My tmux configuration

Tmux

Tmux is a terminal multiplexer that allows users to switch between several programs in one terminal window. It also enables users to detach from a session and continue working on it later. Tmux is highly configurable, making it a popular choice for developers and system administrators.

Setup

Add the below content in your ~/.tmux.conf

vi ~/.tmux.conf

set-option -sa terminal-overrides ",xterm*:Tc"
set -g mouse on

#unbind C-b
#set -g prefix C-Space
#bind C-Space send-prefix

# Vim style pane selection
bind h select-pane -L
bind j select-pane -D
bind k select-pane -U
bind l select-pane -R

# Start windows and panes at 1, not 0
set -g base-index 1
set -g pane-base-index 1
set-window-option -g pane-base-index 1
set-option -g renumber-windows on

# Use Alt-arrow keys without prefix key to switch panes
bind -n M-Left select-pane -L
bind -n M-Right select-pane -R
bind -n M-Up select-pane -U
bind -n M-Down select-pane -D
