Do you spot anything wrong in the below line,for some reason the for loop is executed even for the element "." in @folders

foreach my $folder (grep {$_ ne "."}@folders) { }

    Insofar as I understand what you're trying to do, it looks OK:

    >perl -wMstrict -le "my @folders = qw(foo .foo foo.bar foo. . .. ...); ;; foreach my $folder (grep { $_ ne '.' } @folders) { printf qq{'$folder' }; } " 'foo' '.foo' 'foo.bar' 'foo.' '..' '...'
