Right, calling system() or `` does fork another process along with all the respective overhead. But I'm not sure that your method doesn't do this too. I've never seen that idea before. The way to check is to use perl to do a system call of a program that prints the current process list and then seeing which methods create an extra process to do this. I'd wager that they all do.
