I have been a away from Perl for a few months and I'm still learning but finding it frustrating to pick it up again. I have two problems, the first is I would like to send a list of directories to an out put file and the second is i would like not to include the . and .. directories. 
#!/usr/bin/perl -w
use Cwd;
my $dir = getcwd;

my $dirs = "/opt/DSPKG";
          opendir(BIN, $dirs) || die "Can't open $dirs: $!";
          my @array = grep { -d "$dirs/$_" } readdir BIN;
foreach my $file (@array) {
open(MYFILE, ">/tmp/pkgtest") || die "cant open pkgtest: $!";
print "$file\n";
}
