How to make lecture show up forever in sudo

if you love the “With great power comes great responsibility” message and want to see it every time you run a command, this is how you achieve that:

one should NEVER open the /etc/sudoers file with a normal text editor. always use sudo visudo.

1. open the /etc/sudoers file.

sudo visudo

2. add the following to the end of the file:

Defaults lecture="always"

3. save and exit the file.

you might need to kill your existing sudo session with sudo -k.

while you are here, you might also want to show asterisks when typing your password like so:

cinar@fedora ~$ sudo -v
[sudo] password for cinar: *************

or you might want to insult users who mistype their password. in either case, click the relevant link.
