I use the following within a shell script:

--8<---------------cut here---------------start------------->8---
DIARY=${HOME}/git/notes/diary
emacs -Q --batch --debug-init \
    --directory=${HOME}/s/emacs --directory=/usr/share/emacs/site-lisp/auctex \
    --load=esf-org.el --visit=${DIARY}.org --eval='(org-export-icalendar-this-file)'
scp ${DIARY}.ics SOMEWHERE_ON_THE_INTERNET
--8<---------------cut here---------------end--------------->8---

I have all relevant settings for org in the file esf-org.el and,
because that file makes use of some auctex variables/functions, I have
to specify a load path for auctex.  The debug-init is not necessary
but I just never got around to deleting it...

I am on Debian Linux (testing/unstable) with emacs 23.2.x and
up-to-date org.

HTH,
