Tmux is a terminal multiplexer, a tool that allows users to run multiple terminal sessions from a single window. It enables the management of several programs or shell sessions concurrently, with the capability to detach and reattach them without interrupting the processes running in the background.
Tmux stands for Terminal Multiplexer, and it is a highly flexible, command-line-based tool commonly used in Linux, macOS, and other Unix-like systems. Its primary purpose is to enhance productivity for system administrators, developers, and anyone who frequently interacts with the command line. Tmux can split a terminal into panes, run multiple sessions, and allow users to share sessions with others—all within a single interface.
Tmux is especially useful for managing long-running processes or working on remote servers, where detaching a session ensures that processes continue running even if the user disconnects.
.tmux.conf file, allowing users to define key bindings, appearance, and behavior.System administrators often use Tmux to manage servers, ensuring processes like updates, backups, or scripts continue running.
Developers use Tmux for running server instances, monitoring logs, and testing code simultaneously in separate panes.
Sharing sessions makes it a practical tool for teaching, debugging, or collaborating in real time.
Tmux sessions are invaluable for maintaining ongoing work when using unreliable network connections.

bashCopy codeset -g mouse on
bind r source-file ~/.tmux.conf
Automate session creation with a script:
bashCopy codetmux new-session -d -s dev
tmux split-window -h
tmux send-keys 'npm start' C-m
tmux select-pane -t 0
tmux send-keys 'code .' C-m
tmux attach -t dev
Enhance Tmux functionality using plugins such as tmux-resurrect (restores sessions) or tmuxinator (session management).
Enable mouse mode for easier navigation:
bashCopy codeset -g mouse on
Use Tmux’s configuration to optimize for large projects or specific workflows.

You can install Tmux on Linux using your package manager. For example, on Debian or Ubuntu-based systems, use the command: sudo apt install tmux. For other distributions, consult their respective package management tools.
To detach a session, press Ctrl-b d. To reattach a detached session, use the command: tmux attach -t session_name, replacing session_name with your session’s name.
Some basic Tmux commands include:
tmuxtmux new -s session_nameCtrl-b %), Vertical (Ctrl-b ")Ctrl-b and arrow keystmux list-sessionsYes, you can customize Tmux by editing the .tmux.conf file in your home directory. Common customizations include key bindings, appearance settings, and enabling mouse support by adding set -g mouse on to the configuration file.
