Proc

Proc is a semantic CLI tool for process management that finds and controls processes by port, PID, name, or path.

Proc is a semantic CLI tool for process management designed for macOS, Linux, and Windows. It allows users to find what is running on a port, inspect why it is there, and stop it using straightforward commands. Users can target processes by port, process ID, name, full command line, file, or folder. It supports nineteen commands that handle tasks like finding, changing, and watching processes, with features like JSON output for scripts and dry runs for safety. It runs on macOS, Linux, and Windows, and is available on npm, cargo, Scoop, Nix, and Docker.
