Fellow Monasterians,

I comfortable working on the command line to do this, but I've created Web app that uses CGI's upload method to upload a file from the browser. On the way, if the subdirectory 'foobar' doesn't exist, my script makes it.

I have the permissions working, but I'm getting the desired ownership of:

drwxrwx--- 2 www-data sftp  4096 2008-07-28 22:18 foobar
[download]

instead I'm ending up with:

drwxrwx--- 2 www-data www-data  4096 2008-07-28 22:18 foobar
[download]

Likewise, the file ownership itself is the same:

-rwxrwx--- 1 www-data www-data 27034 2008-07-28 22:32 wilma.jpg
[download]

Here's my script:

mkdir('foobar') or die...;
my $mode = 0770; chmod $mode, 'foobar' or die...; 
chown 'www-data', 'sftp', 'foobar' or die...;

my $upload_filehandle = $query->upload($upload);
open UPLOADFILE, ">$upload_dir/$filename";
binmode UPLOADFILE;
while ( <$upload_filehandle> ) {
   print UPLOADFILE;
}
close UPLOADFILE;
$mode = 0770;   chmod $mode, "$upload_dir/$filename";
[download]

Is this even possible? Thanks.

Update: Fixed typo

Update 2: per comments of the good monks, I changed chown 'www-data', 'sftp', 'foobar' or die; to chown -1, 1003, 'foobar' or die; (1003 being the numeric equivalent for the group) for success.
