How to add sudoers
Since we should not run as root we need sudo and to add our user to the sudoers group. This is how you do it.
The prerequisite is that you have sudo installed and you are logged in as root.
$ usermod -aG sudo username
Example:
usermod -aG sudo pfalken
To verify issue the command: groups username and you should see sudo in the list.
groups pfalken
pfalken, sudo
