Need an expert to clarify hexadecimal and octal notation? This month in Unix 101, Mo Budlong continues his three-part series on Unix security with a closer look at file attribute bits and modes. While everyone knows that computers are binary, not many people understand the numbering systems that represent the binary numbers stored in computers, or the notational conventions used for displaying this information.

    This may be a teensy bit painful, but I need to cover it to further explain setting file modes. If you understand binary numbering, feel free to skip ahead.
