Thanks again. I would never have thought of that.
It is getting closer but still not quite there. With my point just after
the defun of shell-command-to-string I did c-x c-e. Then I did c-x c-e
right after (shell-comment-to-string "echo hello"). I got "hello^J" in
my minibuffer but alas not in my file buffer. So, all I need now is the
incantation for a defun which puts the output in the file buffer and not
the minbuffer.
Thanks,
Bill
btw, I got analogous results when I tried the analogous thing
with...
(shell-command "echo Testing")
(save-excursion
(set-buffer "*Shell Command Output*")
(buffer-substring (point-min)
(point-max)))
