A script to scan through mp3s on my synology ds410 NAS and add any missing stuff to the index. Amazing it doesn't do this by default O_O

reindex synology music

#!/usr/bin/env python

	res = check_output("synoindex -g \"{}\" -t music".format(f), shell=True)
	if re.match(missing_re, res):

		check_output("synoindex -a \"{}\"".format(f), shell=True)
