Convert 2 (Man Page) to MKDN

A 2 file extension refers to a Unix manual page (man page) that documents a specific system call. These files are part of the Section 2 of the Unix manual, which is dedicated to system calls. Each 2 file is named after the system call it describes, such as "link.2" for the "link" system call. These files are intended to be viewed using the "man" utility in Unix-based systems. Historically, they have been a fundamental part of Unix documentation, providing detailed information on how to use system calls, their return values, possible errors, and related manual pages.

An MKDN (Markdown Documentation) file extension is utilized primarily for creating structured text documents using Markdown language, which is a lightweight markup language. This language simplifies the process of formatting text, converting it into HTML, and enhancing readability with plain text formatting syntaxes. MKDN files are highly favored for documentation in software development, due to their ability to seamlessly integrate with various tools and platforms, providing an efficient way to maintain and share documentation.
