Are these files that need renaming? You could open the terminal cd to the directory.

for filename in $(ls *.mp4); do
  if [[ "$filename" =~ some_file_match*.mp4 ]]; then
    modified_filename=
    cp $filename $modified_filename && rm $filename -f
  fi
done

Sonarr is capable of bulk renaming TV shows to follow whatever naming convention you set in the settings. Even if you don’t use it for downloading new media, it does a good job of managing your collection.

Edit: Runs on linux and has a web-based GUI.

perl-rename and a good regex. I'm not joking!

Filebot is awesome!
It's a paid app, but you can use version 4.7.9 for free. However I think it's totally worth the $6 for a year. They also have a Lifetime Universal license if you find yourself using it often.

If your just talking file renaming a short shell or python script lifeless then 20 lines can do it too as long as it is a well defined process. Could even run as a scheduled job with cron, anacron, or at.

Tinymediamanager the paid version is so worth it.

Ages ago I did this with some cli tool that found episode/movie metadata stored in themoviedb or somewhere and just built a shell script around it. I don't remember the name unfortunately. Now I just let Plex manage it and I don't bother.

This looks like it might work though:
