Is there a way to implement something like screen's zombies in tmux?

[Morgan, Iain (ARC-TNC)[InuTeq, LLC]]

Hi,

Currently, I use a hook to call "confirm respawn-pane" when the command in the pane has terminated. That works fine in cases where I want to respawn the pane, but I'd like tmux to kill the pane if I do not select to respawn it.

Essentially, if I enter "y" at the confirmation prompt, I want to respawn the pane, but I want the pane to be killed if I enter 'n." Is there a way to do this in version 2.7 or 3.2a?

Thanks,

Instead of using confirm use a custom prompt. This works for master, I can't tell you about 3.2, you may have to adapt it:

set -g remain-on-exit on
set-hook -g pane-died {
    command-prompt -1p 'Respawn pane #{pane_id}?' "if -F '#{m/r:[Yy],%1}' 'respawnp' 'killp'"
}

Thanks for putting me on the right track. With some slight adjustment, I managed to get this to work for both 3.2a and 2.7.

set -g remain-on-exit on
set-hook -g pane-died "command-prompt -1p 'Respawn pane? (y/n)' \
\"if -F '#{m:[Yy],%1}' respawn-pane kill-pane\""
