Creating an empty file in Ruby: “touch” equivalent?

Question

What is the best way to create an empty file in Ruby?

Something similar to the Unix command, touch:

touch file.txt

Answer 1

FileUtils.touch looks like what it does, and mirrors^* the touch command:

require 'fileutils'
FileUtils.touch('file.txt')

^{* Unlike touch(1) you can't update mtime or atime alone. It's also missing a few other nice options.}
