title: kill -INT vs kill -TERM
body: <p>What's the difference between the <code>SIGINT</code> signal and the <code>SIGTERM</code> signal? I know that <code>SIGINT</code> is equivalent to pressing <kbd>ctrl</kbd>+<kbd>c</kbd> on the keyboard, but what is <code>SIGTERM</code> for? If I wanted to stop some background process gracefully, which of these should I use?</p>
