Another script originating from a debugging session (like
swaptop) is
zombies, a
convenient way to list all zombie processes and what you need to kill
to get rid of them:
% zombies
xdg-open/2776 zombie child of hotot/29421
firefox-limited/26341 zombie child of firefox/26337
The implementation is simple, but uses the neat trick of tree-sorting the processes to ensure parents processes are seen before their children.
