Man Pages
Man Pages (short for manual pages) are a built-in documentation system for Unix-like operating systems, such as Linux and macOS, that provide detailed information about commands, system calls, library functions, and file formats. They are accessed via the 'man' command in the terminal and are organized into numbered sections for easy reference. This tool serves as a primary source of official and comprehensive documentation for developers and system administrators working in command-line environments.
Developers should learn to use Man Pages when working on Unix-based systems to quickly access accurate and detailed documentation without leaving the terminal, which is essential for debugging, learning new commands, or understanding system APIs. It is particularly useful for tasks like scripting, system administration, and low-level programming, as it provides instant access to syntax, options, and examples for tools and functions.
