That's so helpful 👍

Nice and clean - thanks

Good example ... but, what's about the "status" option?

In the default option of "case" I think you have to use $0 instead of $1:
echo "Usage: "$0" {start|stop|restart}"

Thanks, very helpful!

I think that could work if runs only with root/sudo
With localuser that
PIDFILE=/var/run/$NAME.pid
will not work, proper way will be
PIDFILE=/var/run/$NAME/$NAME.pid
/var/run is writable only for root

lovely, thanks!

@alobato
I guess add --make-pidfile like below
start-stop-daemon --start --quiet --make-pidfile --pidfile $PIDFILE --exec $DAEMON -- $DAEMON_OPTS

I couldn't find a way to +1 @fvargasruiz comment, but he's correct so I'm quoting him here:
