sudo allows privilege escalation for non root users to perform restricted actions while in a locked down user environment.

Emerge

# emerge sudo


Configuration

Passwordless

The sudo configuration file is located @ /etc/sudoers.

$su -c 'nano /etc/sudoers'


Remove the # in the line....

%wheel ALL=(ALL) NOPASSWD: ALL

Add your user to the wheel group to enable sudo:

$ su -c 'gpasswd -a $USER wheel'


Either log out, and in again or restart:

$ su -c 'shutdown -r now'


Bash Completion

Users that want bash completion with sudo need to run this once.

$ echo "complete -cf sudo" >> $HOME/.bashrc
