in thread Closing a system process after file creation (was: One for the Wisest Monks)

system "touch $num.bat";

But that unnecessarily starts a separate process, and is subject to security issues regarding the contents of $num.

Much safer and faster: 

open DUMMY, ">>$num.bat";
close DUMMY;

    doesn't suffer from security issues regarding the content of $num. As for "much faster", I'm not quite convinced. You're doing disk I/O here, and that's likely to be the bottleneck anyway.
