Filesystem Hierarchy Standard (
FHS) defines a common
arrangement of the many
files and
directories in
Unix-like systems (the filesystem hierarchy) that many different
developers and
groups 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.
