Which command is used to view the manual page of a command in Linux?

The 'man' command (short for manual) is specifically designed and widely used in Unix-like operating systems like Linux to display the reference documentation or 'man pages' for commands, utilities, and functions.

'info' is used to view GNU info documents, which are different from traditional man pages, offering hyperlinked, tree-structured documentation.

'help' is typically a shell built-in command used to get help on shell built-in commands themselves, not external utilities or applications.

'doc' is not a standard Linux command for viewing manual pages; it might be part of other software or a directory name.
