Instalar Tmux

Terminal:

sudo apt-get install tmux

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

$  tmux attach -t 0  #if session number is 0

$  tmux attach -d   #recover better

$  tmux detach -a  #restore size windows client
$  name session

tmux                           # new tmux session
tmux new -s mySession          # new session with a name
tmux ls                        # list sessions
tmux a                         # attach to session
tmux a -t mySession            # attach to a named session 
tmux kill-session -t mySession # kill session
Ctrl-a d                       # dettach from a session

Ctrl-a s                       # list session and select with enter

Ctrl-a N                       # new session

Windows (tabs)

Ctrl-a c  # new window
Ctrl-a w  # list windows
Ctrl-a h  # move to previously selected window
Ctrl-a l  # move to the next window
Ctrl-a p  # move to the previous window
Ctrl-a f  # find window
Ctrl-a ,  # name window
Ctrl-a &  # kill window

Panes (splits)

Ctrl-a %       # vertical split
Ctrl-a "       # horizontal split
Ctrl-a o       # swap panes
Ctrl-a q       # show pane numbers
Ctrl-a ←/→/↑/↓ # move focus to left/right/upper/lower pane
Ctrl-a x       # kill pane
Ctrl-a +       # break pane into window (e.g. to select text by mouse to copy)
Ctrl-a -       # restore pane from window
Ctrl-a ⍽       # toggle between layouts
Ctrl-a q       # Show pane numbers
Ctrl-a {       # Move the current pane left
Ctrl-a }       # Move the current pane right
Ctrl-a z       # toggle pane zoom
Ctrl-a !       # close other panes except the current one

<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)

search:

`Ctrlb[`

`/`

`Enter`

Copy mode:
Ctrl-a [ # enter copy mode (then use emacs select/yank keys) or scroll mode
# press CTRL-SPACE or CTRL-@ to start selecting text
# move cursor to end of desired text
# press ALT-w to copy selected text
Ctrl-a ] # paste copied text

copy:

Ctrlb[
Space
Enter

paste:

Ctrlb]

restart pane or tab

So <prefix>+: and then enter respawn-pane -k and press Enter

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.
