This document introduces "ash", a shell that allows controlling multiple devices with a single interface. Ash uses a text-based command language to send commands over a network to remotely control devices installed with the ash application. The architecture includes an evaluator that parses commands, a user interface, and device controllers. Commands can register functions and callbacks. The code is structured as lists, and ash supports interfaces from Android, Ubuntu, OSX, and Windows.
