在 Ruby 中创建一个空文件：相当于“touch”？

创建一个的最佳方式是什么emptyRuby 中的文件？

类似于 Unix 命令的东西，touch https://en.wikipedia.org/wiki/Touch_%28Unix%29:

touch file.txt

FileUtils.touch http://apidock.com/ruby/FileUtils/touch/class looks like what it does, and mirrors^* the touch command:

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

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