Linux Filesystem Hierarchy

environment variable
A variable that is available to any program that is started by the shell.
ESD
Enlightened Sound Daemon. This program is designed to mix together several digitized audio streams
for playback by a single device.
filesystem
The methods and data structures that an operating system uses to keep track of files on a disk or
partition; the way the files are organized on the disk. Also used to describe a partition or disk that is
used to store the files or the type of the filesystem.
FSSTND
Often the group, which creates the Linux File System Structure document, or the document itself, is
referred to as the 'FSSTND'. This is short for "file system standard". This document has helped to
standardize the layout of file systems on Linux systems everywhere. Since the original release of the
standard, most distributors have adopted it in whole or in part, much to the benefit of all Linux users.
It is now often refered to as the FHS (Filesystem Hierarchy Standard) document though since its
incorporation into the LSB (Linux Standards Base) Project.
GUI
Graphical User Interface. The use of pictures rather than just words to represent the input and output
of a program. A program with a GUI runs under some windowing system (e.g. The X Window
System, Microsoft Windows, Acorn RISC OS, NEXTSTEP). The program displays certain icons,
buttons, dialogue boxes etc. in its windows on the screen and the user controls it mainly by moving a
pointer on the screen (typically controlled by a mouse) and selecting certain objects by pressing
buttons on the mouse while the pointer is pointing at them. Though Apple Computer would like to
claim they invented the GUI with their Macintosh operating system, the concept originated in the
early 1970s at Xerox's PARC laboratory.
