Unix Section 6 Manual Page: Games and Screensavers (.6)
The 6 file extension refers to Unix Section 6 Manual Pages, which document games and screensavers in Unix-based systems. These manual pages, accessible via the "man" command, provide instructions and details about various entertainment programs. Originating from the Unix Programmer's Manual developed by Dennis Ritchie and Ken Thompson in 1971, these files offer insights into text-based and graphical games, such as "fortune", "cowsay", and "tetris".
