This page is the home of the Filesystem Hierarchy Standard (FHS). The current version is 2.3. It was announced on January 29, 2004.
The filesystem standard has been designed to be used by Unix distribution developers, package developers, and system implementors. However, it is primarily intended to be a reference and is not a tutorial on how to manage a Unix filesystem or directory hierarchy.
FHS Documents, Resources, and Links
The official home for the FHS specification at the Linux Foundation is at our Reference Specifications site.
The mailing list is available to discuss interpretations of the FHS document and of possible future changes and additions.
Development on the FHS is managed in the Bazaar version control system. Interested developers can browse the source code for the specification here, or check out their own copy from http://bzr.linuxfoundation.org/lsb/devel/fhs-spec.
All proposals should be submitted as bugs on bugs.linux-foundation.org using the "FHS" component). Please include a unified patch or Bazaar bundled revision to the XML source, either the last released version or the current in-progress version, when proposing a change in the bug tracker (create the attachment after you've opened the bug; please do not cut-and-paste patches into comments).
