Introduction

The page is build to work like a Unix-Terminal, including:

• 216 commands such as ls, cd and of course cowsay
• a file-system that you can navigate and manipulate
• TAB-Autocompletion (TABA) and Command-Validity Checking (CVC)
• multiple ways to get rickrolled
• all changes made are locally saved (using the LocalStorage API)
• very cute turtlo animal to keep you entertained

fun stuff to try

• plot your favorite equation using plot tan(2x) (and hear them!)
• solve your favorite equation using solve x*x=10
• feel like a hacker using cmatrix
• let the cow say something using cowsay
• convert a picture into ascii using img2ascii
• set and get key-value pairs on the server using set and get
  • these values are saved globally for all users to see
• most of your favorite unix-commands should do something
• shutdown the website using shutdown
• see your command history using history
  • execute a command from your history using !<index>
• spawn turtlo using turtlo and watch it do stuff
• convert your favorite image file to another format
  1. upload the file using upload
  2. convert it using convert <filename>.<old_ending> <filename>.<new_ending>
  3. download it using download <filename>.<new_ending>
• play fun terminal-style games
  • list all available games using games
  • view highscores using highscores <game-name>
• generate fake whatsapp conversations using fakechat

and so much more
