sudo

This article talk about sudo.

Introduction

To change some things of sudo, you need to use the special visudo.

Give full admin rights to a user

Copy the example line of the root user and paste it just bellow. Then change the root user on that line so that it match with you're username. The final result looks like this:

# User privilege specification
root    ALL = (ALL) ALL
david   ALL = (ALL) ALL

Note: Giving a user full admin rights is really dangerous. The user will have the same rights as root! Note also that proceeding this manner to give someone full adming rights (ake root), you should proceed another way, change the uid and guid of the user to 0, such as root has.

Give some more rights to a user

toto    ALL = NOPASSWD: /sbin/shutdown, /sbin/reboot, /usr/sbin/s2disk

Or if you want to allow everyone some programs:

ALL     ALL = NOPASSWD: /sbin/shutdown, /sbin/reboot, /usr/sbin/s2disk

Sudo can type sudo shutdown and the system will shut down.
