How do you display the manual page of a command?

To display the manual page of a command in Linux, the correct method is to use the man command followed by the name of the command whose manual you wish to view. The man command stands for "manual" and accesses the built-in documentation for commands, system calls, libraries, and more. When executed, it presents a formatted page that explains the command's usage, options, and related commands, making it an essential tool for both new and experienced users to understand how to use various command-line utilities effectively.

The other options provide different types of help but do not specifically serve the same purpose as the man command. The help command mainly shows built-in shell commands and is not applicable for external commands or utilities. The info command is used for displaying more detailed documentation in a different format, typically covering commands as well, but it does not replace the man command for retrieving standard manual pages. Lastly, the doc command is not a standard command in Linux for displaying manual pages and may not even exist in typical installations, making it unsuitable for this purpose.
