UNIX System Information

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 $ uname -a SunOS hieracium 5.6 Generic_105181-03 sun4m sparc sun4m

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

OS: IRIX

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

% uname -R 6.5 6.5.11m % uname -aR IRIX alnus 6.5 6.5.11m 01101246 IP32

OS: Linux

A more complete operating system version string can be found in /proc/version: $ 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

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

An alternative method is to use one of the [Standard Base] tools lsb_release: $ lsb_release -a LSB Version: 1.2 Distributor ID: Mandrake Description: Mandrake Linux Release: 9.0 Codename: dolphin

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: $ uname -a OSF1 laurus.woods V5.1 2650 alpha

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

The currently installed software packages can be listed with setld: $ /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)

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.

$ vmstat

HW: IRIX

On IRIX the hinv command provides a description of the current hardware configuration: % hinv CPU: MIPS R10000 Processor Chip Revision: 2.7 FPU: MIPS R10010 Floating Point Chip Revision: 0.0 1 195 MHZ IP32 Processor Main memory size: 640 Mbytes Secondary unified instruction/data cache size: 1 Mbyte on Processor 0 Instruction cache size: 32 Kbytes Data cache size: 32 Kbytes FLASH PROM version 4.16 Integral SCSI controller 0: Version ADAPTEC 7880
