tmux

tmux is a terminal multiplexer that allows users to create, access, and control multiple terminals from a single screen. It enables users to detach from a session and reattach later, keeping processes running in the background. This is particularly useful for developers, system administrators, and anyone who frequently works with command-line interfaces and needs to manage multiple tasks or maintain persistent sessions across different machines or network disconnections. The tool is designed for efficiency and productivity in command-line environments. It runs on various Unix-like operating systems, including OpenBSD, FreeBSD, NetBSD, Linux, macOS, and Solaris. Its core functionality revolves around managing windows and panes within a single terminal, offering features like splitting windows, resizing panes, and easily switching between different sessions.
