FYI, batch rename (with counters and some patterns, but not regex) and Copy as pathname (hold Option) are already Finder features.

  Basic Batch Rename
  Standard ZIP Compression
  Image Format Conversion (right click, "Quick Actions")
    Also removes background (better than GIMP does)
  Path Copying Tools

Got 'em and since perl comes with the OS, this batch rename is my "go to" tool.

  # rename script examples from lwall:

  #       rename 'y/A-Z/a-z/ unless /^Make/' *
  #       rename '$_ .= ".bad"' *.f
  #       rename 'print "$_: "; s/foo/bar/ if <stdin> =~ /^y/i' *

  $operation = shift;
  for (@ARGV)
  {
      $previous = $_;
      eval $operation;
      die $@ if $@;
      if ($previous ne $_)
      {
          if (-f $_)
          {
              warn "$0: $_ already exists\n";
          }

I also use cdto a lot. Put its icon in the finder toolbar and you can cd to the finder's location with one click.
