Filesystem Hierarchy Standard
) defines a common arrangement
of the many files
-like systems (the filesystem hierarchy) that many different developers
have agreed to use. See http://www.pathname.com/fhs/ for more details
The FHS specification is used by the implementors of Linux distributions and other Unix-like operating systems, application developers, and open-source writers. In addition, many system administrators and users have found it to be a useful resource.
FHS or its predecessor, FSSTND, is currently implemented by most major Linux distributions, including Debian, Red Hat, Caldera, SuSE, and more.
