tmux
tmux stands for Terminal Multiplexer. When using Linux in the terminal, there can be inconvenience when sessions are disconnected, causing processes in progress to be interrupted or work to be lost. tmux addresses such inconveniences. Additionally, it provides features like window splitting and session sharing, making it a useful tool for a more efficient Linux experience.
tmux Installation
For Debian-based systems, tmux can be installed using the following command:
1
| $ sudo apt-get install -y tmux
|
tmux Terminology
Before diving into the usage and commands, let’s clarify some terminology used in tmux:
- session: The execution unit created through tmux. Multiple sessions can be created, and each session can be attached/detached. It’s important to note that detaching doesn’t interrupt the work; it continues to run in the background.
- window: Sessions consist of multiple windows, which can be used like tabs within a session.
- pane: Within a window, the screen can be divided, and each division is called a pane.
tmux Session Commands
Session Creation Commands
To create a session, simply use the command above. By default, sessions are named starting from 0. If you want to specify a session name, you can use the -s option as shown below:
1
2
| $ tmux new -s <session-name>
$ tmux new-session -s <session-name>
|
Session Attach/Detach
Upon session creation, you automatically enter that session. To detach from a session, use the following command:
1
2
| # Detach from the session
[Ctrl] + b, d
|
Press [Ctrl] and b simultaneously, then quickly press d. To reattach to the session, use the following command:
1
2
| # Attach to the session
tmux attach -t <session-number-or-name>
|
List Sessions

End Session
As mentioned earlier, detaching doesn’t make the session disappear; it continues to run in the background. If you want to end a session, use the following commands:
1

3
| # End within the session
# -> Executed in the last window, last pane
$ exit
