perldoc -f readdir

      readdir DIRHANDLE
              Returns the next directory entry for a directory opened by
"opendir".  If used in list context, returns all the rest of the entries
              in the directory.  If there are no more entries, returns an
undefined value in scalar context or a null list in list context.

              *If you’re planning to filetest the return values out of a
"readdir", you’d better prepend the directory in question.*  Otherwise,
              because we didn’t "chdir" there, it would have been testing
the wrong file.

                  opendir(DIR, $some_dir) ││ die "can’t opendir $some_dir:
$!";
                  @dots = grep { /^\./ && -f "$some_dir/$_" } readdir(DIR);
                  closedir DIR;
