Title text: Proper User Policy apparently means Simon Says.
On a UNIX computer system, users can be assigned to all kinds of rights, for example rights to access to certain directories and files to execute certain commands. The sudo command overrides these policies by executing the command typed behind it as if the user were an administrator — the Super User, who can access much more of the system than a normal user.
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, who then has no choice but to go and make the sandwich, because Cueball has all the rights.
On a real UNIX machine, 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.
Simon Says is a children's game in which a leader gives various commands which must be followed if and only if (iff) the leader prefixes the command with “Simon says”. And though UNIX’s user rights management system, which one could refer to as proper user policy, is complex and powerful, people’s use of it often degenerates into merely prepending “sudo” to a failed command so that it will work. For example, sometimes a command to delete a file “rm -f /path/to/some-system-file” will fail because the user does not have enough permissions, but the user knows they really want to delete the file, so they simply repeat the command with “sudo”: “sudo rm -f /path/to/some-system-file”.
The title text compares the way the computer will run some commands if they are preceded with “sudo” to the way Simon Says players are supposed to follow orders if they are preceded with “Simon says”.
Alternatively, the title text might merely be referring to the similarity between Cueball ordering his friend around with “sudo” to the Simon Says game leader ordering other players around. Wikipedia suggests the “Simon” in the name of the game may be the powerful lord Simon de Montfort, or a corruption of Cicero, both of whom were influential politicians of their day.
