Convert WRI to 9 (Man Page)

The WRI file extension stands for Microsoft Write Document, a text document format created using Microsoft Write, a basic word processor included in early versions of Windows (Windows 1.0 to Windows NT 3.51). WRI files typically contain styled text and page formatting information, such as formatted letters or resumes. Microsoft discontinued Write with the release of Windows 95, replacing it with Microsoft WordPad, which led to the decline in the use of WRI files. Despite this, several modern word processing programs can still open and convert WRI files to more common formats like DOCX, RTF, and TXT.

The 9 file extension refers to Section 9 of the Unix manual pages, specifically covering Kernel Routines. These manual pages provide detailed information on kernel APIs, internal structures, and other essential aspects of kernel development. Developed by Dennis Ritchie and Ken Thompson at AT&T Bell Laboratories in 1971, Section 9 is crucial for kernel developers but is not universally available due to its specialized nature.
