# python2-qr(1)

script to create QR codes at the command line

## NAME

qr - script to create QR codes at the command line

## SYNOPSIS

qr \[--help\] \[--factory=FACTORY\] \[--optimize=OPTIMIZE\] \[--error-correction=LEVEL\] \[data\]

## DESCRIPTION

This script uses the python qrcode module. It can take data from stdin or from the commandline and generate a QR code. Normally it will output the QR code as ascii art to the terminal. If the output is piped to a file, it will output the image (default type of PNG).

## OPTIONS

- **-h, --help**

  Show a help message.

- **--factory=FACTORY**

  Full python path to the image factory class to create the image with. You can use the following shortcuts to the built-in image factory classes: pil (default), pymaging, svg, svg-fragment, svg-path.

- **--optimize=OPTIMIZE**

  Optimize the data by looking for chunks of at least this many characters that could use a more efficient encoding method. Use 0 to turn off chunk optimization.

- **--error-correction=LEVEL**

  The error correction level to use. Choices are L (7%), M (15%, default), Q (25%), and H (30%).

 **data**

The data from which the QR code will be generated.
