I'm not sure if I understand your problem correctly. # starts a comment
in shell, and $ denotes (among others maybe) a variable name. In that
sense 

#+begin_src bash
$ls
#+end_src

delivers the value of the variable ls. The semantic of $ is not to
execute the command ls as a non-root user. Same goes for #. If you want
to put your own semantics into $ and # it might be better to not use a
bash code block.

If you want to note that some commands in a script needs root privilege,
maybe something like this would do the trick:

#+begin_src bash
ls
su - -c 'fdisk /dev/rdsk/c0d1/p0'
emacs&
#+end_src
