Hi this is not strictly an org-babel question - but here is it anyway. If I have an sh code block as follow #+begin_src sh TXT="Hello World" echo $TXT #+end_src and enter it with C-c ' --- is there a way of piping single lines, regions, the whole block to a shell, similar to the functionality provided by ESS and R?
