The purpose of command lines is to let you type instructions directly into the computer so it can do exactly what you tell it to do. Instead of clicking around with a mouse, you type commands, and the computer responds right away. Command lines are helpful for managing files, fixing problems, and running programs quickly.

Some common commands you can use are:
• cd – moves you into a different folder.
• dir (or ls on Mac) – shows everything inside a folder.
• mkdir – creates a new folder.
• copy – copies a file from one place to another.
• del or rm – deletes a file.

These commands make it easier to control the computer and get tasks done faster.
