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 Server 2003     5       02
Windows Server 2003 R2  5       02
Windows Vista           6       00
Windows Server 2008     6       00
Windows 7               6       01
Windows Server 2008 R2  6       01
Windows 8               6       02
Windows Server 2012     6       02
Windows 8.1             6       03
Windows Server 2012 R2  6       03
Windows 10             10       00
Windows Server 2016    10       00
Windows Server 2019    10       00
Windows 11             10       00
Windows Server 2022    10       00

Options

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. The operating system name is Windows_NT for all supported platforms.

uname displays the selected information in the following order:

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