Introduction

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.

tmux conform C/S mode, including followed modules:

• server - run tmux in terminal to start a server;
• session - a server can include serveral sessions;
• window - a session can include serveral windows;
• pane - a window can include serveral panes.

Key Bindings

The method of controlling an attached tmux session is via key combinations called 'Prefix' keys.

Configuring ~/.tmux.conf

tmux.conf can be used to set options automatically on start up, much like how .vimrc or init.el are used.

# Example tmux.conf

### General

# Scrollback/History limit
set -g history-limit 2048

# Index Start
set -g base-index 1

# Mouse
set-option -g -q mouse on

# Force reload of config file
unbind r
bind r source-file ~/.tmux.conf

### Keybinds

# Unbind C-b as the default prefix
unbind C-b

# Set new default prefix
set-option -g prefix ` 

# Return to previous window when prefix is pressed twice
bind C-a last-window
bind ` last-window

# Allow swapping C-a and ` using F11/F12
bind F11 set-option -g prefix C-a
bind F12 set-option -g prefix `

# Keybind prefrence
setw -g mode-keys vi
set-option -g status-keys vi

# Moving between panes with vim movement keys
bind h select-pane -L
bind j select-pane -D
bind k select-pane -U
bind l select-pane -R

# Window Cycle/Swap
bind e previous-window
bind f next-window
bind E swap-window -t -1
bind F swap-window -t +1

# Easy split pane commands
bind = split-window -h
bind - split-window -v
unbind '"'
unbind %

# Activate inner-most session (when nesting tmux) to send commands
bind a send-prefix
