One-liner copy file in ruby
Is there a one-line way to copy a file to another in Ruby, ensuring the files are closed after the operation finishes?
The best I can come up with is this but I'm not sure the files are closed
open(ARGV[1], 'w').write(open(ARGV[0]).read)

File.write(ARGV[1], File.read(ARGV[0]))
is a bit shorter and will ensure the files will be closed.
