The Catalina update reminder

If you, like me, have no interest in moving to macOS Catalina, you may want to remove the annoying update reminder from the System Preferences icon in the Dock. I’ve seen various suggestions for how to do so. This one works. It’s easy: uncheck three boxes in Software Update and paste three lines of code, one at a time, into the Terminal. Following these steps also removes the update reminder from the Software Update icon in System Preferences.

If you click on Software Update, the reminder will return. That’s how I got the reminder back to get a screenshot for this post. But you can remove the reminder again. And here’s another reminder: Software Update is not the App Store. Update notifications from the App Store are welcome things.
