Tmux
Tmux is a terminal multiplexer that allows users to create, manage, and switch between multiple terminal sessions within a single window. It enables persistent sessions that survive disconnections, supports splitting panes horizontally and vertically, and facilitates efficient workflow management for command-line tasks. It is widely used by developers, system administrators, and power users to enhance productivity in terminal environments.
Developers should learn Tmux when working extensively in terminal-based environments, such as remote server administration, software development, or data processing, to manage multiple tasks without opening numerous terminal windows. It is particularly useful for maintaining long-running processes, organizing workflows with session persistence, and collaborating via shared sessions, making it essential for DevOps, backend development, and system operations.
