Need to quickly generate a QR code from the command line?

Because web services are always better? /s

A simple utility not dependent on internet:

  qrencode -t ansi https://link.com

Or if you like an image:

  qrencode "$something" -o a.png && eog a.png

Copy-paste friendly prompt:

  read a && qrencode -o a.png -- "$a" && eog a.png
