Easy Pane Spitting# Splitting Panesbind \ split-window -hbind - split-window -v

Easy Pane Movement# Movement keys, vim stylebind h select-pane -Lbind j select-pane -Dbind k select-pane -Ubind l select-pane -R

Pane Resizing# Pane resizing, vim stylebind H resize-pane -L 5bind J resize-pane -D 5bind K resize-pane -U 5bind L resize-pane -R 5

Let’s make resizing easier by repeating

# Pane resizing, vim stylebind -r H resize-pane -L 5bind -r J resize-pane -D 5bind -r K resize-pane -U 5bind -r L resize-pane -R 5

resizeprefix L

-r Means you can hit it repeatedly without the prefix

Start at 1# Windows and panes index renumberingset -g base-index 1setw -g pane-base-index 1

Basic UI# Colorsset -g status-fg whiteset -g status-bg black

Window movement# Window Movementbind -r C-h select-window -t :-bind -r C-l select-window -t :+

teamocila tmux “addon”

teamocil 0.4.51.0 was a rewrite, removing features I loved

tmuxinator also exists

$ gem install teamocil -v 0.4.5The version I recommend

$ teamocil -e <name>edit the config

1 session: 2 name: "confoo" 3 clear: true 4 windows: 5 - name: "confoo" 6 layout: even-horizontal 7 options: 8 synchronize-panes: true 9 panes: 10 - cmd: "" 11 - cmd: "top" 12 - name: "redis" 13 panes: 14 - cmd: "redis-server"

let’s see it

Another sample file
