system is a good solution if the program should be blocking, you have no need to interact with STDIN/STDOUT/STDERR, and you don't need to worry about a timeout. Be aware that any STDOUT or STDERR the program generates will just get tacked onto your perl IO channels.

I'd recommend using a list-based call to avoid escaping complications (e.g. system($executable, @args);) but again, that's generic advice.
