Chapter 14. Process Management

One of the best parts of being a programmer is launching someone else's code so you don't have to write it yourself. It's time to learn how to manage your children[*] by launching other programs directly from Perl.

[*] Child processes, that is.

Like everything else in Perl, There's More Than One Way To Do It, with lots of overlap, variations, and special features. If you don't like the first way, read on for another page or two for a solution more to your liking.

Perl is very portable. Most of the rest of this book doesn't need many notes saying that it works this way on Unix systems, that way on Windows, and the other way on VMS. But when you're starting other programs on your machine, different programs are available on a Macintosh than you'll likely find on a Cray. The examples in this chapter are primarily Unix-based; if you have a non-Unix system, expect to see some differences.
