Last I checked a keyboard only enters what I type

I’ve had (broken) keyboard “hallucinate” extra keystrokes before, because of stuck keys. Or ignore keypresses. But yeah, that means the keyboard is broken.

TIL about systemd-analyze security. Thanks!

I had a similar construct in my bashrc and forgot the quotes. It didn’t throw an error but also didn’t work. Took quite a while to find the issue. So personally, I would recommend trying to quote correctly whenever possible.
