Which command shows a manual page for a command?

• A. man
• B. info
• C. which
• D. locate

Answer: (A)

Reading command references is done with manual pages, and the command to view them is man. Using it is straightforward: type man followed by the command you want, for example man ls, and you’ll see a structured page that typically includes the name, synopsis, description, options, and examples. This is the standard place to learn how a command works, what its options do, and any caveats. You can also specify a section number if needed, like man 1 ls, to target a specific topic area.

If you’re looking for documentation in a different format, you might encounter info pages, which are a separate documentation system. The other options perform different tasks: one shows where a command is located on the system, and the other searches for files by name rather than displaying their documentation.
