Perl code to retrieve text from website

Code:
  perl -MLWP::Simple -le '$s=shift;$c=get("http://www.google.com/intl/en/chrome/devices/chromecast/$s/");$c=~/meta content=(.*?)name=\"Remote free\"/msg; print length($1),"\t$1"' ?gclid=CJDg27OdnL0CFcFlOgodFD8A6Q >output.txt

output.txt should be: Chromecast works with devices you already own, including Android tablets and smartphones, iPhones®, iPads®, Chrome for Mac® and Chrome for Windows®. Browse for what to watch, control playback, and adjust volume using your device. You won't have to learn anything new

The script above creates a 1KB file, but it is empty. I have also tried another site with this code with the same result and I do not know why or how to fix it.

Code:
 perl -MLWP::Simple -le '$s=shift;$c=get("http://www.ncbi.nlm.nih.gov/gtr/tests/508680/$s/");$c=~/meta content=(.*?)name=\"Test name\"/msg; print length($1),"\t$1"' #overview

output.txt should be: Whole Exome Sequencing (Exome)


Thanks.
