Exercise 1 - Use Streams, Pipes, and Redirects

The Linux shells use pipes (|) as an operator between two commands, where the output of one command is the input of the second command. Redirects are meant to direct the output to a specific file or take the input from a specific file. In this exercise, you will understand how use streams, pipes, and redirects.
