mtime for ftp

[Peter Bailey]

Hi,
I'd like to go to an ftp site and check the dates of available files
there. (I only want today files.) I see that ftp, from 'net/ftp' has an
mtime method. But, I can't seem to get it to work. Here's what I've
tried.

...
xmlfiles = ftp.list('*.xml')
xmlfiles.each do |xmlfile|
puts xmlfile
puts ftp.mtime(xmlfile)
end
...

I get something like this:

Exception: 500 'MDTM -rw-rw-r-- 1 bna staff 43945 Oct 19
08:50 lobbyreg-20071010-160009.xml': command not understood.

Just doing the "puts xmlfile" works fine, just not the mtime thing.

Thanks,
Peter

I don't think every server supports MDTM.

Thanks. I don't even know what MDTM is. It's obviously part of Ruby's
ftp, though, isn't it?

Actually, it looks like you're not passing the filename, but are
passing a bunch of file metadata along with the file's name.

I presume MDTM is the command you send to the FTP server to get it to
return the modification time, like GET.
