Displaying Wi-Fi configuration

¹At the start of the month, I was away at the final EU EDGELESS project plenary meeting. As this was hosted by an industrial partner rather than a University eduroam was of no use to me—I had to use the local guest Wi-Fi.

This was fine in fact—but I was pleasantly surprised to encounter a rather neat Linux networking CLI tool feature I’d not come across before.

I needed to share details with a colleague who arrived after the meeting started. Turns out that, rather than having to copy them in by hand, all I needed to do was run nmcli with appropriate options to get the SSID and password on stdout plus a handy QR code also on stdout for my colleague to point their camera-ful devices at.

Neat.
