Bash script to remove Tdarr video source files

[FunkyBuddha]

I was able to improve Tdarr's performance by at least 2x. I did three things. First, I used a RAM drive for the cache. Second, I created a separate output folder. Third, I decoupled the delete function from the Tdarr flow to a script. You can run this ad hoc or scheduled.

Methodology:

• Run the script and parm in the original folder
  • i.e. del_tdarr_orig.sh "/path/to/original_files
• Create a list of all transcoded files
• Use list to find and delete matching original video files
• After the script runs, you can move the content of output folder to the original folder
