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.
