tmux cheatsheet:

Source: git clone

start new:


start new with session name:

tmux new -s myname


tmux a  #  (or at, or attach)

attach to named:

tmux a -t myname

list sessions:

tmux ls

kill session:

tmux kill-session -t myname

Kill all the tmux sessions:

tmux ls | grep : | cut -d. -f1 | \
    awk '{print substr($1, 0, length($1)-1)}' | xargs kill

In tmux, hit the prefix ctrl+b (my modified prefix is ctrl+a) and then:

## Sessions

:new<CR> new session s list sessions $ name session

## Windows (tabs)

c new window w list windows f find window , name window & kill window

## Panes (splits)

% vertical split ” horizontal split

o swap panes q show pane numbers x kill pane + break pane into window (e.g. to select text by mouse to copy) - restore pane from window ⍽ space - toggle between layouts <prefix> q (Show pane numbers, when the numbers show up type the key to goto that pane) <prefix> { (Move the current pane left) <prefix> } (Move the current pane right) <prefix> z toggle pane zoom

## Sync Panes

You can do this by switching to the appropriate window, typing your Tmux prefix (commonly Ctrl-B or Ctrl-A) and then a colon to bring up a Tmux command line, and typing:

:setw synchronize-panes

You can optionally add on or off to specify which state you want; otherwise the option is simply toggled. This option is specific to one window, so it won’t change the way your other sessions or windows operate. When you’re done, toggle it off again by repeating the command. [tip source](

## Resizing Panes

You can also resize panes if you don’t like the layout defaults. I personally rarely need to do this, though it’s handy to know how. Here is the basic syntax to resize panes:

PREFIX : resize-pane (By default it resizes the current pane down)
PREFIX : resize-pane -U (Resizes the current pane upward)
PREFIX : resize-pane -L (Resizes the current pane left)
PREFIX : resize-pane -R (Resizes the current pane right)
PREFIX : resize-pane 20 (Resizes the current pane down by 20 cells)
PREFIX : resize-pane -U 20 (Resizes the current pane upward by 20 cells)
PREFIX : resize-pane -L 20 (Resizes the current pane left by 20 cells)
PREFIX : resize-pane -R 20 (Resizes the current pane right by 20 cells)
PREFIX : resize-pane -t 2 20 (Resizes the pane with the id of 2 down by
20 cells)
PREFIX : resize-pane -t -L 20 (Resizes the pane with the id of 2 left
by 20 cells)

## Copy mode:

Pressing PREFIX [ places us in Copy mode. We can then use our movement keys to move our cursor around the screen. By default, the arrow keys work. we set our configuration file to use Vim keys for moving between windows and resizing panes so we wouldn’t have to take our hands off the home row. tmux has a vi mode for working with the buffer as well. To enable it, add this line to .tmux.conf:

setw -g mode-keys vi

With this option set, we can use h, j, k, and l to move around our buffer.

To get out of Copy mode, we just press the ENTER key. Moving around one character at a time isn’t very efficient. Since we enabled vi mode, we can also use some other visible shortcuts to move around the buffer.

For example, we can use “w” to jump to the next word and “b” to jump back one word. And we can use “f”, followed by any character, to jump to that character on the same line, and “F” to jump backwards on the line.
