very simple shell script to get nowplaying from cmus and show in tmux status bar

append_to_.tmux.conf

# Stick this in your .tmux.conf somewhere
# This will override your current date setting if you have one though
# So modify to show other things I guess? This was for me really.

set -g status-right "#(nowplaying.sh) | #[bold]%d %b#[nobold] | %H:%M "
set -g status-right-length 120
set -g status-left-length 80
set -g status-interval 2 # Update bar regularly even without focus

nowplaying.sh

#!/bin/bash

# put this in a PATH'd folder. 
# I recommend ~/.local/bin

if pgrep -x "cmus" > /dev/null # is cmus running
then
    START=$(cmus-remote -C status | grep "tag\ title" | head -n 1 | cut -d ' ' -f 3-)
    END=$(cmus-remote -C status | grep "tag\ artist" | head -n 1 | cut -d ' ' -f 3-)
    PLAYING=${START:0:60}" - "${END:0:40}
else
    echo "cmus off"
fi
echo $PLAYING
