Tmux Moment

tmux is a terminal multiplexer, it enables a number of terminals to be created, accessed, and controlled from a single screen. tmux may be detached from a screen and continue running in the background, then later reattached.

The Basics

First we must execute the command tmux, within it we can perform different actions, for these actions we must send commands to tmux, in my case I will use the combination ctrl + b which is the configuration by default after installation:

Description Command
Split terminal horizontally ctrl + b + "
Split terminal vertically ctrl + b + %
Switch to left panel ctrl + b + keys left
Switch to right panel ctrl + b + keys right
Switch to panel up ctrl + b + keys up
Switch to panel down ctrl + b + keys down
See terminal number ctrl + b + q
Jump from one panel to another ctrl + b + o
Close current panel ctrl + b + x
Close the current window ctrl + b + &
Cycle through panel layouts ctrl + b + space
Close current panel ctrl + b + x
Help tmux ctrl + b + ?
List all sessions tmux ls
Version tmux -V
