Users, adding

Revision as of 07:08, 21 May 2009

http://www.textpasvierc4tb.com There are several methods that are commonly used to add users to a FreeBSD system.

Using pw to add a new user

samizdata## pw useradd username -g groupname -s /bin/csh -d /home/username

The command shown above will add a new user account named "username", assign the group "groupname" as the new user's primary group, set the C shell as its default shell on login, and set its home directory as "/home/username". It will not copy any .profile or similar files from /etc/skel, create any directories, or anything else - all pw does is manipulate the system user database for you.

Using adduser to add a new user

adduser can be run with no arguments, and will present you with a prompt for each question that needs to be answered in order to create the user that you're going to create
