tmux is a terminal multiplexer for Unix-like operating systems. It allows multiple terminal sessions to be accessed simultaneously in a single window. It is useful for running more than one command-line program at the same time. It can also be used to detach processes from their controlling terminals, allowing SSH sessions to remain active without being visible.
Contents
Cheatsheet
Session Management
tmux ls (or tmux list-sessions) tmux new -s session-name Ctrl-b d Detach from session tmux attach -t [session name] tmux kill-session -t session-name
Ctrl-b c Create new window Ctrl-b d Detach current client Ctrl-b l Move to previously selected window Ctrl-b n Move to the next window Ctrl-b p Move to the previous window Ctrl-b & Kill the current window Ctrl-b , Rename the current window Ctrl-b q Show pane numbers (used to switch between panes) Ctrl-b o Switch to the next pane Ctrl-b ? List all keybindings
Moving between windows
Ctrl-b n (Move to the next window) Ctrl-b p (Move to the previous window) Ctrl-b l (Move to the previously selected window) Ctrl-b w (List all windows / window numbers) Ctrl-b window number (Move to the specified window number, the default bindings are from 0 -- 9)
Tiling commands
Ctrl-b % (Split the window vertically)
Ctrl-b " (Split window horizontally)
Ctrl-b o (Goto next pane)
Ctrl-b ARROW KEYS (Move in pane)
Ctrl-b q (Show pane numbers, when the numbers show up type the key to go to that pane)
Ctrl-b { (Move the current pane left)
Ctrl-b } (Move the current pane right)
Make a pane its own window
Ctrl-b : "break-pane"
Usage
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:
List all shortcuts
to see all the shortcuts keys in tmux simply use the `bind-key ?` in my case that would be `CTRL-B ?`
Sessions
:new<CR> new session s list sessions $ name session
Windows (tabs)
c create window w list windows n next window p previous window 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](http://blog.sanctum.geek.nz/sync-tmux-panes/)
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 -D (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 -D 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.
