FYI, this tips is for newbie like me who is still learn how to use FreeBSD or people who was forgot about managing they FreeBSD system :-D .

When u want to update user’s group after editing /etc/passwd or /etc/master.passwd, you don’t have to reboot your system.

For example, if you wanna change group for user chaidir into becoming wheel, edit /etc/passwd like this:

before

chaidir:*:1001:1001:chaidir:/home/chaidir:/bin/sh

after

chaidir:*:1001:0:chaidir:/home/chaidir:/bin/sh

Then after editing /etc/passwd, use this command :

pwd_mkdb /etc/master.passwd

or

pwd_mkdb /etc/passwd

pwd_mkdb is an utility to generate the password database. This utility can also be used for updating your password after changing user’s password (passwd).

I made here for forgetful person like me.. so, when i forget something, I will see this tutorial again. :-)
