Why the Command Line Matters

This lesson explains why the command line still matters in everyday work, even if you already use a graphical interface. You will see how the terminal helps you move faster, repeat tasks reliably, and work across many systems with the same basic skills.

We will focus on the big picture: what the command line is, where it fits in modern workflows, and why it is worth learning before jumping into specific commands. Later lessons will cover navigation, file management, and hands-on terminal practice.
