TIL: TMUX pane management

:til: :tmux:

Inside any pane, press <Prefix>! and tmux will create a new window from your pane, removing the original pane.

Now, to move the first window into a pane in the second window, press <Prefix>: to enter Command mode, and type this:

:join-pane -s panes:1


:join-pane -s :1

You can use this technique to move panes around as well. If your first window had two panes, you could specify the source pane like this:

:join-pane -s panes:1.1

The resize-pane command accepts the -Z option for zooming a pane. Best of all, it’s already mapped to <Prefix>z, and pressing it again restores the pane to its original size.
