[Orgmode] Babel & sh & Windows

[Srinivas]

Hi

I am trying to learn how to use Babel on a Windows system and need some help.

I would like to produce the directory tree for a given directory (/bin in this 
example).

I tried the following:

#+srcname: directory-tree
#+BEGIN_SRC sh :dir /bin :results output org replace :exports results
tree
#+END_SRC

The output is as given below:

#+results: directory-tree
c:\bin>More? 

My org-babel-sh-command setting is:

(setq org-babel-sh-command "cmd /k")

What do I need to do see some output in the #+results section?

Thanks in advance for you help.
