Refactor, Refactor, Refactor

Original Code

from_file, to_file = ARGV

puts "Copying from #{from_file} to #{to_file}"

# we could do these two on one line, how?

in_file = open(from_file)

indata = in_file.read

puts "The input file #{indata.length} bites long"

puts "Does the output file exist? #{File.exist?(to_file)}"

puts "Ready, hit RETURN to continue, CTRL-C to abort."

$stdin.gets

out_file = open(to_file, 'w')

out_file.write(indata)

puts "Alright, all done."

out_file.close

in_file.close

Extremely Refactored Code

File.new(ARGV[0], 'w').write(File.read(ARGV[1]))
