bash function without arguments
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?
bash
