#!/bin/sh

name=$1
cmd=$2

if [ -z "${name}" -o -z "${cmd}" ]; then
	echo ${0##*/} service_name command
	exit 3
fi

. /etc/rc.subr

load_rc_config ${name}

for dir in /etc/rc.d ${local_startup}; do
	if [ -r "${dir}/${name}" ]; then	
		run_rc_script "${dir}/${name}" ${cmd}
		exit 0
	fi

	if [ -r "${dir}/${name}.sh" ]; then	
		run_rc_script "${dir}/${name}.sh" ${cmd}
		exit 0
	fi	
done

echo "service '${name}' not found"
exit 2


Most useful with shell completion.
