Using system creates another process, exec is more appropriate here.

If you are running on Windows you should be aware that fork creates a new thread, not a new process (fork is UNIX architecture). Also (on Windows) to run a script you should prefix the script name with 'perl', since file extension association is done at application, not OS, level. See also Win32::Process and Win32::FetchCommand.
