( spawn The spawn process creates non-Postfix processes on request. It listens on a TCP port, Unix domain socket, or FIFO connected to the standard input, output, and error streams. )
I would recommend reading "The UNIX Programming Environment" by Brian W. Kernighan and Robert Pike (Prentice Hall India) to get an understanding of things *NIXish. It is thin yellow paperback which *really* packs a solid punch.
I would advise you to seriously read all available documentation; both online and offline. Wikipedia is a great place to start. You have to realise that to understand things takes patience and efforts.
Hope it helps,
