FHS version 2.3

FHS (Filesystem Hierarchy Standard) version 2.3 defines how files and directories should be organized on Linux and UNIX-like systems. It ensures consistency across distributions, making software installation and system management easier. The standard specifies where system files, user data, temporary files, and applications should reside, promoting a structured, logical layout. This consistency helps developers, administrators, and users navigate and maintain systems efficiently, facilitating interoperability and troubleshooting while maintaining a clear, predictable arrangement of files essential for system stability and security.
