Introduction
The Command Line Interface (CLI) provides three types of input/output (I/O) flow.
- stdin = "Standard In;" input passed to a command
- stdout = "Standard Out;" output from a command
- stderr = "Standard Error;" error output from a command
This means that there are two types of output from any command stdout and stderr. It also means that you can separate them.
