*Explain the jokes and references in the [[#Undocumented commands]] section and the sections below it.
*Find a better way to represent the comic, other than the current image. (screengrab maybe?)
*Add this comic to more categories.
*Describe the website interface a bit, such as the links at the bottom.}}This is another one of Randall's [[:Category: April fools' comics|April fools' comics]]. On April 1, 2010, [[Randall Munroe|Randall]] altered the [https://xkcd.com xkcd.com] website to mimic a {{w|Unix}} {{w|command-line interface}}. This interface is still available on [https://uni.xkcd.com uni.xkcd.com] and the source code is [https://github.com/chromakode/xkcdfools available on GitHub]. The comic [[721: Flatland]], released on March 31, 2010, was still up on April 1, 2010, but was unrelated to the Unix interface. The terminal only lists a few available commands, but most commands are undocumented.
