I'm not sure I undersand, why you would want to use the shell to specify
a date. Could you please explain? Are you looking for a particular date
format?

The example below, taken from the org documentation produces the current
date when exported to BEAMER.

#+TITLE: Example Presentation
#+AUTHOR: Carsten Dominik
#+OPTIONS: H:2 toc:t num:t
#+LATEX_CLASS: beamer
#+LATEX_CLASS_OPTIONS: [presentation]
#+BEAMER_THEME: Madrid
#+COLUMNS: %45ITEM %10BEAMER_ENV(Env) %10BEAMER_ACT(Act) %4BEAMER_COL(Col)

* This is the first structural section

** Frame 1
