How to terminate a window in tmux?

try Prefix + &

if you have

bind q killp

in your .tmux.conf, you can press Prefix + q to kill the window too, only if there is only one panel in that window.

if you have multiple panes and want to kill the whole window at once use killw instead of killp in your config.

the default of Prefix above is Ctrl+b, so to terminate window by default you can use Ctrl+b &

<Prefix> & for killing a window

<Prefix> x for killing a pane

If there is only one pane (i.e. the window is not split into multiple panes, <Prefix> x would kill the window)

As always iterated, <Prefix> is generally CTRL+b. (I think for beginner questions, we can just say CTRL+b all the time, and not talk about prefix at all, but anyway :) )

Generally:

tmux kill-window -t window-number

So for example, if you are in window 1 and you want to kill window 9:

tmux kill-window -t 9
