Then downloads all the files that are linked from each of the listed Web pages. Note that the location of the download folder is hard-coded to `c:/windows/desktop/grabit/` so you may want to change that before trying. This script is also [available on Github](http://github.com/textarcana/scrapers/blob/643e6e7cb349fa94cbc3fc88e1d55c7b6a262d11/grabit.pl) ## Wait! Do you know about WGet and Curl? This script is legacy. People seem to like it (hey, I still use it) but today I would probably not write my own tool to download multiple files off remote sites. Instead I would likely just use a command-line Web browser like [WGet](http://lifehacker.com/software/top/geek-to-live--mastering-wget-161202.php 'Gina Trapani of Lifehacker, on the way of the WGet ninja') or Curl. [LWP-Request would also do the trick](http://snipplr.com/view/4063/download-linked-jpegs-from-a-web-page-on-the-command-line/) ## do not comment your code like this! For a great explanation of the rather baroque commenting style I was using circa 2001, see [Steve Yegge's excellent article on code style: *Portait of a n00b.*](http://steve-yegge.blogspot.com/2008/02/portrait-of-n00b.html) Of course, when I sit down to write a Perl script today, I [use POD](http://snipplr.com/view/18611/perl-pod-embedded-documentation-example/) to format and publish my comments.

This code toggles between the two states in the simplest possible fashion.
