|
Removes locally thumbnails for previews.
|
|
|
|
The --days option specifies how old preview cards have to be before
|
|
they are removed. It defaults to 180 days.
|
|
|
|
With the --background option, instead of deleting the files sequentially,
|
|
they will be queued into Sidekiq and the command will exit as soon as
|
|
possible. In Sidekiq they will be processed with higher concurrency, but
|
|
it may impact other operations of the Mastodon server, and it may overload
|
|
the underlying file storage.
|
|
|
|
With the --dry-run option, no work will be done.
|
|
|
|
With the --verbose option, when preview cards are processed sequentially in the
|
|
foreground, the IDs of the preview cards will be printed.
|
|
|
|
With the --link option, delete only link-type preview cards.
