Help with shellHook trap and nushell

Help

      shellHook = ''
        PS1="\[\e[1;32m\][(${nix_shell_name})\u@\h:\w]\$\[\e[0m\] "
        docker start mariadb-temp >/dev/null 2>&1 || true
        setsid python-service </dev/null >/dev/null 2>&1 & 
        SERVICE_PID=$!
        
        trap '
          docker stop mariadb-temp >/dev/null 2>&1 || true
          kill $SERVICE_PID 2>/dev/null || true  
        ' EXIT INT TERM
      '';

So I have a shellHook which looks like the above, its inteded purpose is to start docker and python-service and then trap and kill them upon shell exit.

The above successfully kills the process upon exit if I use nix develop but does not when I use nix develop -c $env.SHELL (I am using nushell btw)

How can I get it to kill the process on nix develop -c $env.SHELL

I guess I could add

exec nu to the end of my shellHook and just use the command nix develop but that feels a bit ad-hoc as the flake shouldn’t choose the shell.

Thoughts?

Thanks for the help,
Vatsa

Just don’t. Instead start and stop auxiliary services by hand.
