I think you may be a little confused.

$ARGV[0]=$d;
[download]

This overwrites the first command line argument with the value of $d - which is undefined.

shift=$d;

This doesn't even compile.

I was a lot confused

#!/usr/local/bin/perl -w
use strict;

my $d;
$d = shift; #this wiill work
print "$d\n"; #will print argument

OR


#!/usr/local/bin/perl -w
use strict;

die "argument required\n" unless defined $ARGV[0]; # will stop the scr
+ipt if there is no argument
print "This is what I ment $ARGV[0]\n";

I screwed that one up good. This is better and tested
