Create QR codes from a URL.

qrurl() { curl -sS "http://chart.apis.google.com/chart?chs=200x200&cht=qr&chld=H|0&chl=$1" -o - | display -filter point -resize 600x600 png:-; }
like 7300, but doesn't clutter your working directory with old qr.*.png files. This will get the QR barcode, and send it right into ImageMagick's 'display' tool. Usage is the same as 7300; just call this function followed by the URL: qrurl http://xkcd.com

  • QR codes are those funny square 2d bar codes that everyone seems to be pointing their smart phones at. Try the following... qrurl http://xkcd.com Then open qr.*.png in your favorite image viewer. Point your the bar code reader on your smart phone at the code, and you'll shortly be reading xkcd on your phone. URLs are not the only thing that can be encoded by QR codes... short texts (to around 2K) can be encoded this way, although this function doesn't do any URL encoding, so unless you want to do that by hand it won't be useful for that.
