thanks for testing!

That's what I'd like to get as well.  I tried with emacs -Q with no
success.  Seems the sh block is not executed by my bash.

After more thoughts on this my guess is that it has to do with dash
being the default shell in debian.

#+begin_src sh :shebang "#!/bin/bash" :tangle test.sh
  echo $_
  ls -l /bin/sh
#+end_src

#+RESULTS:
| /bin/sh    |   |      |      |   |     |    |       |         |    |      |
| lrwxrwxrwx | 1 | root | root | 4 | Sep | 27 | 14:23 | /bin/sh | -> | dash |

How can I get this to be /bin/bash?  Preferably from within org mode,
but I am grateful for any hint.

(Somehow this question seems familiar to me...)

My setup:

I am on Debian testing with
GNU Emacs 24.0.93.1 (x86_64-pc-linux-gnu, GTK+ Version 3.2.3) of
2012-02-16 on zelenka, modified by Debian
Org-mode version 7.8.03, pulled last week
  (how do I get the release info as well?)

Regards,
Andreas
