"pull request": symlinking and restart in PlexConnect_daemon.bash

[ReneV]

I'm not set up to use GitHub but was wondering if you're interested in these two changes to PlexConnect_daemon.bash

- resolve INSTALL_DIR automatically, incl under symlinking [from http://stackoverflow.com/a/246128]

- restart option

 

The first allows for symlinking from whatever startup location your particular system prefers.

#!/bin/bash

sample start stop script

DNAME=“PlexConnect”

PNAME=“PlexConnect_daemon”
Others, w/path resolution from http://stackoverflow.com/a/246128

while [ -h "SOURCE" ]; do
  DIR="( cd -P “$( dirname “SOURCE" )" && pwd )"
  SOURCE="(readlink “$SOURCE”)”

[[ $SOURCE != /* ]] && SOURCE=”$DIR/SOURCE"
done
INSTALL_DIR="( cd -P "$( dirname “SOURCE" )" && pwd )"

{

{PYTHON} {PROGRAM} --pidfile ${PID_FILE}

}
stop_daemon ()

{

kill cat ${PID_FILE}

wait_for_status 1 20 || kill -9 cat ${PID_FILE}

rm -f ${PID_FILE}

}
daemon_status ()

{

if [ -f {PID_FILE} ] && kill -0 `cat {PID_FILE}` > /dev/null 2>&1; then

return

fi

rm -f ${PID_FILE}

return 1

}
wait_for_status ()

{

counter=2
    while [ {counter} -gt 0 ]; do

daemon_status

[ $? -eq $1 ] && return

let counter=counter-1

sleep 1

done

return 1

}
Determine if the network is up by looking for any non-loopback network interfaces.
Currently supports only OSX “Darwin” OS
CheckForNetwork()

{

local test
if [ -z "${NETWORKUP:=}" ]; then
	test=$(ifconfig -a inet 2>/dev/null | sed -n -e '/127.0.0.1/d' -e '/0.0.0.0/d' -e '/inet/p' | wc -l)
	if [ "${test}" -gt 0 ]; then
		NETWORKUP="-YES-"
	else
		NETWORKUP="-NO-"
	fi
fi

}
Determine if the operating system is OSX “darwin”. If so, then delay running the rest of
the script until the network is up. This avoids the binding of PlexConnect to the
loopback address which occurs if the bash script is called from a LaunchDaemon/plist
file at boot time.
if [[ “OSTYPE" == "darwin"* ]]; then
CheckForNetwork
	while [ "{NETWORKUP}” != “-YES-” ]

do

sleep 5

NETWORKUP=

CheckForNetwork

done

fi
Now do what you need to do.
case 1 in
    start)
        if daemon_status; then
            echo {DNAME} is already running

else

echo Starting {DNAME}...
            start_daemon
        fi
        ;;
    stop)
        if daemon_status; then
            echo Stopping {DNAME}…

stop_daemon

else

echo {DNAME} is not running
        fi
        ;;
    status)
        if daemon_status; then
            echo {DNAME} is running

exit 0

else

echo ${DNAME} is not running

exit 1

fi

# Restart the daemon.
