149: Sandwich
| Sandwich |
 Title text: Proper User Policy apparently means Simon Says. |
[edit] Explanation
On a UNIX-type system, users can be assigned all kinds of rights, for example access to certain directories or files, executing certain commands etcetera. The “sudo” command overrides these policies by executing the command typed behind it as if the user were an administrator (the Super User) of the system. To prohibit abuse of the command, the user must be in the "sudoers" group, and the user first must type their password before the command will be executed.
In the comic, Cueball is demanding a sandwich from a friend. Not being properly asked, the friend denies the request. Cueball then (ab)uses the sudo command on the friend, which then has no choice but to go and make the sandwich, because Cueball has all rights. The image text references this abuse, noting that an administrator should set a proper use of the command in order to control his system.
"Simon says" is a children's game in which a leader gives various commands which must be followed iff prefixed with "Simon says". Wikipedia suggests "Simon" may be the powerful lord Simon de Montfort, or a corruption of Cicero, both of whom were influential politicians of their day.
This comic was referenced in a guest comic 824.

sudo !!outputs the previous command with sudo into your bash (other shells as well) history, so to bash what you said was "sudo make me a sandwich" not "sudo !!". lcarsos (talk) 16:46, 29 October 2012 (UTC)
sudo requires user password, not admin password, but you need to be in sudoers file. --JakubNarebski (talk) 12:14, 15 December 2012 (UTC)
