What is pkll?

Ever needed to kill a process blocking a port but had to juggle lsof, netstat, and kill just to do it? pkll handles it in one command — and shows you exactly what you're about to kill before you do it.

$ pkll 3000

  Process on port 3000
  ─────────────────────────────────────
  Name     node
  PID      48291
  User     yoftahe
  Uptime   1h 23m
  Type     TCP
  Command  node server.js

  Kill this process? [y/N]
