in thread run program until directory is not empty

You can use this ; 

my $dir = "/var/tmp/monk";
chdir("$dir") or die "$!";
opendir(BIN, $dir) or die "Can't open $dir: $!";

#Read Directory


readdir DIR; # reads .
readdir DIR; # reads ..
if (readdir DIR) { #now there should be a file or folder
  print "it's not empty";
}
else {
   print "it is empty";
}
close DIR;

    #check() ;
  }
}

check() ;

    P.S. This takes the previous example and makes it recursive which is what the OP asked for.
