    You can't catch SIGKILL. It is the nature of this signal that no program can handle it. A program that receives SIGKILL just crashes and that's that.

    SIGTERM can be handled; in fact many programs handle it by cleaning up their resources, closing files and so on, then exiting. You can write a program to handle SIGTERM in whatever way you desire and then test it by sending it a SIGTERM using the kill command.
