Sudowoodo reminding you to be careful when using sudo

Remember the lecture that you received when you first used sudo?

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.

It's a pretty nice warning, unfortunately, it only appears once. You can edit the sudoers file to make it permanent. Open the fine by running sudo visudo and then modify it to have the following line.

Defaults    lecture=always

You can also set a custom lecture, for instance, an ascii image of sudowoodo. Create a new file with the message to be displayed and set lecture_file to wherever the file is (e.g. /etc/sudoers.lecture).

# (replace the path with your own)
Defaults    lecture_file=/etc/sudoers.lecture
