even a simple readdir should do the trick

#!/usr/bin/perl -w use strict; my $dir = '/some/dir'; my $file_re = qr/^(?:\.+|[a-zA-Z]{4}-[0-9]{8})$/; opendir(DIR, $dir) or die "opening $dir: $!\n"; for ( grep(!/$file_re/, readdir(DIR)) ) { # deal with non conforming file names here } closedir(DIR);

use perl;

[tobyink]: Why are you returning $_ n your grep block? You should return a boolean.
