Linux bash script to provide global shortcut control for MOC or any MPRIS-enabled player.
The script should be placed somewhere in the $PATH (~/bin; /usr/local/bin etc).
Then a few keyboard shortcuts could be added in your WM or via xbindkeys (if used). See help for available actions.
If several players are running at the same time, MOC is always given priority, and then the MPRIS player which was launched the earliest. Each time the script is run, it checks for running players and sends the command to the one that matches the above criterium.
