The unix shell was designed to optimize for simple pipes. to make pipe networks you usually have to use named pipes, aka fifos. I once had to use an IBM mainframe shell(cms If I remember correctly) which had pipes however IBM in their infinite wisdom decided to make the pipe network the primary interface, while this made complex pipes a bit less awkward, simple(single output) pipes were wordy compared to the unix equivalent.
