Save it into another file

qrrs --read --terminal /tmp/qr.png /tmp/qr1.png

Almost the same result will be without terminal flag, but now instead of QrCode printed in terminal we will see text from it.

qrrs --read /tmp/qr.png /tmp/qr1.png

Create code using pipeline

Use "-" to signalize passing data via stdin.

$ echo "something" | qrrs - /tmp/something.png
$ qrrs -r /tmp/something.png
something

Invert colors

Create code specifying it's margin
