I am confused with the actual use cases of the options

- :force
- :noop
- :verbose

Basically I was reading and trying some methods in the FileUtlis class
today and some examples here
http://www.ruby-doc.org/stdlib-2.0.0/libdoc/fileutils/rdoc/FileUtils.html#method-c-mv

made me confused... I am trying to understand why and when should anyone
consider to use such options with the method?

FileUtils.mv Dir.glob('test*.rb'), 'test', :noop => true, :verbose =>
true

FileUtils.mv Dir.glob('test*.rb'), 'test', :noop => true

FileUtils.mv Dir.glob('test*.rb'), 'test', :verbose => true

What are the differences between these 3 lines ?
