Definitly not. It's Common Lisp.

Well extending my solution to more files is easy

(mapc '#(lambda (file) (q-2003-01-14 file) 
          ;; rename the generated file if needed)
        (directory "pattern"))

That's all

Doing that all in Emacs Lisp isn't much more difficult.

For getting a file listing in Common Lisp use directory in Emacs Lisp
it's directory-files. 

But I *strongly* sugggest you post there where you expect an
answer. Is it a shell problem use some .shell group if it's Emacs Lisp
use some emacs Newgroup and if you want Common Lisp post here.
