Re: question about # of files in a directory

Is there a way to call or maybe get the # of files in a directory? 

The simplest way is to use opendir() and readdir().

  opendir my($dh), $path or die "can't opendir $path: $!";
  my @files = readdir $dh;
  closedir $dh;

Now you have the files from the directory $path in the array @files. The number of elements is the number of files.
