Properly handles passing a Spotify URI to a running instance of spotify via DBUS

better-spotify-linux-launcher.sh

#!/bin/bash
# check if spotify is already running and if so just pass the uri in
if pgrep -f "Spotify/[0-9].[0-9].[0-9]" > /dev/null
then
    busline=busline=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.OpenUri $1
    echo "Spotify is already running"
    echo "Sending ${busline} to dbus"
    if command -v qdbus &> /dev/null
    then
        qdbus $busline
        exit
    fi
    if command -v dbus-send &> /dev/null
    then
        dbus-send $busline
        exit
    fi
    echo "No bus dispatcher found."
# otherwise launch spotify
else
    spotify $1 &>/dev/null &
fi
