==Explanation==
This comic was posted on {{w|Christmas Eve}}. While {{w|Christmas}} is principally a {{w|Christian}} holiday, celebrating the birth of {{w|Jesus}} on December 25, there are many traditions around it, among them {{w|Christmas Eve#Gift_giving|a tradition}} that on {{w|Christmas Eve}} {{w|Santa Claus}} will make his round delivering gifts to good children.

[[Rob]] sits behind a UNIX computer and tried to change his user account from his normal access to the access of a super user by using the command "{{w|sudo|sudo su}}". Sudo is a famous phrase in xkcd lore, made famous by comic [[149: Sandwich]]. Before allowing administrator access (as root user), it asks for a password. The field is blank because, in most UNIX systems, the characters of the password are not shown. Even though the password is correct, Rob's account is not in the list of accounts that can use <code>sudo</code> (the <code>sudoers</code> file). The error message says that the incident "will be reported" (usually to the system administrator, so they can see if someone is making repeated attempts at accessing administrator privileges).

In the comic, however, sudo and the system report the incidents to {{w|Santa Claus}}, who, in Christmas lore, makes a list of who is naughty and who is nice. If you are nice then you get presents, while if you are naughty, you get a lump of coal. When sudo reports to Santa that Rob's account is not authorized, he puts Rob on the naughty list.

The message "… is not in the sudoers file. This incident will be reported." is a real message that the <code>sudo</code> program used to output in this situation. It was changed in 2022 to "This incident has been reported to the administrator", citing this comic: [https://github.com/sudo-project/sudo/commit/6aa320c96a37613663e8de4c275bd6c490466b01][https://github.com/sudo-project/sudo/commit/9757d29a24ac1872872cf09757b0439c54089707].

In the title text, which is a parody of the famous Christmas song, "Santa Claus Is Coming To Town", <code>/var/spool/mail/root</code> is the root (superuser) mailbox on a Linux system.
