This mini-entry is a supplemental article for first time Raspberry Pi owners using Windows PCs who are reading my MAME Arcade Game Fun With A Raspberry Pi article. This article not intended to be read stand-alone.

Using the Linux terminal (command line) I am going to explain in thorough detail the mysteries that are the Linux system file permissions for the uninitiated.
