    I think you may be a little confused.

    $ARGV[0]=$d;

    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
