Hi everyone,

Quick follow up about this: following Eric's suggestion, I came up with the
following block, which cleans up all the cruft from the output of the
=script= command and produces a nicely formatted session transcript:

#+NAME: cleanup
#+BEGIN_SRC emacs-lisp :var data="" :results value :exports none
  (replace-regexp-in-string
   "\\$ exit\\(.\\|\n\\)*$" ""
   (replace-regexp-in-string
    "^bash-.*\\$" "$"
    (replace-regexp-in-string
     "\\(\\(.\\|\n\\)*?\\)\\$\\(.\\|\n\\)*\\'" ""
     (replace-regexp-in-string "
" "" data) nil nil 1)))
#+END_SRC

(I am not happy with the regexp nesting and repetition above, I am not an
expert yet in emacs-lisp regex facilities. Suggestions appreciated for how
to simplify it).

This produces exactly the result I need:

#+begin_src sh :exports output :results output :wrap "src console" :post
cleanup(data=*this*)
script <<EOF
echo hi
echo bye
EOF
#+end_src

#+RESULTS:
#+begin_src console
$ echo hi
hi
$ echo bye
bye
#+end_src

Thanks Eric!

--Diego
