requirements-dev.txt obfuscating bash scripts is almost a noop Aug 21, 2016


Can you beat the Unix pipes?



  • State-of-the-art terminal graphics
  • Procedurally generated sound effects
  • Adjustable difficulty to challenge beginners and pros alike
  • Hours of engaging gameplay


  • Pentium processor or higher
  • Unix-like operating system with a modern terminal (xterm, UTF-8)
  • bash 4.0+ or compatible shell


  • Linux operating system supporting ALSA
  • Sound Blaster 16 or higher
  • Speakers


Run it normally:


Press SPACE for things to happen.

Press q to quit.

You can change the effective screen width by passing an argument:

./ 120

Lower values make the game more difficult. Anything below 80 is probably not for the faint of heart.


I only see gibberish, and then the game ends.

Your bash is too old. This most likely means you're running OSX and you'd want to use Homebrew to install an up to date one:

brew install bash

Check that bash --version is at least 4.0 and run the script again.
