Ways to find File MetaData information?

ruby-talk
1

Hi,

Is there a way were we can find about the "meta data information" of an
existing file in the directory using ruby, like

1)When the file was created,
2)When was it modifed
3)when was it accessed. etc.

ie. If we pass the "name/location of the file" it should print the
creation / modified time of that particular file.

Thank You,
Dinesh

To the best of my knowledge, Unix / Posix file systems only give you a
modification date (your OS may differ :). You can access that using some
of the class methods of File. You'll probably be "feeling lucky" at
google if you throw it "ruby File class".

Yes, there is: http://www.rubycentral.com/ref/ref_c_file.html
Just look for the *time methods.

Yes, there is: http://www.rubycentral.com/ref/ref_c_file.html

That page has docs for Ruby 1.6. You may prefer to look at the 1.8.4 (i.e. current stable release) docs:

http://ruby-doc.org/core/classes/File.html

class File - RDoc Documentation

Oh, I would definitely prefer that :slight_smile: thank you!

I was using the other one simply because it was listed here:
Ruby Programming Language (which I think it's the 'official' Ruby
site? but I may be wrong there as well, I'm pretty new to Ruby), the
second link under 'Documents'.

Thanks again!

and have a good night everyone,
