hi

Hi, I'm Rex Roof. I started using screen in the 1990s and switched to tmux in 2015. This is talk is about why you should have a virtual terminal.

what is a virtual terminal?

A window manager for your terminal. A way to manage multiple login/shell sessions in one terminal. Gives you a way to manipulate your terminals and detach and reattach from terminal sessions.
