Getting additional help with Unix
NC State provides several other sources of information on the Unix operating
system:
Using the manual pages
Tthere are reference pages detailing nearly every
aspect of the Unix operating system as well as many of the major programs
used at NC State. These reference pages are "manual pages," generally referred
to as "man pages."
Although information in the man pages is highly detailed, this online
reference is the best source for exhaustive information regarding specific
Unix commands. When someone suggests you look at the "man pages" they mean
you should read the online reference manual.
The xman program can display the complete reference
material for a command or program, or one-line summaries selected by keyword.
To view the entire manual type xman at the prompt.
To use the man command to find information on a particular
program or command, type
man [program or command name]
For example, typing man more will display the reference
pages for the text browser command more. The display should
resemble the following:
MORE(1) USER COMMANDS MORE(1)
NAME
more, page - browse or page through a text file
SYNOPSIS
more [ -cdflsu ] [ -lines ] [ +linenumber ] [ +/pattern ]
[ filename ... ]
page [ -cdflsu ] [ -lines ] [ +linenumber ] [ +/pattern ] [
filename ... ]
DESCRIPTION
more is a filter that displays the contents of a text file
on the terminal, one screenful at a time. It normally
pauses after each screenful, and prints --More-- at the bot-
tom of the screen. more provides a two-line overlap between
Searching the man pages by key word
To use the man command to search by keyword, returning a
list of one line summaries of each matched keyword which can then be looked
at more closely with the normal man command.
For example, typing man -k lpr displays several
one-line summaries of each command containing "lpr" somewhere in
them. The example usually results in the following:
mailprint (1) - filter to strip out mail message attachments
/ncsu/kaputnic/man/whatis: No such file or directory
/usr/afsws/man/whatis: No such file or directory
/usr/local/X11/man/whatis: No such file or directory
/usr/local/man/whatis: No such file or directory
lpr (1) - send a job to the printer
lprm (1) - remove jobs from the printer queue
You don't normally have to worry about the lines which contain the "No
such file or directory" messages. Notice, however, that there are
three commands which do fit the search pattern: mailprint, which
contains "lpr" in the middle of the word, and lpr and lprm,
which are print control commands.
Once you have a an idea of the commands that pertain to your keyword,
you should look up the full reference page for those commands to
see which are best suited to your needs and precisely how to use
them.
How to look at uninstalled man
pages
Many programs have man pages that are not installed and thus will not
be found when you use the man command (even with a
keyword search). Most of these programs have accompanying man pages
in their locker.
Use the nroff command to format these pages for
your screen.
For example, the xcalendar program is currently
(7/95) in the "bin" directory of the "goodies" locker. The man page
is in the "man/man1/" directory of the "goodies" locker. To see the
manual page on xcalendar, change to the directory
with the man page and type:
nroff -man xcalendar.1 | more
The command is piping the output of the nroff format
command through the more page display command.

Sysnews
The sysnews command displays news about recent developments
on the Unity system.

Guide to the Eos Computing Environment
Guide to the Eos Computing Environment at North Carolina State University by
Ellen McDaniel, while intended for Eos users, is a good introduction to the Unity
system. The manual is available in paper from the NC State Bookstores for under
twenty dollars. Also see the Online Guide to Eos and Unity Computing NCSU at http://www.eos.ncsu.edu/guide/.
