If you’ve ever found yourself juggling multiple terminal windows while working on Linux, you already know how messy things can get. That’s where tmux comes in, a lightweight yet powerful terminal multiplexer that turns a single window into a fully organized workspace. Instead of opening multiple terminals, tmux lets you split one screen into multiple panes, each running its own command. This is especially useful for system administrators, network engineers, and anyone working on labs or servers. Why use tmux? tmux allows you to: Split your terminal into multiple panes Run different commands simultaneously Keep sessions running even after disconnecting (perfect for SSH) Navigate efficiently without leaving your keyboard Getting started: First, install tmux on RedHat: ]$ dnf install tmux -y Launch it with: ]$ tmux You’ll notice nothing fancy at first but the power comes from its shortcuts. Splitting your screen: tmux uses a prefix key (Ctrl + b) followed by commands: Split vertically: Ctrl + b, then % Split horizontally: Ctrl + b, then " To create a 4-pane layout: Split vertically Move to one pane and split horizontally Move to the other side and split again Now you have four independent terminals inside one window. Navigation Switch between panes using: Ctrl + b, then arrow keys This makes it easy to monitor logs in one pane, edit files in another, and run commands in the rest.
