6. prefix = CTRL + b This is the default prefix It’s run before every command prefix d This means type ‘CTRL + b’ and then type ‘d’.
7. prefix d Detaches from the current tmux session In other words, it exits tmux
8. $ tmux ls See sessions running
9. $ tmux attach reattaches to the last tmux session you were attached to

15. set renumber-windows Automatically renumber windows on closing Will get to commands later
16. prefix # ‘prefix 1’ takes you to window/tab #1
17. prefix w provides a list of windows available ‘j’ and ‘k’ to scroll the selections
18. prefix % That’s not 5, but ‘%’, which means prefix SHIFT+5 This splits the pane in half
19. prefix “ split horizontally
20. prefix x kills the active pane In the lower portion of tmux, you’ll see it ask you: kill pane 2? (y/n) type ‘y’
21. prefix o switch between panes

30. demo 3
31. Configuration $ touch ~/.tmux.conf
32. CTRL + B is awkward # Prefix Config set -g prefix C-a unbind C-b # C-a x2 to send C-a to bash bind C-a send-prefix
33. prefix = CTRL + a Remap CAPS LOCK to CTRL.
34. Make it responsive # Changing the default delay set -sg escape-time 0
35. Easy config changes # Easy config changes bind r source-file ~/.tmux.conf \; display "Reloaded!"
36. Easy Pane Spitting # Splitting Panes bind \ split-window -h bind - split-window -v
37. Easy Pane Movement # Movement keys, vim style bind h select-pane -L bind j select-pane -D bind k select-pane -U bind l select-pane -R
38. move one pane left prefix h
39. Pane Resizing # Pane resizing, vim style bind H resize-pane -L 5 bind J resize-pane -D 5 bind K resize-pane -U 5 bind L resize-pane -R 5
40. Let’s make resizing easier by repeating # Pane resizing, vim style bind -r H resize-pane -L 5 bind -r J resize-pane -D 5 bind -r K resize-pane -U 5 bind -r L resize-pane -R 5
41. resize prefix L -r Means you can hit it repeatedly without the prefix
42. Start at 1 # Windows and panes index renumbering set -g base-index 1 setw -g pane-base-index 1
43. Basic UI # Colors set -g status-fg white set -g status-bg black
44. Window movement # Window Movement bind -r C-h select-window -t :- bind -r C-l select-window -t :+
45. or... prefix w
46. or... prefix # #: 0-9

48. # Mac Terminal Support set -g default-terminal "xterm-256color" # Prefix set -g prefix C-a unbind C-b # Start number at 1 set -g base-index 1 setw -g pane-base-index 1 # Faster command sequences by removing escape time set -s escape-time 0 # Rebind set -g prefix C-a bind C-a send-prefix unbind C-b # Move around panes bind h select-pane -L bind j select-pane -D bind k select-pane -U bind l select-pane -R # Splitting Panes bind \ split-window -h bind - split-window -v bind -r C-h select-window -t :- bind -r C-l select-window -t :+ # Allow us to resize panes bind -r H resize-pane -L 5 bind -r J resize-pane -D 5 bind -r K resize-pane -U 5 bind -r L resize-pane -R 5
