Here is some inspiration for you:

#!/bin/bash
nc fe3 6546 -i 1 > /tmp/frontendStatus.out <<EOS
query location
quit
EOS

! tail -2 < /tmp/frontendStatus.out | grep -e "# Playback" > /dev/null

What this shows is how to ask a frontend what it's doing. This
particular script is only interested in the Playback state, but more
options are available:
