Writing a Command Line Tool in Ruby

This article is a technical tutorial on building a command line tool in Ruby from scratch. It covers creating an executable script, handling command-line arguments using ARGV, and implementing commands and options with Ruby's built-in OptionParser library. The author demonstrates a practical example of a tool that accepts commands like 'say_hello' and uses flags to customize output.
