Unix is an operating system that has been around for a long time. The most popular Unix clone is Linux.

Unix Philosophy Edit

an important part of the unix philosophy is that tools should be built to perform one basic task well. Complex tasks can then be solved by joining those simple tools together.

A few Unix commandsEdit


  • ls - displays items in the current directory.
  • cd - moves to the directory specified in its arguments.
  • .. - previous directory.
  • . - current directory.
  • ~/ - home directory.
  • something* - Filename completion.

Dangerous commandsEdit

Fork bomb in a Unix shell - causes system to 'freeze', due to it being a wabbit:

   :(){ :|: & }; :

Erase whole system, and make it crash:

   sudo rm -rf
