Installing and Configuring sudo on Gentoo

It is not always good to use root constantly, for this sudo exists. To install it simply run the command below, -a is optional which is the same as --ask, Portage asks you if you want to continue and also shows the package(s) that will be compiled.

su
emerge -a sudo

After that fill in the field [NAME_YOUR_USER] with your user number

export my_user="[NAME_YOUR_USER]"

Then, run the command below

sed -i "/^root ALL=(ALL) ALL$/a ${my_user} ALL=(ALL) ALL" /etc/sudoers

The first time you use sudo this message will appear:

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:
 
    #1) Respect the privacy of others.
    #2) Think before you type.
    #3) With great power comes great responsibility.
 
Password: ## (Enter the user password, not root!)

Now just use sudo with the password of the user you chose!
