tmux

Tmux is an alternative to screen.

s  list sessions
$  name session

c  create window
w  list windows
n  next window
p  previous window
f  find window
,  name window
&  kill window

{  swap current pane with previous pane

%  is vertical split
"  is horizontal

Up-arrow scroll up
Down-arrow scroll down

z  full screen, useful to copy when you have split windows

<  menu to swap, kill, rename, new after/before

Tmux only copy-paste

requires: setw -g mode-keys vi, else in my experience I was not able to paste

• ctrl + b, then [ you're in copy mode (by scrolling).
• Use space bar from your pointer to select.
• Press enter to save into buffer tmux's buffer
• Paste from latest entry into tmux's buffer ctrl + b, then ]

See also related commands:

• list buffers: :list-buffers
• paste: :choose-buffers, then select the string to paste

System/host copy-paste

Similar to Tmux copy-paste, but use y instead of enter to copy into system's buffer. Paste with shift + insert.

In order to copy into system's buffer, you need to bind a key to a command such as xclip as below.

# (optional) if you want `v` like vim to select instead of `space bar`
bind-key -T copy-mode-vi v send-keys -X begin-selection
# paste within xclip (system buffer) by using `y`
bind-key -T copy-mode-vi y send-keys -X copy-pipe-and-cancel 'xclip -sel clip -i'

requires: xclip installed

Resize pane

Example to resize 2 times Up:

:resize-pane -U 2

Note: There also -L for left, -R, -D

Close current command (e.g., freeze ssh)

:respawn-pane -k

Join windows

:join-pane -t <target-window-number>

Notes:

• use w to list windows
• use -t for target or -s for source

Move pane to a new window

:break-pane -dP
