uname -- display system name information

DESCRIPTION

The uname command lets shell scripts and other programs determine configuration information about the machine upon which the KornShell is running.

You can use the major and minor version numbers, returned by the -r and -v options to determine precisely which version of Windows is running on the machine:

                Major   Minor
Windows 95        4       00
Windows 98        4       10
Windows ME        4       90

Windows NT        4       00
Windows 2000      5       00
Windows XP        5       01
Windows 2003      5       02

Options

-a

displays all fields (equivalent to -mnrsv).

-m

displays the CPU or machine type. Possible values include:

386      Intel 386
486      Intel 486
586      Intel Pentium
2200     Intel IA64
8664     x64 (AMD64/EM64T)

-n

displays the node name of this particular machine. The node name usually differentiates machines running at one location.

-r

displays the release (major version) number of the operating system.

-s

displays the name of the operating system. This is the default output, when no options are given. Operating system names are as follows:

Operating System	Name
Windows NT/2000/XP	`Windows_NT`
Windows 95	`Windows_95`
Windows 98	`Windows_98`
Windows Me	`Windows_ME`

-v

displays the version (minor version) number of the operating system.

uname displays the selected information in the following order:

<system name>   <nodename>   <release>     <version>     <machine>

EXAMPLES

This shell command changes the prompt to identify the computer location.

export PS1="`uname -n`$ "
