tmux의 위대함

2018/08/23

tmux를 왜 이제야 알게 됐는지 안타까울 뿐이다. 내가 고민하던 수없이 많은 기능이 이미 구현되어 있다. 윈도우에서 쓰지 못하는게 아쉬울 뿐.

많은 자료가 이미 있기에 여기에서 다시 언급할 필요는 없을 것 같다.

Nvim-R을 쓰면 vim에서 tmux로 분할된 화면 속의 R로 커맨드를 넘기는 작업도 가능하다.

R and vim in tmux

아래는 https://gist.github.com/MohamedAlaa/2961058에서 가져온 cheatsheet을 복사해 놓았다.

tmux shortcuts & cheatsheet

start new:

tmux

start new with session name:

tmux new -s myname

attach:

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  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

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.
