Linux File System

The Linux File System adopts a hierarchical tree directory structure. The top layer is "/", and other directories are created below, linux allows manufacturers and individuals to modify the operating system, which may cause directory inconsistency. Therefore, a set of standardized file directory naming and storage standard files are developed. This is: filesystem Hierarchy Standard (FHS). Publishers, including the RedHat manufacturer, must comply with this standard. If you are interested, you can refer to this address for instructions:
