🔍 whyrun v1.0.0 — first stable release

Trace a port / PID / process name / open file back to what started it — one static binary, zero dependencies, zero telemetry.

✨ Highlights

  • whyrun port <PORT> — resolve the process behind a listening TCP/UDP port (IPv4 & IPv6)
  • whyrun pid <PID> — executable, full command line, cwd, user, state, start time, sockets, container ID
  • whyrun name <REGEX> — fuzzy process matching across name / exe / cmdline
  • whyrun file <PATH> — find every process holding a file open (exact /proc/PID/fd matching on Linux)
  • whyrun tree [PID] — whole-machine or subtree process tree with --depth
  • Full parent launch chain ("launched by 1 systemd → … → target") for every match
  • Linux reads /proc directly — no lsof/netstat required; macOS/BSD use ps+lsof; Windows uses CIM + netstat -ano
  • Docker / containerd / Kubernetes container ID detection via cgroup
  • --json on every command + stable exit codes (0 found / 1 not found / 2 usage / 3 internal)
  • Pure Go standard library only, statically linked, ~2 MB binary
