[O] org babel execute shell in sh?

[Panruo Wu]

Dear list,

#+begin_src sh 

for np in {1..32}

do

    echo $np

done

#+end_src

when executing, the output only shows

{1..32}

which is clearly not I want..

After some investigation, I found that orgmode

uses "sh" that cannot understand the for loop above.

My question is, how can I suggest orgmode to use

"bash" to execute shell script?

I tried :shebang #!/bin/bash but it does not work

Thanks,

robb
