Which command displays the contents of a file?

Which command displays the contents of a file?

• A. Touch
• B. Cat
• C. Whoami
• D. VLAN

Answer: (B)

Displaying the contents of a file is accomplished by a command that reads the file and prints its text to the screen. That command is cat. It outputs exactly what’s inside the file, and it can show multiple files in sequence by listing their names. You can also pipe its output into other tools or redirect it to another file for further processing. The other options serve different purposes: touch creates or updates a file’s timestamp without showing its contents; whoami displays the current user; VLAN refers to a network configuration concept rather than a file-viewing command.
