Hello, author here to bring a quick note. I've been using a file event command triggerer "when-changed" (requires watchdog) since long time for my dev environment. As I mostly use macos for development, I wanted to see if a solution would exist without any installations. Turns out, macos already supports file events using launchd (https://stackoverflow.com/a/1516034). I've written a simple Python script to wrap around this idea. As a result, it saved the day with no deps as I was looking to execute a simple bash command only. I hope you enjoy it too! Thank you for checking out.
