link count
The number of directory entries that refer to a particular file.
linker
A program that combines one or more object programs into one program, searches libraries to resolve
user program references, and builds an executable file in
a.out format. This executable file is ready to
be executed through the program loader, exec(2). The linker is invoked with the ld(1) command. The
linker is often called a link editor.
local customs
The conventions of a geographical area or territory for such things as date, time and currency formats.
localization
The process of adapting existing software to meet the local language, customs, and character set require-
ments of a particular geographical area.
Logical Interchange Format (LIF)
A standard format for mass storage implemented on many Hewlett-Packard computers to aid in media
transportability. See lif(4) for more detail.
login
The process of gaining access to HP-UX. This consists of successful execution of the login sequence
defined by login (1), which varies depending on the system configuration. It requests a login name and
possibly one or more passwords.
login directory
The directory in which you are placed immediately after you log in. This directory is defined for each
user in the file
/etc/passwd. The shell variable HOME is set automatically to your login directory by
login(1) immediately after you log in. See home directory.
LUN
LUN refers to an end device, such as a disk or tape or a piece of logical storage in a disk array (mass
storage term). Also known as a Logical Unit (LU).
LUN hardware path
A virtualized path that can represent multiple paths to a single mass storage device. It starts with a vir-
tual bus-nexus (known as the virtual root node) with an address of 64000. Addressing beneath that
virtual root node consists of a virtual bus address and a virtual LUN identifier, delimited by
/ (slash)
characters. See intro (7) for more information.
lunpath hardware path
A hardware path to a LUN. It is composed of a series of bus-nexus addresses separated by
/ (slash) char-
acters, leading to a host bus adopter (HBA). Beneath the HBA, additional address elements are
represented in hexadecimal. The first elements represent a transport-dependent target address. The
final element is a LUN address, which is the 64-bit representation of the LUN identifier reported by the
target. See intro (7) for more information.
magic number
The first word of an
a.out format or archive file. This word contains the system ID, which states what
machine (hardware) the file will run on, and the file type (executable, sharable executable, archive, etc.).
major number
A number used exclusively to create special files that enable I/O to or from specific devices. This number
indicates which device driver to use for the device. Refer to mknod(2) and the System Administrator
manual supplied with your system for details.
message catalog
Program strings, such as program messages and prompts, are stored in a message catalog correspond-
ing to a particular geographical area. Retrieval of a string from a message catalog is based on the value
of the user’s
LANG environment variable (see LANG).
