That is, I want readers to read along, and then execute the c= ode as needed. Currently, it never returns (until C-g). It might be related to the issues= discussed last November,=20 http://lists.gnu.org/archive/html/emacs-orgmode/2009-11/msg01166.html I have the latest git version of org mode, and I think I've set comint-prom= pt-regexp correctly. So: I don't want to filter the output, I don't want to collect the results = - just send the commands and go. Looking at ob-sh.el/org-babel-sh-evaluate, I can't figure out what the Righ= t Thing to do is. Appended is a cheap hack that checks for "ignore" as a r= esults string (e.g. #+begin_src sh :session *shell* :results ignore) and se= nds the lines one at a time to the inferior shell buffer. But I suspect th= ere's a more straightforward way to do it. Thoughts?
