Read a file containing 1 website address per line, and open each in the default browser.

popsites.rb

#!/usr/bin/env ruby
require 'rubygems'
require 'launchy'


if File.exists?(ARGV[0])
  sites = File.open(ARGV[0])
  sites.each { |line| Launchy.open(line)}
else
  abort "No link file found (#{ARGV[0]}), usage is 'popsites <linkfile>'"
end

What an amazing gist.
