Lived in California (SoCal and Bay Area) my entire 42 years.

No, we don’t.

There was a short, planned outage in my neighborhood (San Diego suburbs) last summer - we got a few days notice (can’t recall if it was a letter or an email). Didn’t have one the summer before that. I don’t recall any power outages when I lived in the Bay Area.

I’m addition to tldr which someone else suggested, there’s also the cheat command. It’s pretty easy to add to it’s cheat sheets, if you have custom commands, or want to keep a specific example. I’ve never kept a physical cheat sheet… They’re just too inconvenient and my fingers are probably already at the keyboard.
