On a remote machine or on your local machine?

Either. :)

If you setup a source block, you can use TRAMP to actually execute the command in a source block on a remote machine. So:

    #+BEGIN_SRC sh :dir /[email protected]:~/remotedir 
      ls
    #+END_SRC

The above will run ls on "remotemachine.com" and put the results in an output block below it.

Edit: Meant to add that you can do the same with docker. Just use "/docker:dockerId:" as the dir, and it will execute in a docker instance locally. Using multihop addresses, this can get extreme.

Oh, that's very cool. Almost QNX like!

Org mode is one of the few real literate programming tools that I'm aware of, the other one is 'Leo'.

that's it. I'm learning org-mode.

Please do a write-up.

If there are examples you'd like to see written up, I'd be interested in helping out.

I used to try complicated examples, which led to pages such as http://taeric.github.io/Sudoku.html. I'm now much more into writeups such as http://www.howardism.org/Technical/Emacs/literate-devops.htm.... (Note, I did not write the second one.)
