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}}
