1. OK

2. It won't work if you run that command on a PC while trying to update a remote client such as a Firestick - you also need to tell the script the IP address of the remote client ie. Firestick, for example texturecache.py c tvshows @kodi.host=192.168.0.101 (assuming you have a Firestick listening on IP address 192.168.0.101).

3. This will potentially refresh any tvshows that include the characters "Beyond" - obviously it will only work correctly if the .nfo files are present as @qax.nfo.refresh causes it to query the modification timestamp of your .nfo files. And if it does refresh a tvshow (or or episode) then Kodi will need the .nfo files - "refresh" in this context is "delete tv show or episode, and rescan the same").

4. Not something I'd advise as you'll likely regret it in future, but OK

5. Yes, that's what this script is designed to do on your behalf.

6. Yes - your example would cache artwork for any tvshows that includes the name "Batman Beyond". Note that the c command will cache artwork that is not yet already cached, while the C command will forcibly re-cache artwork (remove existing cached artwork then re-cache it - useful if the existing cached artwork is incorrect).

Obviously if you are deleting your source artwork in #5 then using C would be highly inadvisable. Should you ever lose the Textures13 database or Thumbnails folder on one of your clients then you'd obviously be pretty much stuffed if you've already deleted the source artwork.
