1.	What is plumbing/piping in Linux or Unix?
Answer» Plumbing/ Piping refers to the technique of USING one program's output as an input to another. For instance, Instead of DELIVERING a folder or drive listing to the main screen, it can be piped and delivered to a file, or sent to the printer to print a hard copy. A pipe is a type of redirection (the transfer of standard output to another location) USED in Linux and other Unix-like OPERATING systems to transport the output of one command/program/process to another for additional processing. The Unix/Linux systems allow a command's stdout to be CONNECTED to another command's stdin. The pipe character ‘\|' can be used to do this.
