in thread read file from ARGV

Hi nithins,
I think it would be a good practice to check the return of open function and to also close an opened filehandles like

open my $fh,'<',$ARGV[0] or die "can't open file: $!"; ... close $fh or die "can't close file: $!";
Except one is doinguse autodie qw(open close);

If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.
