shell-script-mode

Hello !

It's about a problem of fontifying my files in the shell-script-mode.

I use 2 XEmacs programs. One is the version 21.4 (patch 9) on a 
Macintosh computer (Darwin environment, Mac OS 10.2.8, where I can 
change whatever I want) ; the other is the version 21.4 (patch 14) on 
another machine (alpha-dec-osf5.0, where I can NOT change anything 
(it's not mine, I just have the home that I can customize as I want, 
more or less)). They are assumed to be the same.

The problem is the following : on the Mac, when I open my script files, 
XEmacs automatically recognizes that they are shell scripts and 
automatically turns to the major mode 'shell-script' and fontifies also 
all according to my colours set-up. No matters if they are in ksh or 
bash, it works.
On the other machine, it does not work. I have no 'shell-mode-script' 
and still this morning not even a 'ksh-mode'. So it's impossible to 
fontify my files as I would like them to be fontified (they are too big 
to be used without colours). I succeeded this morning to force XEmacs 
to know the 'ksh-mode' : I copy the ksh-mode.el (and .elc) from the 
Mac, into a .xemacs/lisp/ directory I created and my init.el file (or 
.emacs or custom.el ...) calls it with :

(setq load-path (cons (expand-file-name "~/.xemacs/lisp/") load-path))
(require 'ksh-mode)

So, now, when I open XEmacs from the second machine, I can say M-x 
ksh-mode. But still it is not automatic and the colours do not fit to 
what I asked in the preferences. I think it would be better if my major 
mode was 'shell-script-mode' and not 'ksh-mode', but as I don't have it 
on this machine and as I don't find it on the Mac (so that I could copy 
it from the Mac, as for the ksh-mode.el(c)) ...

Please, does anybody have any idea ??? I don't yet understand really 
well the init/custom/.emacs.el syntax, I'm blocked and I absolutely 
need this shell-script mode !
