Description
Hi HN,I built a small Linux CLI tool called witr (Why Is This Running?).The idea came from a situation most of us have hit: you log into a machine, see a process or port running, and immediately wonder why it exists, who started it, and what is keeping it alive right now.witr traces a process, service, or port back to its origin and responsibility chain and explains it in a way that’s quick to read, especially when you’re debugging under pressure.This is v0.1.0. It’s intentionally small and focused. Feedback, criticism, and edge cases are very welcome.Repo: https://github.com/pranshuparmar/witr

Could you build this?
Yes This is a Linux CLI tool that inspects the /proc filesystem, systemd dbus APIs, and socket statistics to format a trace of parent processes and services.
