Awesome!

I think this will work for me (since I can have an unspecified number of elements in an array...)

# our $input is user inputted string
# and I only want directory/ names
our @matches = map { -d $_? $_ .="/" : "" } <$input*>;
expand_match || print "\a";

sub expand_match {
  return $input = $matches[0] if(@matches == 1);
  # Get the longest matching string from all elements
  my $match = $matches[0];
  for (@matches) { 
    $match = substr $_, 0, ( $match ^ $_ ) =~ /^\0*/ && $+[0]; 
  }
  return $input = $match if length($match) > length($input);
  return 0;
}
