -create /users/my_user shell "/bin/bash"

# nicl -raw /var/db/netinfo/local.nidb -create /users/my_user home "/Users/my_user"

# nicl -raw /var/db/netinfo/local.nidb -create /users/my_user _writers_passwd my_user

# passwd my_user

# ditto /System/Library/UserTemplate/English.lproj /Users/my_user

# chown -R my_user:staff /Users/my_user

# nicl -raw /var/db/netinfo/local.nidb -read /users/my_user

# nicl -raw /var/db/netinfo/local.nidb -append /groups/wheel users my_user

# nicl -raw /var/db/netinfo/local.nidb -append /groups/admin users my_user

</nowiki></pre>
