I’ll introduce the qrencode
command for generating QR codes.
While there are several web services that can create QR codes for free, I had some resistance to entering various information on such sites.
So I decided to set up an environment where I could generate QR codes from the CLI to create QR codes safely.
yum install -y qrencode
brew install qrencode
? qrencode — Homebrew Formulae
apt install -y qrencode
qrencode -t ansi "https://example.com/"
qrencode -o qrcode.png "https://example.com/"
qrencode -r input.txt -o qrcode.png
That’s all from the Gemba, where I want to safely generate QR codes with the qrencode
command.
