In addition babel should also not ignore stderr on exit status 0, see my example 2) with GNU/Linux's strace in a lengthy post about my thoughts and workarounds for stdout, stderr and exit status with babel. It contains a complete set of the different cases as I see them: http://thread.gmane.org/gmane.emacs.orgmode/45828/focus=45881 Michael

All things considered, there may be room for an argument that Babel shouldn't ignore the data from STDOUT on non-zero exit or have an option to ignore the return code for cases like this.

At least the return status is zero. But I agree with you, a colon is better here. This is my first use of a `:' btw. I never had case before. -- Thanks, Oliver

The exit code is not zero since diff found differences, so Babel assumes the script produced an error. Try this instead when you don't know what the return code of the last command will be or if you know that it isn't zero even when no error occured: #+BEGIN_SRC sh :exports results :results output diff testdiff.txt.orig testdiff.txt : #+END_SRC > Is this this a bug? I don't think so, although Babel could give a more enlightening message about why it didn't evaluate STDOUT. It gives this on your original example: Babel evaluation exited with code 1 Code block produced no output. Regards, Achim.
