bash function without arguments












0















I am analyzing the following script (init script for ptpd2 deamon):



#!/bin/sh

#

# Start ptpd2

#



case "$1" in

  start)

        printf "Starting ptpd2: "

        start-stop-daemon -S -q -x /usr/sbin/ptpd2 -- -g -i eth0 -s  

        if [ $? != 0 ]; then

                echo "FAILED"

                exit 1

        else

                echo "OK"

        fi

        ;;

  stop)

        printf "Stopping ptpd2: "

        start-stop-daemon -K -q -x /usr/sbin/ptpd2

        echo "OK"

        ;;

  restart|reload)

        ;;

  *)

        echo "Usage: $0 {start|stop|restart}"

        exit 1

esac



exit $?


What does start), stop) mean? What kind of constraction is this? A function without arguments maybe?
