Some Basic Commands of tmux

Other than the commands that you enter in the Linux terminal, there are some basic commands associated with tmux as well that you can use to control and configure tmux.

To control tmux, you need to press “Ctrl+B” every time you are going to enter a tmux command. Some of the most common commands that you need to know about while using tmux are the following:

If you want to start a new unnamed tmux session, type the following in the terminal window.

Upon executing this command, the screen should change and you should see a status bar at the bottom of your screen. In the bottom left corner, you should see the screen number and the name of the window, as shown in the following image:

You can also start a new named tmux session. For that, type the following command in the terminal:

You can split the panes you have created as well. Without splitting, the different panes are working in the background and you can see only one pane at a time. You can split panes both vertically and horizontally.

Press “ Ctrl+b+” ” to split the pane horizontally

Press “ Ctrl+b+% “ to split the pane vertically

As you can create multiple panes, there is the provision of moving between those panes as well. Every pane is numbered by tmux. To move to the desired pane, you need to press “Ctrl+b+q”. This should display the list of the number of panes available. To move to a specific pane, press the number of the pane.

There is also the provision of zooming into a pane to have a better look at something you can’t figure out. You can do this by pressing “Ctrl+b+:” and typing “resize-pane -z”.

One of the best features of tmux is that you can go back to the normal command terminal and tmux will continue running in the background. You can detach yourself from the current working session by entering the following command:

If you want to go back to working on the session, enter the following command:

As you can see in the image, we are back where we left off.
