    inside single quotes the $ is just more text, not the start of a variable name

    Try 

    my $req = HTTP::Request->new(GET => "https://www.google.com/?name=$nam
+e");

    or 
    my $req = HTTP::Request->new(GET => 'https://www.google.com/?name='.$n
+ame);

      i tried it bt failed. lets say if the link is like this

      $fname = "john";
$lname = "doe";
$ctry = "canada";
my $req = HTTP::Request->new(GET => 'https://www.google.com/?firstname
+=$fname&lastname=$lname&country=$ctry')

      [download]

      but works with no $ string

      my $req = HTTP::Request->new(GET => 'https://www.google.com/?firstname=john&lastname=deo&country=canada')

        Try splitting up your problem in two parts:

        $fname = "john";
$lname = "doe";
$ctry = "canada";
my $url = 'https://www.google.com/?firstname=$fname&lastname=$lname&co
+untry=$ctry';
print "Requesting ", $url, "\n";
my $req = HTTP::Request->new(GET => $url);

        Also, you might want to learn about single and double quotes and how they differ in behaviour: 

        my $single_quoted = 'https://www.google.com/?firstname=$fname&lastname
+=$lname&country=$ctry';
my $double_quoted = "https://www.google.com/?firstname=$fname&lastname
+=$lname&country=$ctry";

print 'Single quotes:', $single_quoted, "\n";
print "Double quotes:", $double_quoted, "\n";

        It fails because you are still using single quotes.

    If $name is just a simple string like you showed, with no special characters, then huck has given you the answer in regards to interpolation in '$name' vs. "$name".

    However, if you've got any special characters in that string, they need to be escaped properly. Here's one way with URI:

    use URI;
my $name = 'xyz&foo=bar';
my $uri = URI->new('https://www.google.com/');
$uri->query_form(
    name => $name,
    foo  => 'quz',
);
print "$uri\n";

__END__

https://www.google.com/?name=xyz%26foo%3Dbar&foo=quz
