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.

# whats the dot symobl indicates.
the dot represents the current/working directory/path http://en.wikipedia.org/wiki/Path_(computing)
some simple examples,
irb(main):192:0> puts `ls -la .`.grep(/\.$/)
drwxr-xr-x 12 root root 4096 Aug 7 10:30 .
drwxr-xr-x 30 root root 4096 Jul 9 09:47 ..
=> nil
irb(main):193:0> puts `pwd`
/root
=> nil
irb(main):194:0> `ls -la .` == `ls -la /root`
=> true
irb(main):195:0> `ls -la .` == `ls -la /etc`
=> false
and directories are just files (albeit special), so
irb(main):199:0> File.mtime "."
=> Tue Aug 07 10:30:53 +0800 2007
irb(main):200:0> File.mtime ".."
=> Mon Jul 09 09:47:20 +0800 2007
irb(main):201:0> File.mtime "/root"
=> Tue Aug 07 10:30:53 +0800 2007
irb(main):207:0> File.stat(".") == File.stat("/root")
=> true
irb(main):208:0> File.stat(".") == File.stat("..")
=> false
irb(main):209:0> File.stat("/root") == File.stat("..")
=> false
irb(main):210:0> File.stat("/") == File.stat("..")
=> true

OOPS, the sample code was wrong. It should be...
puts File.stat('\\\\remoteMachineName\\Test\\Dir1').mtime
It still doesn't work, however.
FYI

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.

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?
