Ruby Command-Line Arguments

If you’re writing a serious Ruby application (not a Rails application necessarily), this question may apply to you: how do you access command-line arguments in Ruby?

Ruby provides an array called ARGV (all upper-case). This array contains all the command-line arguments; so if you run this:

ruby script.rb first second third

… then ARGV.length is 3, ARGV[0] is “first”, ARGV[1] is second, and ARGV[2] is third.
