FYI, terminology-wise, what you're talking about is often called a "co-process". A great tool for working with co-processes is IPC::Run. It can work in a "wait for the other process to finish" mode (just run the command), or in a mode that allows you to start up a co-process, and pump it along in the controller process.

Oh, another tool for co-processes is Expect.
