Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I want to create a user with administrative privileges and all the regular setups like home directory.

  1. Is there a adduser parameter to give the user sudo powers automatically?
  2. What are the default settings for adduser? Will it automatically create home directories and all the other things without extra parameters? (i.e. is adduser <username> enough?)

you should use useradd for a new user not adduser. –  JizoSaves Apr 14 at 23:02

Add the user to the sudo group with:

adduser <username> sudo

(If you're running Ubuntu 11.10 or older, use the admin group.)

Default values are stored in /etc/adduser.conf, you can check them with

less /etc/adduser.conf

To create a user and add it directly to the sudo group use

adduser <usernane> --group sudo

(Again, use admin in place of sudo for 11.10 and earlier.)

Have a look at all the options you have with adduser here.

adduser --force-badname <username> admin –  Oxwivi Oct 21 '11 at 14:22
    
I believe so, yeah, or adduser --force-badname <usernane> --group admin –  Bruno Pereira Oct 21 '11 at 14:24

This is the first line of using -D: Option d is ambiguous (debug, disabled-login, disabled-password). adduser interprets it as a mistake and tells you all the flags and options you can use . Definitely got nothing to do with defaults. –  Oxwivi Oct 21 '11 at 16:31

To create a new user with admin privileges in Ubuntu 12.04 and later:

adduser <username> sudo

In Ubuntu 11.10 and earlier, use this instead:

adduser <username> admin

To modify a existing user (12.04 and later):

sudo usermod -aG sudo <username>

(Or for 11.10 and earlier: sudo usermod -aG admin <username>)

-a stands for append whereas -G stands for groups. With the -a and -G flags as shown above, the sudo (or admin) group will be added to the list of groups of which the user is a member.
