Thank you! I use git already but the piece I was missing was how to integrate it with neocities. Sometimes I only need to upload a robots.txt or changes to the splash page since I keep only a redirect splash page rather than my whole site, so it looks like I can make a script to just upload those few files to neocities when I make updates . thank you again!
Good job. I used Ruby earlier this year to bulk delete image files from my site's root directory: https://bmh.neocities.org/how2/bulk_delete
