I wouldn't be surprised if it is easy to automate but I don't code. titles used to be "Episode # [title]" and are now "[title] (E#)" for regular and "Premium Episode # [title]" and are now "[title] (Premium E#)" for the patreon feed.
e.g. "American Exorcists feat Sam Kestenbaum (E292).mp3" vs "Episode 258 Pilled in the Peak District (Part1).mp3"
It doesn't take that long to "fix", just my brain won't let me just pop the numbers on the front and let it go, gotta paste Episode or Premium Episode to the front cause all the others are like that and then delete the end numbers XD. Brains are funny sometimes.
Holy heck, I wrote a long post basically saying "Thank you, but sorry to say I am not clever enough" cause I tried cmd, powershell, installing and then running python from the folder which gave me a terminal sorta deal, and a .bat.
but, then it occurred to me to try .py (had to google "what is .bat but for python" ) and presto you did the thing, well done. It worked and thank you. I, entirely undeservedly, feel like a genius. XD
I appreciate your effort bud and, tangentially, you have now seen an example of why many people "can't" use Linux. I don't even know what "run this" means, even if you do all the work I don't know the literal first thing, took me quite a lot of thought to get there lol.
P.S. I won't be surprised in the least if a text file renamed to .py wasn't even the intended execution and I missed something obvious. I am not tech savvy. I am child willing to push buttons until something happens.
