Tvheadend

Hello,

I would like to share with you my solution for auto deleting expired recordings:

All items of a "DVR AutoRec Entry" have a field called "Retention". From my understanding, this is the time in days after the recording is deleted from the TVheadend "finished Recordings" list. The recording is not shown in a frontend (like Kodi) anymore, but the actual file on the harddisk is not deleted. I have not found an official solution for deleting the recorded files after the retention time automatically.

So I have written a small shell script which does the job, at least for my setup. I would like to mention that I am not an expert in programming by any means, so the script probably has some shortcomings. Please use at you own risk. I'm not responsible for any accidentally deleted files. For testing purposes I would recommend to comment out the line "while read line; do rm "$line" ;done < $MyFile4", where the actual deletion happens.

The script is run by a cron job at my setup and sends the list of the deleted files by email.

Please feel free to comment and improve the attached script, since there may be cases of interest not being included at the moment.

Cheers, Thomas
