A well behaved app should catch SIGTERM and do proper cleanup before shutdown so that when a user does kill <pid_of_app> it shuts down cleanly. kill -9 <pid_of_app> shouldn't normally be needed - it is for emergency termination of the app, which is why you can't catch it. -- Jesper Juhl <jesper.juhl@gmail.com> Don't top-post http://www.catb.org/~esr/jargon/html/T/top-post.html Plain text mails only, please http://www.expita.com/nomime.html - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
