xkcd released a really original version of his site: unixkcd. It features a linux-like shell which you can use to navigate the comigs or go to other parts of the site. Some of the commands are not displayed and we have to figure out ourselves. Well, here I include a list of all possible commands, with some usage examples (where applicable). UPDATE: The site no longer features the unixkcd interface by default anymore, but you can still use it clicking here.


display <comic_id>: Displays the comic with id comic_id. display 721

next: Displays the next comic.

prev, previous: Displays the previous comic.

first: Displays the first comic.

last, latest: Displays the last comic (the latest).

random: Displays a random comic.

goto <comic_id>: Displays the comic 292 - “Go to”, and suggests: Did you mean “display”?

**cd :** cd's into the specified directory. The available directories are: _blog_ (also _blag_), _forums_ (also _fora_), _store_ and _about_. - If the directory doesn't exist => _cd: "" : No such file or directory_

**cat :** Prints the contents of the specified file. Available files are: _welcome.txt_ and _licence.txt_ - If no argument specified => _You're a Kitty!_ - If the file is a directory => _cat: "" : Is a directory_ \- If no file/directory exists => _cat: "": No such file or directory_

ls: Lists all available files and directories.

**rm =>** Removes the file from the filesystem.

rm -r filename => Removes recursively (so you can also remove directories).

reddit <comic_id>: Adds the specified comic number to reddit and then shows a reddit gadget with the number of votes for that comic. If you do not specify a number, then it adds the current location (the website root) to reddit, and shows the current number of votes.

[sudo] apt-get **[update upgrade dist-upgrade]**: Many things, as follows:
apt-get =>This APT has Super Cow Powers. apt-get <weird_command> => E: Invalid operation <weird_command**> apt-get [update upgrade dist-upgrade] =>** E: Unable to lock the administration directory, are you root? sudo apt-get update => Reading package lists… Done sudo apt-get upgrade: If you’re using any version of IE or Firefox, or your browser’s version is < 3, it shows a link with the words “To complete installation, click here.” The link will take you to http://abetterbrowser.org. Else, it shows the message: This looks pretty good to me. sudo apt-get dist-upgrade =>You are already running <os_name>. sudo apt-get moo: Shows a fancy ascii-art cow and the message: ….”Have you mooed today?”…

sudo : Executes the specified command if it exists (from the ones in this list). - If the command does not exist => sudo: “”: command not found - There’s a special variation:

sudo make me a sandwich => Okay.

man : Many things, as follows.

man last => Man, last night was AWESOME. man help => Man, help me out here. man next =>Request confirmed; you will be reincarnated as a man next. man cat =>You are now riding a half-man half-cat. **man =>** _Oh, I'm sure you can figure it out._

pwd => You’re in a mess of twisty passages, all alike.

find kitten => Shows the game from robotfindskitten.net

buy stuff => Enters the store (same as cd store).

your gay => Keep your hands off it!

ssh => ssh, this is a library.

**cheat =>** shows a link that says “*** FREE SHIPPING ENABLED ***”. The source code doesn’t do anything in particular, so if this is true the it is so just because shipping is free and not because you typed in this keyword.

wget => Enters the store (same as cd store).

curl => Starts loading “something”, never receiving a response.

**curl , wget =>**Loads the url inside an inline frame. Very useful if you wish to surf the web through unixkcd =)

poweroff, shutdown, reboot, restart => Must be root.

**sudo [poweroff shutdown]:** Check it out yourself! (reported by Adrian Díaz)
**sudo [reboot restart]** => Reboots the shell, first printing the following for a very short period of time:

Broadcast message from [email protected] The system is going down for maintenance NOW!

logout, exit, quit => Ends the shell session, showing the message “Bye.”

nano => Seriously? Why don’t you just use Notepad.exe? Or MS Paint? (reported by “n”)

**go ** _(reported by Joe)_

go => Go where? go down => On our first date? **go =>** _You cannot go _

kill => Terminator deployed to 1984 (reported by Nico Far)

sleep => The console will goes blank with the message “you take a nap”. After 3 or 4 seconds, it appears again with the message “You awake refreshed”. (yet another hidden reference, I believe - reported by Jon)

locate raptor => BEHIND YOU!!! (reported by ann and Melissa)

use the force luke => “__I believe you mean source.” (reported by Seng)

use the source luke => I’m not luke, you’re luke! (reported by Seng)

Keyboard Shortcuts

CTRL + W => Deletes the previous word in the terminal. CTRL + H => Deletes the previous character in the terminal. CTRL + L => Clears the screen. CTRL + A => Goes to the beginning of the line. CTRL + E => Goes to the end of the line.


The console also features a game. I will let the readers figure it out (or else its no fun). The commands are:

**look go light **


There is at least one thing you can’t do by typing anything, so I guess it falls more into the “cheats” category. Enter the following keys in sequence to see cumulative changes to the interface. You can repeat the cheat up to five times: [up] [up] [down] [down] [left] [right] [left] [right] [B] [A] Thanks Insignis for reporting it!

Wrapping Up

Yet another really original idea by xkcd, I loved it! Spread the word!! (you can use the floating links to the right). The sourcecode is available from the website or from github.


There’s some more commands I missed. If you know one or a few of them, please comment and I will update the list! Thanks to those that have already informed me about a couple of them.
