If you're looking for a way to find the "newest" file, without looking at all the files (or at least, their metadata), there isn't.
You could do something like (untested):
use File::Spec;
my %cache;
foreach my $file (`find d:\\Teszt -type f`) {
my $age = -M $file;
my ($vol, $dir, $name) = File::Spec->splitpath($file);
if (exists $cache{$vol, $dir}) {
next if $age > $cache{$vol,$dir}[1];
}
$cache{$vol,$dir} = [$file, $age];
}
foreach my $newest_file_in_directory (map {$$_[0]} values %cache) {
... process file ...
}
I'm using
`find` because I've never had a need to learn the File::Find syntax.
