Can mix tasks be gracefully shutdown?

Is there any way to handle task termination gracefully?

When i do ctrl-c no form for shutdown hook is called in the task. I have yet to see an example or google search hit for something that shows how this can be solved.

Is it a futile project and a dead end? Will mix tasks always be hard killed with no way to gracefully shutdown?

Btw. It is solved. By not using System.cmd and instead running tasks via Mix.Task.run. When i ran the task via System.cmd the spawned task outlived the task it was spawned from.

I started using Ctrl + \ a while back and I think it is more graceful than Ctrl + c.

Well, Ctrl-C sends a SIGINT signal to the process. You should be able to do what you want using the signal handling capabilities of the kernel, more specifically erl_signal_server.
