Glossary
absolute path name The name of a file
which lists all the directories leading to
it, starting with root ("/") and ending
with the file base name itself. If the path
name indicates a directory, leave the
trailing slash. For example, /users/jth/.
See Using HP-UX for more information
on path names and directory structures in
HP-UX.
access permissions File name charac-
teristics (including read, write, and exe-
cute) which determine whether a process
can perform a requested operation on the
file (such as opening a file for writing).
Access permissions can be changed by a
chmod(1) command.
alternate boot path The address at
which the firmware searches for a boot
device, if it has not found the device
specified by the primary boot path.
application A program used to perform
a particular task, usually interactively,
such as computer-aided design, text edit-
ing, or accounting.
argument The part of a command line
which identifies what (file, directory,
etc.) is to be acted upon.
ASIC Application Specific Integrated
Circuit.
backup A copy of all or part of the file
system.

boot device A device such as a disk
drive, DDS tape drive, or network device
that contains the appropriate program for
booting the operating system.
boot ROM A EEPROM memory
which is incorporated into a system for
the purpose starting the operating sys-
tem, testing the terminal, and producing
a standard display. Thought loosely re-
ferred to as ROM, it includes a writable
function to allow reconfiguration of path
and boot-configuration information.
Bourne Shell A command interpreter,
invoked as /bin/sh. The Bourne Shell is
the default shell in HP-UX.
bus address A number which makes
up part of the address HP-UX uses to lo-
cate a particular device. The bus address
is determined by a switch setting on a pe-
ripheral device which allows the com-
puter to distinguish between two devices
connected to the same interface.
button A graphic element in a display
that functionally represents an actual
push button. It is usually accessible by
mouse pointer and is used to start an ac-
tion.
CD-ROM Compact Disc Read-Only
Memory.
CD ROM file system A read-only
memory file system on compact disk.
Typically, you can read data from a CD
ROM file system, but you cannot write
to one.

ganization, control, or representation of
text. Characters include graphic charac-
ters and control characters.
