Redirect data streams with pipes
Conclusions
Pipes are not just for long command chains; they also serve as very interesting tools for communicating between multiple processes. Because the system treats pipes like normal files, in combination with the ability to redirect channels, pipes offer a very flexible interface on many Unix and Linux systems. The fact that pipes can be addressed identically on all Unix and Linux derivatives is also a big help and keeps the application transparent to the user at all times.
