Usage:
$0 [options]
Deletes recording files and metadata for all recordings in the Deleted
recording group.
options:
--force
Delete the recording metadata even if the file does not exist. Note that
this option should only be used when all storage is connected to and file
systems are mounted on all your backends. Otherwise, forcing deletion of the
metadata may leave orphaned recording files on unconnected file systems.
This option is primarily useful for deleting metadata for a large number of
recordings after losing a file system or otherwise losing many recording
files. Rather than deleting them one by one using mythfrontend and having to
confirm deletion of each recording when the file is not found, you may add a
bunch of recordings to a playlist, then choose MENU|Playlist Options|Change
Recording Group and add the recordings to the Deleted recording group (create
a new group if necessary--its name /must/ be Deleted and is case-sensitive).
Finally, run this script with the --force option. Note that if you have
enabled the setting, "Auto Expire Instead of Delete Recording," this process
will delete all the recordings you just put into the Deleted recording group
and any others that were in there from normal recording deletion.
