tmux

tmux show -g | sed 's/^/set -g /' > ~/.tmux.conf
tmux show-options -g | grep prefix
tmux source-file ~/.tmux.conf
set -g default-terminal "screen-256color

alias tmux='tmux -2'  in .bashrc

prefix ?  #show shortcuts
unbind C-b

set-option -g prefix C-a
bind-key C-a send-prefixa)create window   prefix c
next window prefix n
last window prefix p
prefix number
b)detach session
prefix d/D
tmux ls
tmux kill-session -t number
tmux attach -t number
c)split
horizontally  prefix "
vertically %
move from pane to pane prefix arrow
4)kill current pane
prefix x
5)copy/paste with mouse
shift +mouse
option + mouse (macos)
prefix z maximum pane
6)copy and paste
1. Enter ‘copy mode’ by pressing CTRL+b, [.
2. Use the arrow keys to go to the position from where you want to start copying. Press CTRL+SPACE to start copying.
3. Use arrow keys to go to the end of text you want to copy. Press ALT+w or CTRL+w to copy into Tmux buffer.
4. Press CTRL+b, ] to paste in a possibly different Tmux pane/window.
5. create panel in the current panel
add following lines to ~/.tmux.conf

bind c new-window -c "#{pane_current_path}"
bind '"' split-window -c "#{pane_current_path}"
bind % split-window -h -c "#{pane_current_path}"

1. Add these lines in a file by name ~/.tmux.conf.
   

   bind P paste-buffer
   bind-key -t vi-copy 'v' begin-selection
   bind-key -t vi-copy 'y' copy-selection
   bind-key -t vi-copy 'r' rectangle-toggle
   

   Note that for a newer tmux version (2.4 and above I think, not sure), the last three lines should be replaced with:
   

   bind-key -T copy-mode-vi v send-keys -X begin-selection
   bind-key -T copy-mode-vi y send-keys -X copy-selection
   bind-key -T copy-mode-vi r send-keys -X rectangle-toggle
   

2. Now you can enter copy mode by pressing CTRL+b,[, and then go to start point, press ‘v’ and start copying. After you have selected text you want to copy, you can just press ‘y’ (or the default ‘enter’ key) to copy the text into Tmux’s buffer. This is exactly the commands you would use in Vim to copy text.
3. To paste, press CTRL+b,P. Note that it’s capital ‘p’ (i.e. SHIFT+p). This again is similar to Vim’s shortcut ‘p’ for paste, though not exactly similar.
