What command is used to display manual pages?

The command that is used to display manual pages is "man." This command provides access to the manual (or "man") pages of various commands and programs available on the system. Each entry typically includes a description of the command, its syntax, available options, and usage examples.

The "man" command is particularly useful for users who want to learn about different commands and how to effectively use them, as it serves as a comprehensive reference guide within the terminal environment.

The other options have their specific functions but relate differently to documentation. "help" typically provides help information for shell built-ins, "info" is used for GNU program documentation which can provide a more detailed description than man pages, and "doc" is not a standard command for accessing documentation in Linux.
