Ruby is an awesome, powerful little language.
I needed a ’time’ command for windows to measure the execution time (in seconds) of a command. Should be trivial, but I’m not Windows API savvy. Here’s the full script in Ruby:
t1 = Time.new
IO.popen(ARGV.join(' ')) { |pipe| puts pipe.gets }
t2 = Time.new
puts "Execution time: #{t2 - t1} seconds"
Simple, direct, and obvious. LOVE IT!
