In this tutorial we are going to unleash what may be the coolest feature of the command line. It's called I/O redirection. The I/O stands for input/output and with this facility you can redirect the input and output of commands to and from files, as well as connect multiply commands together into powerful command PIPELINES. Precisely in this tutorial I'm going to cover Standard Output and Error, but not Input, because there are many different subjects I need to cover in standard input, and it is much better for understanding if I just split "std output and error" in one, and "standard input" in other video tutorial.
