control shell provides commands that continue stopped process groups in either the foreground or back-
ground. The terminal driver also stops a background process group when any member of the background
process group attempts to read from or write to the user’s terminal. This allows the user to finish or
suspend the foreground process group without interruption and continue the stopped background
process group at a more convenient time.
See stty(1), sh(1), and related shell entries for usage and installation details, and the shell entries plus sig-
nal(2) and termio(7) for implementation details.
kernel
The HP-UX operating system. The kernel is the executable code responsible for managing the computer’s
resources, such as allocating memory, creating processes, and scheduling programs for execution. The ker-
nel resides in RAM (random access memory) whenever HP-UX is running.
LANG
An environment variable used to inform a computer process of the user’s requirements for native
language, local customs, and coded character set.
legacy device special file
A special file associated with an I/O device (tape, disk, and so on), locked to a particular physical
hardware path, containing hardware path information such as SCSI bus, target, and LUN in the device
file name and minor number. See intro(7) for more information.
legacy hardware path
A hardware path following the legacy format conventions, that is, a series of bus-nexus addresses separated
by
/ (slash) characters, leading to a host bus adapter (HBA). Beneath the HBA, additional address ele-
ments are separated by . (period) characters. All elements are represented in decimal. See intro(7) for
more information.
library
A file containing a set of subroutines and variables that can be accessed by user programs. Libraries can be
either archives or shared libraries. For example,
/usr/lib/libc.a
and /usr/lib/libc.sl are
libraries containings all functions of Section 2 and all functions of Section 3 that are marked (3C) and (3S)
in the HP-UX Reference. Similarly,
/usr/lib/libm.a
and /usr/lib/libm.sl are libraries con-
taining all functions in Section 3 that are marked (3M) in the HP-UX Reference. See intro(2) and intro(3C).
LIF
See Logical Interchange Format.
line
A sequence of text characters consisting of zero or more nonnewline characters plus a terminating newline
character.
link
Link is a synonym for directory entry. It is an object that associates a file name with any type of file.
The information constituting a link includes the name of the file and where the contents of that file can be
found on a mass storage medium. One physical file can have several links to it. Several directory entries
can associate names with a given file. If the links appear in different directories, the file may or may not
have the same name in each. However, if the links appear in one directory, each link must have a unique
name in that directory. Multiple links to directories are not allowed (except as created by a user with
appropriate privileges). See ln(1), link(2), unlink(2), and symbolic link.
Also, to prepare a program for execution; see linker.
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 exe-
cuted through the program loader, exec(2). The linker is invoked with the ld(1) command. The linker is
often called a link editor.
