@mala good tip, but:
$ npm install -g qrcode-terminal
oh my god, why -g ?
@mala I started to get excited. I could use pbpaste on the mac for this. Then I realised this is no CLI tool. Because (a) all of nodejs and npm just to have a quick QR code utility? and (b) no one is typing Q-R-C-O-D-E-[HYPH]-T-E-R-M-I-N-A-L in their CLI. Tools that real CLI users use look like 'jq'.
Still, this is brilliant. So I need to find an easier way to get this capability. For now it's still faster to open a window to qrstuff.com (literally less to type!)
