bash comments in emacs

How can I set up a shortcut to comment out or uncomment whole regions in 
a bash script? Like C-c C-c for C++ comments. 

Thanks!

C-;

Note that it's C-; also for C++ comments and any other comment. I
don't you where you got that C-c C-c...

What command does that invoke?

On my Emacs system it has always been M-; to comment out. It invokes comment-dwim.

Thanks. Just to be sure, you mean Ctrl followed by a semicolon (;) right? 
Unfortunately didn't work. M-; did though, and that's good enough.

Good question. I looked at my .emacs file and I think C-c C-c comes from 
the dwim thing:

;; Nice trick for commenting/uncommenting regions, using dwim (do what I 
mean)
;;
;;
;; Otherwise, to uncomment use C-u C-c C-c (opposite of C-c C-c to 
comment out)
;; The C-u trick works with latex too. 
;; Highlight region, then M-x comment-region. 
;; To uncomment, highlight, then C-u M-x comment-region.

(if (fboundp 'comment-dwim)
  (add-hook (if (boundp 'c-mode-common-hook)
               'c-mode-common-hook
             'c-mode-hook)
            (lambda ()
              (define-key c-mode-map "\C-c\C-c" 'comment-dwim))))

and similarly for C++, latex and matlab.

I think by default, in C mode, C-c C-c calls comment-region, which I
assumed was what Amadeus was originally after. You could always do
something like

(add-hook 'sh-mode-hook
          (lambda ()
             (define-key sh-mode-map "\C-c\C-c" 'comment-region)))

(pilfering blatantly from the code I just snipped)
