I asked this question in a 2002 post in the thread describing it and
previous response.
https://groups.google.com/group/gnu.emacs.help/browse_thread/thread/a556b6d959c4a84d/
Has there been any improvements in the last 10 years?

Apparently not... your question is still as ill-specified as it was 10
years ago.

You have to write some emacs lisp.
As someone already said, use call-process.
This calls synchronously ls with the -l and -a options:
(call-process "ls" nil nil nil "-l" "-a")
If you want the return value to be the program output you can use
shell-command-to-string.
You can wrap this line in a function and put it in your .emacs like this:
(defun my-function ()
(interactive)
(call-process "ls" nil nil nil "-l" "-a"))
You can then bind it to a key like this (still in .emacs):
(global-set-key (kbd "<f9>") 'my-function)

It's really not difficult, you should read what people say in this thread.
If you have a previous experience in programming and want a short
introduction to emacs lisp I recommend you Xah Lee's tutorials :

Thanks for the great reply. Your illustrative example was the thing in
need.
