This.

Why in the hell would anyone want to kill random processes that open a port in the tange 2000-6000? And why is this need so pressing as to require a full blown monitor integrated in a task bar?

Without context, this sounds like a complete random silly project that makes no sense and serves no purpose at all.

Without context, it sounds like something someone vibe-coded and git push-ed up to the internet. Which is fine, but it's just unusually precise and verbose for something that would end up being a shell alias for most developers.
