Software :: Possible To Run Startup Script Only (not On Shutdown)?

I'm trying (& failing) to write a script in /etc/init.d that only operates on boot up but NOT on shutdown. The program I want to run does not accept any parameters. This works

Code:
#!/bin/bash
test -f /var/www/html/moveit || exit 0
. /var/www/html/moveit
exit 0
but on shutdown and startup.

This doesn't
Code:
#!/bin/bash
test -f /var/www/html/moveit || exit 0
case "$1"
start)
. /var/www/html/moveit
;; top)
;; *)
esac
exit 0
either at startup or shutdown.
