I/O redirection
A mechanism provided by the HP-UX shell for changing the source of data for standard
input and/or the destination of data for standard output and standard error. See sh(1).
ITE See Internal Terminal Emulator.
job control Job control allows users to selectively stop (suspend) execution of processes and continue
(resume) their execution at a later time.
The user employs this facility via the interactive interface jointly supplied by the system
terminal driver and certain shells (see sh(1)). The terminal driver recognizes a user-
defined ‘‘suspend character’’, which causes the current foreground process group to stop
and the user’s job control shell to resume. The job control shell provides commands that
continue stopped process groups in either the foreground or background. The terminal
driver also stops a background process group when any member of the background pro-
cess 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 signal(2) and termio(7) for implementation details.
kernel The HP-UX operating system. The kernel is the executable code responsible for manag-
ing the computer’s resources, such as allocating memory, creating processes, and schedul-
ing programs for execution. The kernel resides in RAM (random access memory) when-
ever 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.
library A file containing a set of subroutines and variables that can be accessed by user pro-
grams. 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 ter-
minating 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 sym-
bolic 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 for-
mat. 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 char-
acter set requirements of a particular geographical area.
