NAME

Introduction - an introduction to the HP-UX operating system and the HP-UX Reference

INTRODUCTION

HP-UX is the Hewlett-Packard Company's implementation of an operating system that is compatible with various industry standards. It is based on the UNIX® System V Release 4 operating system and includes important features from the Fourth Berkeley Software Distribution.

Improvements include enhanced capabilities and other features, developed by HP to make HP-UX a very powerful, useful, and reliable operating system, capable of supporting a wide range of applications ranging from simple text processing to sophisticated engineering graphics and design. It can readily be used to control instruments and other peripheral devices. Real-time capabilities further expand the ¯exibility of HP- UX as a powerful tool for solving tough problems in design, manufacturing, business, and other areas where responsiveness and performance are important.

Extensive international language support enables HP-UX to interact with users in any of dozens of human languages. HP-UX interfaces easily with local area networks and resource-sharing facilities. By using industry-standard protocols, HP-UX provides ¯exible interaction with other computers and operating sys- tems. Optional software products extend HP-UX capabilities into a broad range of specialized needs.

The HP-UX Reference is not a learning tool for beginners. It is primarily a reference tool that is most useful for experienced users of UNIX or UNIX-like systems. If you are not already familiar with UNIX or HP- UX, refer to the series of Beginner's Guides, tutorial manuals, and other learning documents supplied with your system or available separately. System implementation and maintenance details are explained in the Managing Systems and Workgroups manual.

MANPAGE ORGANIZATION

The contents of the HP-UX Reference and its on-line counterpart are a number of independent entries called manpages. These are also called manual entries or reference pages.

For convenient reference, the manpages are divided into eight specialized sections. The printed manual also has a table of contents for each volume and a composite index.

Each manpage consists of one or more printed pages, with the manpage name and section number printed in the upper corners. Manpages are arranged alphabetically within each section of the reference, except for the intro page at the beginning of each section. Manpages are referred to by name and section number, in the form pagename(section).

The manpages are available on-line through the man command if the manpages are present on the system. Refer to the man(1) manpage in Section 1 for more information.

Each page in the printed manual has two page numbers, printed at the bottom of the page. The center page number starts over with page 1 at the beginning of each new manpage; it is placed between two dashes in normal typeface. The number printed at the outside corner on each page sequences the printed pages within a section. Users usually locate manpages by the alphabetic headings at the top of the page as when reading a dictionary.

Some manpages describe two or more commands or routines. In such cases, the manpage is usually named for the ®rst command or function that appears in the NAME section. Occasionally, a manpage name appears as a pre®x to the NAME section. In such instances, the name describes the commands or functions in more general terms. For example, the acct(1M) manpage describes the acctdisk, acctdusg, acc- ton, and acctwtmp commands, while the string(3C) manpage describes many character string functions.

The various sections are described as follows:

Volume Table of Contents (Printed Manual)

A complete listing of all manpages in the order they appear in each section, as well as alphabetically intermixed lists of all command, function, and feature names that are the different from the manpage where they appear

Section 1: User Commands

Programs that are usually invoked directly by users or from command language procedures (scripts).

Section 1M: System Administration Commands

Commands used for system installation and maintenance, including boot processes, crash recovery, system integrity testing, and other needs. Most commands in this section require the superuser privilege.
