Man pages

Man pages, short for "manual pages," are built-in reference guides on Unix and Linux systems that provide detailed information about commands, programs, and functions. They help users understand how to use various tools effectively by offering descriptions, options, and examples. Accessible via the `man` command followed by the name of the command or program, man pages serve as comprehensive, searchable documentation that assists users in troubleshooting and learning about system features without needing internet access or external resources.
