Convert MD to 2 (Man Page)

The MD file extension stands for "Markdown Documentation", a lightweight markup language used primarily for creating formatted text using a plain-text editor. Originally created by John Gruber in 2004, Markdown aims to be an easy-to-read and easy-to-write syntax for web content creation. Its primary use is in documentation files, readme files, and other technical documents where both simplicity and readability are paramount. The MD extension facilitates smooth conversion into HTML and other formats, making it an essential tool for developers and technical writers.

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.
