Logic File System

Welcome to LFS, the filesystem of discriminating hackers.

• 5 Jul 2008: First tutorial draft
• 3 Jul 2008: A fresh new LFS website !!
• 30 Jun 2008: A new version of LFS, LFS 0.5, far less invasive allowing the user to keep his traditionnal files as-is. LFS just acts like an additionnal way to access your files. No need to migrate your data to LFS.
• 1 Sep 2000: Start of my PhD on LFS (yes, 8 years before a real website, I know, I sux)

It's the filesystem you always wanted. It's a Semantic_File_System.

$ ls '/lfs/ext:c|ext:h/date:*--*--2008/.ext/'

$ mplayer  -z '/lfs/ext:mp3/genre:Disco|genre:Electro/year:<70/.ext/'*.mp3

$ firefox 'http://aryx.kicks-ass.org/~pad/lfs_view.query/ext:pdf/.ext/'

Here are additional examples of use of LFS:

• demo-homedir
• demo-gentoo-packages
• demo-ubuntu-packages
• demo-linux-source
• demo-mp3
• demo-mp3-itunes
• demo-pictures
• demo-code
• demo-porn
• demo-gnus-email
• demo-man-pages
• demo-pof-bibtex
• demo-pof-code
• demo-pof-latex
• demo-pof-constitution
• demo-pof-java
