You need the LWP module installed, and also the tools that LWP offers to install. The GET programm is not much more than the following Perl oneliner:

# for Windows
perl -MLWP::Simple -e "getprint 'http://www.example.com/'"

# for Unix
perl -MLWP::Simple -e 'getprint q(http://www.example.com/)'

You can also directly store the result in a file using the mirror command of LWP::Simple:

perl -MLWP::Simple -e 'mirror q(http://www.example.com),"example-store
+d-page.html"'

Looking back at your previous posts, please think about how you can make your node titles a bit more descriptive. For example, for this node, a title like How to save the result of a http request in a file might have been more descriptive.

perl -MHTTP::Daemon -MHTTP::Response -MLWP::Simple -e ' ;    # The  
$d = new HTTP::Daemon and fork and getprint $d->url and exit;#spider
($c = $d->accept())->get_request(); $c->send_response( new   #in the
HTTP::Response(200,$_,$_,qq(Just another Perl hacker\n))); ' #  web
