Lesson 12: Connecting Commands with Pipes

Here's where the terminal's magic happens. The `|` (pipe) sign takes the output of one command and feeds it straight into the next. That's how you connect small tools into one big solution.

Pipe (|): A sign that passes one command's output as input to the next
Standard output: The text a command prints, which can be passed onward
wc -l: A command that counts lines in the text it receives
