What proc does

It is a command-line tool for finding and controlling running processes on macOS, Linux and Windows. Commands can target a process by its port, PID, name or path. It can print JSON output so scripts and coding agents can read results.

Built for

  • Developers who need to free ports or manage running processes
  • Coding agents and scripts that read JSON output

Key features

  • Finds what is listening on a port
  • Shows why a process was started by walking its parents
  • Finds orphaned processes whose parent has exited
  • JSON output with --json for scripts
  • Preview of changes with --dry-run

Pros
