Need something to tell me if a file (actually a word document) has been added to a directory. I want to run this in a cron job where it runs twice a day and only sends me a message when a new document has been added to the directory. Here is an attempt as I would like to do this in a hash but cant get it to work. I know I need some sort of work with "oldfiles" set some other way and sending a message if I get a new file. Please help me on this?? 
#!/usr/local/bin/perl
my $mydir="/path/dirname";
use strict;
opendir(DIR,$mydir) || die "Could not open $mydir: $!\n";
my %files=map {$_,1} readdir(DIR);
my %newfiles = "";
foreach my $file (keys %newfiles)
{
        unless (exists $oldfiles{$file}) new_file();
}
