  • If you use sudo adduser to add a new user and you want that user to be able to use sudo, you should add them to the sudo group.  There are a number of ways to do that, like with sudo adduser their_username sudo.  The official way to add someone to a bunch of groups at once would be sudo vigr (if you know how to use vi), or I just use sudo nano /etc/group (which you would not normally do if more than one admin could edit the file at the same time). /etc/group is a comma separated list of users for each group like:

    Note that:

    sudo halt is same as sudo shutdown -h now

    sudo reboot is same as sudo shutdown -r now
