tmux primer
posted on 2015-05-11 21:19:05

Like an earlier post on screen, this is a primer on tmux to get up and running as fast as possible.

tmux 'feels' faster, and has according to rumors, cleaner code, thus crashes not as easily. Also the shortcuts, manpage, everything felt more natural and easier to memorize. As well as ctrl-b being a better shortcuts than screen's ctrl-a which is often needed for jumping to the beginning of the line in bash. And the pane borders are only a pixel wide, which is just great.

In short, on a server, use screen, tmux otherwise. Why? Most likely your peers will know screen already, but do not want to have to do anything with tmux. :)

Further, 'tmux' has sessions containing windows containing panes, whereas 'screen' only has sessions containing panes, as far as I remember.

In the following, every command that does not start with tmux is a hotkey, the former are shell commands. For hotkey commands you have to be within a running tmux session.

global hotkey

# needed for every command you will want to enter inside tmux
CTRL+b

general handling

help

## general help overview, bindings via tmux
?

## bindings via shell
tmux lsk

detach

d

suspend

CTRL-z

show tmux messages

session management

start a named session

tmux new -s <session-name>

kill session

tmux kill-session -t <session-name>

list available sessions

tmux ls

reattach named session

tmux a -t <session-name>

# if only one session is runningï
tmux a

choose session via menu

s

window management

open new window

c

close current window

&

choose window via menu

w

rename current window

,

search for text in all windows

f

moving around windows

# go to previous window
l

# jump to window by id
0, 1, 2, 3, 4, 5, 6, 7, 8, 9

# next/previous window
n / p

choose window via menu

w

pane management

split / open panes

# vertical
%

# horizontal
"

close current pane

x

break current pane out of current window (into new window)

!

moving around panes

just use the arrow keys, the will work, too

# next pane in current window
o

# rotate panes forwards / backwards (so next pane is put where the current was)
CTRL-o / M-o

# show pane id's
q

# jump to pane by number
q <number>

# go to previous pane
;

resizing panes

# by one character
CTRL-<arrow key>

# by five characters
M-<arrow key>

rearranging panes

# swap current with next with pane
}

# swap current with previous with pane
{

scrolling

pgup
pgdn
or use the mousewheel
