I am but a struggling acolyte, and profess no expertise .... the code below is glommed from a script I currently use (and apparently works) ... hope it helps

my $wget_file = '/path/to/file/that/contains/retrieved/data';
my $wget_url = 'http://www.wherever.com/directory/retriev_file.html';
my $wget_path = '/path/to/wget';
my $output = system("$wget_path -O $wget_file $wget_url");
