Hi,

Is there a way to execute all the org-mode code blocks in a file, and
send the output to stdout?

For example, I have the following org file:

=== BEGIN ===

* Greeting

#+BEGIN_SRC sh :results output
  echo "Hello $USER! Today is `date`"
#+END_SRC

* Current directory

#+BEGIN_SRC sh :results output
  pwd
#+END_SRC

=== END ===

I could go to each code block, and type C-c C-c to produce an output.
But, I just want to be able to execute the entire file, and produce
one single output.

Is this possible?
