Useful built-in macOS command-line utilities

There is also pmset which is very useful (since macOS doesn't give a UI counterpart) https://support.apple.com/en-am/guide/mac-help/mchl40376151/...

Oh this is pretty neat, thanks for sharing!

I have this .zshrc function to track the battery and charging, which uses pmset:

    function batt-info() {
        echo
        system_profiler SPPowerDataType | grep Wattage | cut -c 7-
        echo
        pmset -g batt
    }

I've found reliably "turning on" with pmset to be hit or miss. I can't remember the gotcha I ran into if it was that you had to have your laptop lid open or something else...
