Sorry for opening an old thread but I arrived to this one as one of my requirements is to also pass arguments to the command as $0 and $1. Can you please suggest how to append this code that it also works with arguments ? 
          echo "$var1 and $var2 can be read here";
          open my $fh, "|-", "sudo su - APP" or die "can't run sudo: $
+?";
          print $fh <<'          _EOF_';
          ls
          echo "$var1 and $var2 can't be found here ? :( "
          _EOF_
          close $fh;
