How to Use the Tmux on Linux?
Different usages of the Tmux are explained with examples in the next section. First, we will launch the Tmux using the command:
When the tmux is opened; then users can find the below-mentioned screen:
To apply different shortcut keys, first, we should press the prefix key to enter the command mode, which can be done by pressing the “CTRL+b”:
Now, we will explain different usages of the Tmux with examples.
