A slack clone in 5 lines of bash

Suc is a Simple Unix Chat system that provides core features similar to Slack and Mattermost but with just five lines of code. It leverages SSH, UNIX's access control API, and UNIX's text-based modularity for authentication, access control, encryption, and more. With only 55 lines of code, suc can implement the core features of Mattermost with just 0.005% of the code, making it a lightweight and secure alternative.
