Perl Deleting Shows
From MythTV Official Wiki
Deleting Shows using Perl
MythTV has bindings for perl that allow you to delete a show based on its filename. The following code can be used in a perl script:
use MythTV; $Myth = new MythTV(); $file = $Myth->new_recording($ARGV[0]); $Myth->backend_command(['FORCE_DELETE_RECORDING', $file->to_string()], '0');
Using a command line of:
./deleteshow.pl 1001_20081015112300.mpg
Would result in the show being deleted.
