Convert 8 (Man Page) to 9 (Man Page)

The 8 file extension refers to Unix Section 8 Manual Pages, which document system administration commands, daemons, and hardware-related commands. These files are part of the Unix operating system's manual pages and are intended to be viewed using the "man" utility. Each 8 file is named after the command it describes, such as "shutdown.8" for the shutdown command. Historically, Unix manual pages have been a fundamental part of Unix documentation since the early 1970s, providing essential information for system administrators and users.

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.
