Filesystem Hierarchy Standard (FHS)

The Filesystem Hierarchy Standard (FHS) is a set of guidelines for organizing files and directories in Unix-like operating systems, such as Linux. It ensures a consistent structure, making it easier for users and software to navigate. For example, it defines where system binaries, user files, and configuration files should be located, such as `/bin` for essential programs and `/etc` for configuration settings. By following FHS, developers can create applications that work seamlessly across different systems, enhancing usability and management of the operating system.
