FHS (Filesystem Hierarchy Standard)

The Filesystem Hierarchy Standard (FHS) is a set of guidelines for organizing files and directories in Unix-like operating systems, including Linux. It ensures a consistent structure across different systems, making it easier for users and software developers to find files. For example, system binaries go in `/bin`, user programs in `/usr`, and configuration files in `/etc`. By adhering to FHS, different distributions of Linux can maintain a familiar layout, which enhances usability and simplifies system management. This standard helps both novice and experienced users navigate and interact with the operating system more efficiently.
