The signals EXIT HUP INT TERM cover everything I've run into (I'm actually using EXIT SIGHUP SIGINT SIGTERM but presumably it's equivalent).

In basic terms for my purposes these respectively account for a clean exit, the terminal emulator being closed, ctrl-c, the kill command (edit: the default SIGTERM kill -15, not the SIGKILL kill -9)

What's the signal for SIGKILL?

SIGKILL can't be handled. It's the signal you send when you don't want to give the process a chance to handle it.

That's the difference between kill -15 (SIGTERM) and kill -9 (SIGKILL), where SIGTERM shuts down a process gracefully.
