Get Date Modified value for a directory (folder)

[Hayato Iriumi]

Hello, folks.
I'm trying to find out a way to get "Date Modified" value for a
directory on Windows. Is it possible to get the value from Ruby?

The purpose of it is that I would like to get the newest sub directory
in a directory. If anyone knows a sleek way of accomplishing this in
Ruby, I'd appreciate it.

TIA

I was trying to get modified date/time for a remote directory and the
way you showed me worked only when I mapped the drive, so it's all OK,
but I just wanted to let the community know that it doesn't seem to work
if you specify the path like...

puts File.stat('\\\\remoteMachineName\\Test\\Dir1')

When I do it, I get Errno::ENOENT: No such file or directory -

Again, when I map the network folder, it works OK.

OOPS, the sample code was wrong. It should be...

puts File.stat('\\\\remoteMachineName\\Test\\Dir1').mtime

It still doesn't work, however.

Hello,
After I read your reply, I gave it another try. It's working now! I
don't understand why it wasn't working last time, but now it's all good.
I might have had some wrong code?

Anyway, thanks for taking your time to try it out.

Hi Iriumi,

This is a reply to myself.

When I did...

puts File.stat(rootDir + '\\' + subDir).mtime

I got an error... but when I did...

dirPath = rootDir + '\\' + subDir
puts File.stat(dirPath).mtime

It worked. Weird...

What are the exact platform, version and patchlevel, which is
given with `ruby -v'? One-click Installer?
