Find mediaserver IP with command line

Last week I need to find the IP of my UPnP mediaserver in a console environment.

I didn’t find a small to get only the IP, so I wrote this small script that uses the GUPnP.

find_upnp_mediaserver_ip.sh

#!/bin/sh

DISCOVER="/usr/bin/gssdp-discover"

check_discover()
{
    if [ ! -f $DISCOVER ]; then
        echo "$DISCOVER not found. Please install gupnp-tools"
        exit 1
    fi
}

find_ip()
{
    $DISCOVER -n 5 --target=urn:schemas-upnp-org:device:MediaServer:1 |
        grep -o -E '([0-9]){1,3}\.([0-9]){1,3}\.([0-9]){1,3}\.([0-9]){1,3}'
    exit 0
}

## main
check_discover
find_ip
