sudo allows privilege escalation for non root users to perform restricted actions while in a locked down user environment.
=== Emerge ===
{{console|body=###i## emerge sudo}}
==== Configuration ====
===== /etc/sudoers.d/ =====
Instead of editing {{f|/etc/sudoers}}, you may drop individual configuration files into the {{f|/etc/sudoers.d/}} directory
===== Passwordless Sudoer =====
The sudo configuration file is located @ {{f|/etc/sudoers}}.  When editing this file be very careful to not introduce syntax errors.  Several other linux distributions use {{c|visudo}} to edit {{f|/etc/sudoers}}.
{{Console|body=$##i## su -c 'nano /etc/sudoers'}}
{{file|name=/etc/sudoers|lang=|desc=uncomment wheel group no password sudo|body=
%wheel ALL=(ALL) NOPASSWD: ALL
}}
Add your user to the wheel group to enable sudo:
{{Console|body=$##i## su -c 'gpasswd -a $USER wheel'}}
Either log out, and in again or restart:
{{Console|body=$##i## su -c 'shutdown -r now'}}
===== Disabling Root Access By Password =====
To better secure a system, one may desire to disable root logins by password.
{{console|body= $##i## sudo passwd -ld root}}
to access root:
{{Console|body= $##i## sudo su}}
Root can also be accessed by logging in via ssh keys, or as a restricted user then sudo su as above.
====Bash Completion====
Users that want bash completion with sudo need to run this once.
{{console|body=$##i## echo "complete -cf sudo" >> $HOME/.bashrc}}
==== Passing Environment Variables ====
To pass environment variables to the temporary root use the -E flag.
{{console|body=$##i## sudo -E echo 'hello world'}}
==== Passing Aliases ====
If your user has aliases you wish to use under sudo you must alias sudo with a space first:
{{console|body=$##i## echo "alias sudo='sudo '" >> $HOME/.bashrc}}
