The Tru64 UNIX operating system provides an extensive set of reference
pages (also called man pages or manual pages), each of which describes one
topic, such as a command, function, or file.
This chapter discusses the reference
pages.
4.1 Reading Reference Pages On Line
You can use the
webman
utility to read the reference
pages on line using your Web browser, and print them by clicking on the browser's
Print menu.
Alternatively, you can use the
xman
or
man
utilities from the command line to read the reference pages.
Your system administrator determines at system installation time whether to make the operating system reference pages available on your system. If you receive an error message when you try to read reference pages, the problem might be that they are not installed.
Your system administrator also decides whether to install the reference
pages that are included with layered products.
This includes products such
as theTruCluster Server, which provides a full set of its own reference pages.
4.1.1 Using the Documentation CD-ROM
The Library on the Documentation CD-ROM includes a category that
contains the full set of base operating system reference pages in HTML form.
You can view these references pages with your Web browser just as you would
view any of the HTML books.
These references pages are indexed and hot-linked
with the books for easy access.
(The reference pages for layered products
are not included on this CD-ROM.)
4.1.2 Using webman
The
Documentation CD-ROM contains the
webman
viewer,
a UNIX CGI program you can use with your browser to view the reference pages
that are installed with the operating system.
The
webman
viewer is most useful when the Documentation CD-ROM is not mounted,
or when you need to access reference pages that have been installed with layered
applications.
For information about installing and using
webman,
see the following file on the Documentation CD-ROM:
/mount-point/DOCS/HTML/webman/Installing_webman.txt
See
Section 1.4.1
for information about the Documentation
CD-ROM.
4.1.3 Using the xman Command
The
xman
command starts an X Window System reference-page
browsing tool.
One of the functions of the tool is to display a list of
the reference pages.
You display a reference page by double-clicking on its
name in the list.
For more information about the
xman
command, start up the tool by entering the following command:
%xman &
The ampersand (&) runs the command in the background,
allowing the command line to be used for other tasks.
The application displays
a small window that contains three buttons.
Click on the Manual Page button
to read a reference page about the
xman
command.
4.1.4 Using the man Command
The
man
command displays the reference page specified
on the
man
command line.
For more information about the
man
command, read the
man(1)
reference page.
To display this reference
page, enter the following command:
%man man
4.2 Reading Reference Pages in Printed Books
Compaq provides a separately orderable Reference Pages Documentation Set. In this printed format, the Reference Page books are grouped according to their sections, each of which contains one or more volumes. The books contain an R on the spines to help you to quickly identify them as reference page books.
To order the Reference Page Kit, refer to Chapter 6.
Note
The Reference Page Kit is usually updated only with major releases of Tru64 UNIX. Therefore, the online reference pages provide more current information about features that are added or revised in minor releases.
The reference pages are grouped into sections, according to their function, audience, or both. The section numbers appear as numbers in parentheses next to the name of the reference page. For example:
lpr(1)automount(8)createlabel(3)
The following list describes the section numbers:
Reference Pages Section 1
Section 1 describes user commands that are available to everyone who uses the Tru64 UNIX operating system.
In printed form, this section is divided into five volumes.
Reference Pages Section 2
Section 2 defines system calls (entries into the Tru64 UNIX kernel)
that programmers use.
The introduction to Section 2,
intro(2), lists error
numbers with brief descriptions of their meanings.
The introduction also
defines many of the terms used in this section.
In printed form, this section is in one volume.
Reference Pages Section 3
Section 3 describes the routines available in Tru64 UNIX programming libraries, including the C library, Motif library, and X library. This section is for programmers.
In printed form, this section is divided into seven volumes.
Reference Pages Section 4
Section 4 describes the format of system files and how the files are used. The files described include assembler and link editor output, system accounting, and file system formats. This section is for programmers and system administrators.
In printed form, this section is divided into two volumes.
Reference Pages Section 5
Section 5 contains miscellaneous information, including ASCII character codes, mail-addressing formats, text-formatting macros, and a description of the root file system. This section is for programmers and system administrators.
In printed form, this section is divided into two volumes.
Reference Pages Section 7
Section 7 describes special files, related device driver functions, databases, and network support. This section is for programmers and system administrators.
In printed form, this section is in one volume.
Reference Pages Sections 8 and 1m
Sections 8 and 1m describe commands for system operation and maintenance. These sections are for system administrators.
In printed form, these sections are divided into three volumes.
Reference Pages Sections 9
Section 9 describes data structures and routines used in writing kernel modules. This section is for developers.
In printed form, this section is in one volume.
