Handle SIGQUIT

[jasontwong]

For some reason the process doesn't quit with Ctrl + \ but does with Ctrl + c.

SIGQUIT is the dump core signal. The terminal sends it to the foreground process when the user presses ctrl-\. The default behavior is to terminate the process and dump core, but it can be caught or ignored. The intention is to provide a mechanism for the user to abort the process.

@kenwheeler For some reason the following piece of code isn't being recognised by Node. Also, listening for the 'C-' event doesn't work since the backslash will need to be escaped (and isn't recognised as a valid key combination anymore).

process.on("SIGQUIT", function () {
  process.exit(0);
});

Other terminal apps, like Node itself, don't quit with Ctrl + \ either. Is this still a valid way to quit processes?

express and webpack --watch work with Ctrl + \. So does irb, yes, grep, etc. But you are correct that the node REPL does not support it. Maybe it should be handled upstream on node?
