cat.rb it’s just a little clone -and probably buggy- of the classical tool ‘cat’ present at every good named unix-like system. This is my first implementation of any of these tools. It’s been written in Ruby(is there another?), and just uses libraries which comes with an standard setup of the Ruby interpreter.

The original idea came from Mauro, who suggested to re-implement a few utilities from classical unix-like systems in many programming languages as we can.

The cat.rb source code can be found at:, where also can get various interesting implementations of ‘cat’.
