A script to populate an MPC playlist with BBC radio stream URLs. Run it as a cron every two hours or so.

radio.sh

#!/bin/bash

# Script to generate an mpc playlist containing up-to-date BBC stream
# locations.  This can be run every hour or so as a cronjob to keep
# the non-static BBC streams working.  My version differs from the
# ones I've seen online in that each stream is added to a single
# playlist, rather than individual playlist files. This makes it
# easier to use with MPoD and via command line with "mpc play 4" for
# Radio 4.

# The cronjob can be set up using crontab -e:

# 00 */2 * * * /home/pi/scripts/radio.sh >> /tmp/radio.log

# This runs at the top of the hour every two hours, with the output going to a tmp file to check things are working
