===== Operating System Information =====

==== OS: Generic ====

On all UNIX and UNIX-like systems the ''uname'' command can be used to get some information about the operating system and platform. The simplest usage is to display all the information available. For example:

Sun Solaris 2.6
<code>
$ uname -a
SunOS hieracium 5.6 Generic_105181-03 sun4m sparc sun4m
</code>

Microsoft Windows XP system under Cygwin:
<code>
$ uname -a
CYGWIN_NT-5.1 salix 1.5.3(0.90/3/2) 2003-09-01 13:15 i686 unknown unknown Cygwin
</code>

==== OS: IRIX ====

On IRIX systems ''uname'' supports an extra option to give a more readable form of the operating system revision:

<code>
% uname -R
6.5 6.5.11m
% uname -aR
IRIX alnus 6.5 6.5.11m 01101246 IP32
</code>

==== OS: Linux ====

A more complete operating system version string can be found in ''/proc/version'':
<code>
$ cat /proc/version
Linux version 2.4.21-0.33mdkenterprise (qateam@updates.mandrakesoft.com) (gcc version 3.2.2 (Mandrake Linux 9.1 3.2.2-3mdk)) #1 SMP Wed Aug 11 10:09:17 MDT 2004
</code>

On many distributions the name and version of the distribution can be found in ''/etc/redhat-release'':
<code>
$ cat /etc/redhat-release
Mandrake Linux release 9.1 (Bamboo) for i586
</code>

An alternative method is to use one of the [[http://www.linuxbase.org/|Linux Standard Base]] tools ''lsb_release'':
<code>
$ lsb_release -a
LSB Version:    1.2
Distributor ID: Mandrake
Description:    Mandrake Linux
Release:        9.0
Codename:       dolphin
</code>

==== OS: OSF/1, Digital UNIX, Tru64 ====

On OSF/1 the ''uname'' command provides all the information required to figure out the operating system version but only if you can interpret the version numbers:
<code>
$ uname -a
OSF1 laurus.woods V5.1 2650 alpha
</code>

To get the version string displayed on start-up, which includes the official version number, use ''sizer -v'' instead:
<code>
$ sizer -v
Compaq Tru64 UNIX V5.1B (Rev. 2650); Sun Mar 20 06:36:49 GMT 2005
</code>

The currently installed software packages can be listed with ''setld'':
<code>
$ /usr/sbin/setld -i
Subset               Status                 Description
------               ------                 -----------
OSFACCT540           installed              System Accounting Utilities (System Administration)
OSFADVFS540          installed              AdvFS Commands (System Administration)
OSFADVFSBIN540       installed              AdvFS Kernel Modules (Kernel Build Environment)
...
OSFXPRT540           installed              Print X Server (Windows Applications)
OSFXSYSMAN540        installed              Graphical Base System Management Utilities(System Administration)
OSFXVFB540           installed              Virtual X Frame Buffer (Windows Applications)
</code>

===== Hardware Information =====

==== HW: Generic ====

On most UNIX systems the system log contains information about hardware detection. This is usually logged to ''/var/log/messages''. On some systems the ''dmesg'' command can be used to get this information, as a normal user.

=== Virtual Memory ===

To get information on virtual memory use the ''vmstat'' command.

<code>
$ vmstat
 procs     memory            page            disk          faults      cpu
 r b w   swap  free  re  mf pi po fr de sr f0 s0 s3 --   in   sy   cs us sy id
 0 0 0 268512  4968   2  27 50 50 60  0  4  0  0 10  0   41  562   36 78  3 19
</code>

==== HW: IRIX ====

On IRIX the ''hinv'' command provides a description of the current hardware configuration:
<code>
% hinv

</code>

==== HW: Linux ====

The ''/proc'' filesystem contains various files that can be used to obtain information about the hardware present in a system.

=== HW: Linux: CPU ===

<code>

This a not a description of the processor, but instead describes the mainboard type. In this case the machine is a AplhaPC 164LX which is a sub-type of the EB164 class of machines.
