You still have two bugs and two instances of poor programming.

• close doesn't work on directory handles. You need closedir .

• You'll stop iterating prematurely if you have a file named 0 (zero). You need to check if the result of readdir is defined. Check if it's false isn't good enough.

• Why are you using a global variable for the directory handle?

• It's so easy to check opendir for errors, it's a very likely candidate for errors. Add a check!

my $Tdir_qfn = "/var/www/campbell/campbell.edu/www/content/2/";
opendir(my $Tdir_dh, $Tdir_qfn)
   or die("Can't read dir \"$Tdir_qfn\": $!\n");

while (defined( my $f = readdir($Tdir_dh) )) {
   print "<li>$f\n";
}

closedir($Tdir_dh);
