The NetBSD Operating System is a fully functional Open Source UNIX-like operating system derived from the University of California, Berkeley Networking Release 2 (Net/2), 4.4BSD-Lite, and 4.4BSD-Lite2 sources. NetBSD runs on 57 different system architectures (ports) across 15 distinct CPU families, and is being ported to more. The NetBSD 5.2.1 release contains complete binary releases for many different system architectures. (A few ports are not fully supported at this time and are thus not part of the binary distribution. Please see the NetBSD web site at http://www.NetBSD.org/ for information on them.)
NetBSD is a completely integrated system. In addition to its highly portable, high performance kernel, NetBSD features a complete set of user utilities, compilers for several languages, the X Window System, firewall software and numerous other tools, all accompanied by full source code.
NetBSD is a creation of the members of the Internet community. Without the unique cooperation and coordination the net makes possible, it's likely that NetBSD wouldn't exist.
The complete list of changes can be found in the CHANGES-5.2.1: http://ftp.NetBSD.org/pub/NetBSD/NetBSD-5.2.1/CHANGES-5.2.1 file in the top level directory of the NetBSD 5.2.1 release tree. An abbreviated list is as follows:

It should be considered as deprecated. Users are expected to not rely on it any more beyond this major release.
Further, at least version 3.1 of Xen will be required to run NetBSD as Dom0 or DomU.

In addition to the files and directories listed above, there is one directory per architecture, for each of the architectures for which NetBSD 5.2.1 has a binary distribution.
The source distribution sets can be found in subdirectories of the
source
subdirectory of the distribution tree.
They contain the complete sources to the system.
The source distribution sets are as follows:
config(1)
utility.
All the above source sets are located in the
source/sets
subdirectory of the distribution tree.
The source sets are distributed as compressed tar files.
Except for the
pkgsrc
set, which is traditionally unpacked into
/usr/pkgsrc
,
all sets may be unpacked into
/usr/src
with the command:
#
cd / ; tar -zxpf set_name.tgz
In each of the source distribution set directories, there are files which contain the checksums of the files in the directory:
MD5
SHA512
The SHA512 digest is safer, but MD5 checksums are provided so that a wider range of operating systems can check the integrity of the release files.

NetBSD maintains its own set of sources for the X Window System in order to assure tight integration and compatibility. These sources are based on XFree86 4.5.0. Binary sets for the X Window System are distributed with NetBSD. The sets are:
The acorn26 binary distribution sets are distributed as gzipped tar files
named with the extension
.tgz,
e.g.
base.tgz
.
The instructions given for extracting the source sets work equally
well for the binary sets, but it is worth noting that if you use that
method, the filenames stored in the sets are relative and therefore
the files are extracted
below the current directory.
Therefore, if you want to extract the binaries into your system, i.e.
replace the system binaries with them, you have to run the
tar -xzpf
command from the root directory (
/
) of your system.
There is a copy of the
NetBSD/acorn26
bootloader,
boot26,
in the
installation/misc
subdirectory.
This is a RISC OS relocatable module, and should have its file
type set to ffa (Module) once it's been copied to a RISC OS system.
NetBSD/acorn26 5.2.1 should support all common Acorn machines fitted with ARM2, ARM3 and ARM250 CPUs. This includes all Archimedes systems (except for the A500 and A680 prototypes), all R-series workstations, the BBC A3000, the A5000, A4, A3010, A3020 and A4000.
New machines (A5000, A4, A3010, A3020 and A4000) may support the following, but this is mostly untested
NetBSD/acorn26
uses the machine's ROM OS to boot, and hence depends slightly on it.
It's been tested with RISC OS 3.10 and RISC OS 3.11, and should work
with other versions of RISC OS as well.
It hasn't been tested with Arthur at all.
To boot NetBSD, you will need the bootloader (boot26) and the kernel you wish to boot on a RISC OS file system somewhere. boot26 can boot gzipped kernels, so there's no need to gunzip it.
Note that if you are installing or upgrading from writable media, it can be write-protected if you wish. These systems mount a root image from inside the kernel, and will not need to write to the media. If you booted from a floppy, the floppy disk may be removed from the drive after the system has booted.
Installation is supported from several media types, including:
The steps necessary to prepare the distribution sets for installation depend upon which installation medium you choose. The steps for the various media are outlined below.

split(1)
command, running e.g.
split -b 235k base.tgz base.
to split the
base.tgz
file from
acorn26/binary/sets
into files named
base.aa
,

,
and so on.
Repeat this for all
set_name.tgz
files, splitting them into

files.
Count the number of

files that make up the
distribution sets you want to install or upgrade.
You will need one sixth that number of 1.44 MB floppies.
Format all of the floppies with
MS-DOS.
Do
not
make any of them bootable
MS-DOS
floppies, i.e. don't use
format
/s
to format them.
(If the floppies are bootable, then the
MS-DOS
system files that make them bootable will take up some space, and you
won't be able to fit the distribution set parts on the disks.)
If you're using floppies that are formatted for
MS-DOS
by their manufacturers, they probably aren't bootable, and you can use
them out of the box.
Place all of the
set_name.
xx
files on the
MS-DOS
disks.
Once you have the files on MS-DOS disks, you can proceed to the next step in the installation or upgrade process. If you're installing NetBSD from scratch, go to the section on preparing your hard disk, below. If you're upgrading an existing installation, go directly to the section on upgrading.
204.152.190.15
and the IPv6 address is
2001:4f8:3:7:230:48ff:fec6:9aaa:21
(as of May, 2010).
Once you have this information, you can proceed to the next step in the installation or upgrade process. If you're installing NetBSD from scratch, go to the section on preparing your hard disk, below. If you're upgrading an existing installation, go directly to the section on upgrading.
/etc/exports
file on the NFS server and resetting its mount daemon (mountd).
(Both of these actions will probably require superuser
privileges on the server.)
You need to know the numeric IP address of the NFS server, and, if you don't have DHCP available on your network and the server is not on a network directly connected to the machine on which you're installing or upgrading NetBSD, you need to know the numeric IP address of the router closest to the NetBSD machine. Finally, you need to know the numeric IP address of the NetBSD machine itself.
Once the NFS server is set up properly and you have the information mentioned above, you can proceed to the next step in the installation or upgrade process. If you're installing NetBSD from scratch, go to the section on preparing your hard disk, below. If you're upgrading an existing installation, go directly to the section on upgrading.
If you're making the tape on a UNIX-like system, the easiest way to do so is probably something like:
#
tar -cf tape_device dist_directories
where
tape_device
is the name of the tape device that
describes the tape drive you're using; possibly
/dev/rst0
,
or something similar, but it will vary from system to system.
(If you can't figure it out, ask your system administrator.)
In the above example,
dist_directories
are the
distribution sets' directories, for the distribution sets you
wish to place on the tape.
For instance, to put the
kern-GENERIC, base, and etc
distributions on tape (in
order to do the absolute minimum installation to a new disk),
you would do the following:
#
cd .../NetBSD-5.2.1
#
cd acorn26/binary
#
tar -cf tape_device kern-GENERIC base etc
Once you have the files on the tape, you can proceed to the next step in the installation or upgrade process. If you're installing NetBSD from scratch, go to the section on preparing your hard disk, below. If you're upgrading an existing installation, go directly to the section on upgrading.
If you're planning on installing NetBSD/acorn26 on a hard disk, first make sure it's supported (see above). Then make sure there's nothing you want to keep on it, since NetBSD/acorn26's ability to share a hard disk with RISC OS is at best untested.
Alternatively,
NetBSD/acorn26
can be made to run diskless, getting all its file systems from an NFS server.
Using sysinst, installing NetBSD is a relatively easy process. Still, you should read this document and have it in hand when doing the installation process. This document tries to be a good guide to the installation, and as such, covers many details for the sake of completeness. Do not let this discourage you; the install program is not hard to use.
The following is a walk-through of the steps you will take while
getting
NetBSD
installed on your hard disk.
sysinst
is a menu driven
installation system that allows for some freedom in doing the
installation.
Sometimes, questions will be asked and in many cases
the default answer will be displayed in brackets
(``[ ]'')
after the question.
If you wish to stop the installation, you may press
CONTROL-C
at any time, but if you do, you'll have to begin the installation
process again from scratch by running the
/sysinst
program from the command prompt.
It is not necessary to reboot.
First, let's describe a quick install. The other sections of this document go into the installation procedure in more detail, but you may find that you do not need this. If you want detailed instructions, skip to the next section. This section describes a basic installation, using a CD-ROM install as an example.

root
and set a password for that account.
You are also advised to edit
/etc/rc.conf
to match your needs.
You may want to read the
boot messages, to notice your disk's name and capacity.
Its name will be something like
sd0
or
wd0
and the geometry will be
printed on a line that begins with its name.
As mentioned above, you may need your disk's geometry when creating
NetBSD's
partitions.
You will also need to know the name, to tell
sysinst
which disk to use.
The most important thing to know is that
wd0
is
NetBSD's
name for your first IDE disk,
wd1
the second, etc.
sd0
is your first SCSI disk,
sd1
the second, etc.
Once NetBSD has booted and printed all the boot messages, you will be presented with a welcome message and a main menu. It will also include instructions for using the menus.
If you do not intend to use networking during the installation, but you do want your machine to be configured for networking once it is installed, you should first go to the Utility menu and select the Configure network option. If you only want to temporarily use networking during the installation, you can specify these parameters later. If you are not using the Domain Name System (DNS), you can give an empty response when asked to provide a server.
To start the installation, select Install NetBSD to hard disk from the main menu.
The first thing is to identify the disk on which you want to
install
NetBSD.
sysinst
will report a list of disks it finds
and ask you for your selection.
You should see disk names like
wd0
,
wd1
,
sd0
or
sd1
.
The next step is to choose which distribution sets you wish to install. Options are provided for full, minimal, and custom installations. If you choose sets on your own, base, etc, and a kernel must be selected.
You will be asked if you want to use the entire disk or only part of the disk. If you decide to use the entire disk for NetBSD, sysinst will check for the presence of other operating systems and you will be asked to confirm that you want to overwrite these.
The partition table of the NetBSD part of a disk is called a disklabel. If your disk already has a disklabel written to it, you can choose Use existing partition sizes. Otherwise, select Set sizes of NetBSD partitions.
After you have chosen your partitions and their sizes (or if you opted to use the existing partitions), you will be presented with the layout of the NetBSD disklabel and given one more chance to change it. For each partition, you can set the type, offset and size, block and fragment size, and the mount point. The type that NetBSD uses for normal file storage is called 4.2BSD. A swap partition has a special type called swap. Some partitions in the disklabel have a fixed purpose.
a
/
)
b
c
d-h
e
is the partition mounted on
/usr
,
but this is historical practice and not a fixed value.
You will then be asked to name your disk's disklabel. The default response will be ok for most purposes. If you choose to name it something different, make sure the name is a single word and contains no special characters. You don't need to remember this name.
You are now at the point of no return. Nothing has been written to your disk yet, but if you confirm that you want to install NetBSD, your hard drive will be modified. If you are sure you want to proceed, select yes.
The install program will now label your disk and make the file systems you specified. The file systems will be initialized to contain NetBSD bootstrapping binaries and configuration files. You will see messages on your screen from the various NetBSD disk preparation tools that are running. There should be no errors in this section of the installation. If there are, restart from the beginning of the installation process. Otherwise, you can continue the installation program after pressing the return key.
The NetBSD distribution consists of a number of sets that come in the form of gzipped tarfiles. At this point, you will be presented with a menu which enables you to choose from one of the following methods of installing the sets. Some of these methods will first load the sets on your hard disk, others will extract the sets directly.
For all these methods, the first step is making the sets available for extraction, and then do the actual installation. The sets can be made available in a few different ways. The following sections describe each of those methods. After reading the one about the method you will be using, you can continue to the section labeled `Extracting the distribution sets'.
When installing from a CD-ROM, you will be asked to specify
the device name for your CD-ROM drive
(usually cd0
),
and the directory name on the CD-ROM where the distribution files are.
sysinst will then check if the files are indeed available in the specified location, and proceed to the actual extraction of the sets.
To be able to install using ftp, you first need to configure
your network setup if you haven't already done so.
sysinst
will do this for you, asking you
if you want to use DHCP.
If you do not use DHCP, you can enter network configuration
details yourself.
If you do not have DNS set up for the machine that you
are installing on, you can just press
RETURN
in answer to this question, and DNS will not be used.
You will also be asked to specify the host that you want to transfer the sets from, the directory on that host, the account name and password used to log into that host using ftp, and optionally a proxy server to use. If you did not set up DNS, you will need to specify an IP address instead of a hostname for the ftp server.
sysinst will proceed to transfer all the default set files from the remote site to your hard disk.
To be able to install using NFS, you first need to configure
your network setup if you haven't already done so.
sysinst
will do this for you, asking you
if you want to use DHCP.
If you do not use DHCP, you can enter network configuration
details yourself.
If you do not have DNS set up for the machine that you
are installing on, you can just press
RETURN
in answer to this question, and DNS will not be used.
You will also be asked to specify the host that you want to transfer the sets from and the directory on that host that the files are in. This directory should be mountable by the machine you are installing on, i.e., correctly exported to your machine.
If you did not set up DNS, you will need to specify an IP address instead of a hostname for the NFS server.
In order to install from a local file system, you will
need to specify the device that the file system resides
on
(for example sd1e
)
the type of the file system,
and the directory on the specified file system where the sets are located.
sysinst
will then check if it
can indeed access the sets at that location.
This option assumes that you have already done some preparation yourself. The sets should be located in a directory on a file system that is already accessible. sysinst will ask you for the name of this directory.
Before extraction begins, you can elect to watch the files being extracted; the name of each file that is extracted will be shown. This can slow down the installation process considerably on machines with slow graphics consoles or serial consoles. Alternatively, you can choose to see a progress bar. This is the preferred option as it shows progress without significantly slowing down the installation process.
After all the files have been extracted, the device node files will be created. If you have already configured networking, you will be asked if you want to use this configuration for normal operation. If so, these values will be installed in the network configuration files. The next menu will allow you to select the time zone that you're in, to make sure your clock has the right offset from UTC. Finally you will be asked to select a password encryption algorithm and can then set a password for the "root" account, to prevent the machine from coming up without access restrictions.
Congratulations, you have successfully installed NetBSD 5.2.1. You can now reboot the machine and boot NetBSD from hard disk.
Once you've got the operating system running, there are a few things you need to do in order to bring the system into a properly configured state. The most important steps are described below.
/etc/rc.conf
If you or the installation software haven't done any configuration of
/etc/rc.conf
(sysinst
usually will),
the system will drop you into single user mode on first reboot with the
message
/etc/rc.conf
is
not
configured.
Multiuser
boot
aborted.
and with the root file system
(/
)
mounted read-only.
When the system asks you to choose a shell, simply press
RETURN
to get to a
/bin/sh
prompt.
If you are asked for a terminal type, respond with
vt220
(or whatever is appropriate for your terminal type)
and press
RETURN
.
You may need to type one of the following commands to get your delete key
to work properly, depending on your keyboard:
#
stty erase '^h'
#
stty erase '^?'
At this point, you need to configure at least
one file in the
/etc
directory.
You will need to mount your root file system read/write with:
#
/sbin/mount -u -w /
Change to the
/etc
directory and take a look at the
/etc/rc.conf
file.
Modify it to your tastes, making sure that you set
rc_configured=YES
so that your changes will be enabled and a multi-user boot can
proceed.
Default values for the various programs can be found in
/etc/defaults/rc.conf
,
where some in-line documentation may be found.
More complete documentation can be found in
rc.conf(5)
.
When you have finished editing
/etc/rc.conf
,
type
exit
at the prompt to
leave the single-user shell and continue with the multi-user boot.
Other values that may need to be set in
/etc/rc.conf
for a networked environment are
hostname
and possibly
defaultroute.
You may also need to add an
ifconfig_int
for your
<int>
network interface,
along the lines of
ifconfig_ei0="inet
192.0.2.123
netmask
255.255.255.0"
or, if you have
myname.my.dom
in
/etc/hosts
:
ifconfig_ei0="inet
myname.my.dom
netmask
255.255.255.0"
To enable proper hostname resolution, you will also want to add an
/etc/resolv.conf
file or (if you are feeling a little more adventurous) run
named(8)
.
See
resolv.conf(5)
or
named(8)
for more information.
Instead of manually configuring network and naming service,
DHCP can be used by setting
dhclient=YES
in
/etc/rc.conf
.
Other files in
/etc
that may require modification or setting up include
/etc/mailer.conf
,
/etc/nsswitch.conf
,
and
/etc/wscons.conf
.
After reboot, you can log in as
root
at the login prompt.
Unless you've set a password in
sysinst,
there
is no initial password.
You should create an account for yourself (see below) and protect it and the
``root''
account with good passwords.
By default, root login from the network is disabled (even via
ssh(1)
).
One way to become root over the network is to log in as a different
user that belongs to group
``wheel''
(see
group(5)
)
and use
su(1)
to become root.
Use the
useradd(8)
command to add accounts to your system.
Do not
edit
/etc/passwd
directly! See
vipw(8)
and
pwd_mkdb(8)
if you want to edit the password database.
If you installed the X Window System, you may want to read the chapter about X in the NetBSD Guide: http://netbsd.org/docs/guide/en/chap-x.html
If you wish to install any of the software freely available for UNIX-like systems you are strongly advised to first check the NetBSD package system, pkgsrc. pkgsrc automatically handles any changes necessary to make the software run on NetBSD. This includes the retrieval and installation of any other packages on which the software may depend.
acorn26/5.2.1/All
subdir.
You can install them with the following commands under
sh(1)
:
# PKG_PATH=ftp://ftp.NetBSD.org/pub/pkgsrc/packages/NetBSD/acorn26/5.2.1/All # export PKG_PATH # pkg_add -v tcsh # pkg_add -v bash # pkg_add -v perl # pkg_add -v apache # pkg_add -v kde # pkg_add -v firefox ...
If you are using
csh(1)
then replace the first two lines with the following:
# setenv PKG_PATH ftp://ftp.NetBSD.org/pub/pkgsrc/packages/NetBSD/acorn26/5.2.1/All
/pub/pkgsrc
directory.
If you would like to use such mirrors, you could also try the
/pub/NetBSD/packages/current-packages/NetBSD/acorn26/5.2.1/All
directory, which may have the same contents.
The above commands will install the Tenex-csh and Bourne Again shells, the Perl programming language, Apache web server, KDE desktop environment and the Firefox web browser as well as all the packages they depend on.
pkg_add(1)
command will complain about a version mismatch of packages with a message
like the following:
Warning:
package
`foo'
was
built
for
a
different
version
of
the
OS:
NetBSD/i386
M.N
(pkg)
vs.
NetBSD/i386
5.2.1
(this
host)
,
/usr/pkgsrc
(though other locations work fine) with the commands:
#
cd /usr
#
tar -zxpf pkgsrc.tar.gz
After extracting, see the
doc/pkgsrc.txt
file in the extraction directory (e.g.,
/usr/pkgsrc/doc/pkgsrc.txt
)
for more information.
/etc/mail/aliases
to forward root mail to the right place.
Don't forget to run
newaliases(1)
afterwards.
/etc/postfix/main.cf
file will almost definitely need to be adjusted.
If you prefer a different MTA, then install it using
pkgsrc or by hand and adjust
/etc/mailer.conf
.
/etc/rc.local
to run any local daemons you use.
/etc
files are documented in section 5 of the manual; so just invoking
#
man 5 filename
is likely to give you more information on these files.
The easiest way to upgrade to NetBSD 5.2.1 is with binaries, and that is the method documented here.
To do the upgrade, you must have one form of boot media available.
You must also have at least the
base
and
kern
binary distribution sets available.
Finally, you must have sufficient disk space available to install the
new binaries.
Since files already installed on the system are overwritten in place,
you only need additional free space for files which weren't previously
installed or to account for growth of the sets between releases.
If you have a few megabytes free on each of your root
(/
)
and
/usr
partitions, you should have enough space.
Since upgrading involves replacing the kernel, boot blocks, and most of the system binaries, it has the potential to cause data loss. You are strongly advised to back up any important data on the NetBSD partition or on another operating system's partition on your disk before beginning the upgrade process.
The upgrade procedure
is similar to an installation, but without the hard disk partitioning.
sysinst
will attempt to merge the settings stored in your
/etc
directory with the new version of
NetBSD.
Also, file systems are checked before unpacking the sets.
Fetching the binary
sets is done in the same manner as the installation procedure;
refer to the installation part of the document for help.
After a new kernel has been copied to your hard disk, your
machine is a complete
NetBSD
5.2.1
system.
However, that doesn't mean that you're finished with the upgrade process.
You will probably want to update the set of device
nodes you have in
/dev
.
If you've changed the contents of
/dev
by hand, you will need to be careful about this, but if
not, you can just cd into
/dev
,
and run the command:
#
sh MAKEDEV all
Finally, you will want to delete old binaries that were part
of the version of
NetBSD
that you upgraded from and have since been removed from the
NetBSD
distribution.
Users upgrading from previous versions of NetBSD may wish to bear the following problems and compatibility issues in mind when upgrading to NetBSD 5.2.1.
If your port uses X.Org and you see messages from the X server indicating that no devices were found, you may need to run X -configure and update your existing xorg.conf to use the BusID line from the newly-generated config file.
Dual-head support for PC systems has become broken for many configurations with the update to xorg-server 1.6.x, which has removed the userland PCI configuration mechanism, and needs to rely upon the OS. We hope to correct this for future releases. Workaround: The only workaround is non-trivial and requires programming several PCI BAR registers as they previously were in NetBSD 5.0.
If you are updating to
NetBSD
5.2.1
without the aid of sysinst or postinstall and your port uses X.Org, be sure
to remove
/usr/X11R7/lib/X11/xkb/symbols/pc
before extracting the xbase set.
In the version of X.Org shipped with 5.0, this was a directory, but in more
recent X.Org versions it is a file.
pkg_install now depends on the pkgdb cache for automatic conflict detection. It is recommended to rebuild the cache with
#
pkg_admin rebuild
audit-packages.conf(5)
has been superseded by
pkg_install.conf(5)
.
The default configuration is the same.
Support for
pkg_view(1)
has been retired.
The functionality of
audit-packages(1)
and
download-vulnerability-list(1)
has moved into
pkg_admin(1)
.
However, wrapper scripts that handle the common use cases are provided.
The pthread libraries from previous versions of
NetBSD
require that the
sysctl(3)
node
kern.no_sa_support
be set to
0
.
This affects the following environments:
The 5.x kernel defaults to
0
for
kern.no_sa_support
,
which covers the first case.
However, please note that a full installation of 5.x
(either from scratch or through an upgrade)
will set
kern.no_sa_support
to 1 during the boot process.
This means that for the last two cases, you will have to manually set
kern.no_sa_support
to
0
,
using either the
sysctl(8)
command or through
sysctl.conf(5)
.
Note that sysinst will automatically invoke
postinstall fix
The following issues can generally be resolved by running postinstall with the etc set:
postinstall -s /path/to/etc.tgz check
postinstall -s /path/to/etc.tgz fix
Issues fixed by postinstall:
/etc
need upgrading.
These include:
/etc/defaults/*
/etc/mtree/*
/etc/daily
/etc/weekly
/etc/monthly
/etc/security
/etc/rc.subr
/etc/rc
/etc/rc.shutdown
/etc/rc.d/*
/etc/envsys.conf
The following issues need to be resolved manually:
postinstall -s /path/to/etc.tgz fix mailerconf
/etc/mailer.conf
file to use Postfix as the MTA. When using
sysinst
to upgrade the system, it will ask if you want this to be done.
Note that if you have a customized Sendmail setup, you need to set up Postfix in an equivalent way; there is no tool for automatic conversion of Sendmail configuration to a Postfix one.
Postfix will be started automatically when the system boots.
You may see messages like "$sendmail is not set properly" at boot.
You can suppress them by removing
/etc/rc.d/sendmail
and
/etc/rc.d/smmsp
.
Those files and other parts of sendmail configuration like files under
/usr/share/sendmail
are not removed by default
while upgrading for those who want to continue using sendmail from
outside the base system.
If you want to delete them,
postinstall
can be used:
postinstall -s /path/to/etc.tgz fix sendmail
The following issues can generally be resolved by running postinstall with the etc set:
postinstall -s /path/to/etc.tgz check
postinstall -s /path/to/etc.tgz fix
Issues fixed by postinstall:
/etc
need upgrading.
These include:
/etc/defaults/*
/etc/mtree/*
/etc/daily
/etc/weekly
/etc/monthly
/etc/security
/etc/rc.subr
/etc/rc
/etc/rc.shutdown
/etc/rc.d/*
/etc/envsys.conf
The following issues need to be resolved manually:
mount(8)
command now requires the
nosuid
and
nodev
options to be explicitly specified.
Previously, these options were automatically enforced even if they
were not explicitly specified.
Documentation is available if you installed the manual
distribution set.
Traditionally, the
``man pages''
(documentation) are denoted by
`name(section)
'.
Some examples of this are
intro(1)
,
man(1)
,
apropos(1)
,
passwd(1)
,
and
passwd(5)
.
The section numbers group the topics into several categories, but three are of primary interest: user commands are in section 1, file formats are in section 5, and administrative information is in section 8.
The man command is used to view the documentation on a topic, and is started by entering man [section] topic. The brackets [] around the section should not be entered, but rather indicate that the section is optional. If you don't ask for a particular section, the topic with the lowest numbered section name will be displayed. For instance, after logging in, enter
#
man passwd
to read the documentation for
passwd(1)
.
To view the documentation for
passwd(5)
,
enter
#
man 5 passwd
instead.
If you are unsure of what man page you are looking for, enter
#
apropos subject-word
where subject-word is your topic of interest; a list of possibly related man pages will be displayed.
