on debian systems there is a /etc/init.d/skeleton file which is a template you
can use as a starting point. See also man update-rc.d for more infos on how
to setup startup scripts. Don't do it by hand! As the skeleton is quite
complex, for a simple startup action you can use something like this (just be
aware that it may be called several times depending on the runlevel(s) you
choose) :
. /lib/lsb/init-functions
case "$1" in
start)
log_daemon_msg "Doing something"
# do it...
log_action_end_msg 0
;;
esac
You may also have a look at /lib/lsb/init-functions which contains some system
functions often used in startup scripts.
