Here is some similar code that various monks posted awhile back. There are a few varieties of an isEmpty() sub 
#!/usr/bin/perl
# Returns:
# 1 - empty
# 0 - not empty
# -1 - doesn't exist
# Definition of "empty" -- no files/folders/links except . and ..
sub isEmpty{
  my ($dir) = @_;
  my $file;
  if (opendir my $dfh, $dir){
     while (defined($file = readdir $dfh)){
        next if $file eq '.' or $file eq '..';
        closedir $dhf;
        return 0;
     }
     closedir $dfh;
     return 1;
  }else{
     return -1;
  }
}

#######

sub isEmpty1 {
 opendir(DIR,shift) or die $!;
 my @files = grep { !m/\A\.{1,2}\Z/} readdir(DIR);
 closedir(DIR);
 @files ? 0 : 1;
}

print isEmpty1('./dir') ? "empty\n" : "not empty\n";

#################

sub isEmpty2 {
    return undef unless -d $_[0];
    opendir my $dh, $_[0] or die $!;
    my $count = () = readdir $dh;    # gets count thru ()
    return $count - 2;     #maybe not the best way of removing . and .
+.
}
