[ILUG-BOM] [OT] Pipes & redirection doubt

Dear friends,

While going thru' the chapter of Pipes & Redirection from the *The Unix Programming Environment* (the famous yellow book by Kerninghan, et al) I read that when we use redirection, the system uses some temporary files to accomplish the task. Whereas by using pipes, the overhead of temp. files can be avoided.

Can someone throw some more light on it? Like, why shud there be requirement of temporary files, where are those temp. file stored?

I tried to find some more details on it in the docs as well as on the net, but the search wasn't very much fruitful.

Thanks in advance.

Warm Regards, $ sonpal -kj
