Thanks! As I said, I am a shell dummy. :-)

Ah! And it works with eshell. I am saved.

I was rather looking for something more formal, preferably with a CF
grammar. The "Shell Command Language Index" looks like what I had in
my mind, though. But never mind. Now that I know how to deal with the
simple loops that I need, I am not so keen anymore on implementing sh
syntax.

Thanks again.

This possibility to mix Lisp and shell scripting is way cool. I could
get used to it:

[~] $ mkdir test; cd test
[test] $ touch alpha.test beta.test gamma.test
[test] $ for f in **/*(.) { if (string-match "\\(.*\\)\\.test$" f) { mv $f 
(match-string 1 f) }}
[test] $ ls
alpha  beta  gamma
