Hi all,
apparently when the exit code of the last command in a shell code block
is not zero, I do not get the results. This doesn't seem to be
documented in the manual (though I might be missing something). Check
this:
#+begin_src bash :results verbatim
echo hello world
exit 0
#+end_src
and this:
#+begin_src bash :results verbatim
echo hello world
exit 1
#+end_src
How can I tell Org to put the results in the file anyway? My use case
is =diff=, which exists with status 1 if differences are found, and this
is a blog post, so I do not want to pollute the post with an =exit 0= at
the end of the code snippet.
TIA,

Hi there,
This is the expected behavior, implemented in `org-babel-eval`. (By the
way, the docline of `org-babel-sh-evaluate` seems to talk about a different
function.)
As a workaround, you could define a new shell that always returns 0:
(push "0bash" org-babel-shell-names)
(org-babel-shell-initialize)
(defun org-babel-execute:0bash (body params)
"Execute a block of bash commands with Babel, returning 0."
(let ((shell-file-name "bash"))
(org-babel-execute:shell (concat "trap 'exit 0' EXIT\n" body) params)))
—This is called 0bash because there are special treatments if the shell
name ends with "bash", see `org-babel--variable-assignments:bash`.
Cheers,
M.
