sudo apt install tmux
tmux kill-server
tmux kill-window -t <windowname>

Press your tmux prefix key (default is Ctrl+B) followed by : to open the command prompt, then type kill-window and press Enter. Alternatively, you can use Ctrl+B & to kill the current window and confirm with y to really kill the window including all panes within it.

Save tmux sessions to persist restart #
To save tmux sessions to persist a restart, you can use the tmux-resurrect plugin. This plugin saves all the details from your tmux environment so it can be completely restored after a system restart. To install tmux-resurrect, add the following line to your .tmux.conf file:
set -g @plugin 'tmux-plugins/tmux-resurrect'
After adding this line, press prefix + I within a tmux session to fetch and install the plugin. To save your tmux environment, press prefix + Ctrl-s. To restore the saved environment, you can use prefix + Ctrl-r.
For automatic saving and restoring of the tmux environment, you can also use the tmux-continuum plugin. This plugin saves the tmux environment every 15 minutes and can be installed similarly to tmux-resurrect.
To ensure vim sessions are restored, install Tim Pope’s vim-obsession plugin.

resize pane #
In order to resize tmux panes, you first hit your tmux prefix (ctrl + b is the default one. Mine is ctrl + a.), and then the colon key :. This brings up a tmux command mode prompt at the bottom of your screen.
:resize-pane -L 20 # Resizes the current pane Left by 20 cells
:resize-pane -R 20 # Resizes the current pane Right by 20 cells
:resize-pane -D 20 # Resizes the current pane Down by 20 cells
:resize-pane -U 20 # Resizes the current pane Upward by 20 cells

start new:

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 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:

⍽ 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 -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.
