How can one determine what version of Windows and/or cmd.exe a batch file is running on?
There is no cmd /version that I ve been able to find and the results of SET in a command prompt session don t give anything obviously unique (between XP and Win7 anyway).
The version of cmd.exe should actually be pretty irrelevant, unless you try to use features that didn t exist before (in command.com for example). There is the pseudovariable
%cmdextversion%
which holds the version of the command extensions which has been 2 for ages (at least back to NT 4, iirc).
But, back to the point: Running ver and parsing the version string might be your best bet:
for /f "tokens=2 delims=[]" %%x in ( ver ) do set WINVER=%%x
set WINVER=%WINVER:Version =%
you can use the "systeminfo" @ cmd.exe
C:UsersTagon8>systeminfo | findstr /B /C:"OS Name" /C:"OS Version"
OS Name: Microsoft Windows 8 Release Preview
OS Version: 6.2.8400 N/A Build 8400
I found a shorter way using ver as well:
Could be even shorter:
ver | find "5.1" >nul && goto ver_winxp
Type "ver" at a command prompt.
Next time around, since this isn t really programming related but server or user related, you might try serverfault.com or superuser.com.
I found a shorter way using ver as well:
...
ver | find "5.1"
if %ERRORLEVEL% == 0 goto ver_winxp
...
This will find XP, replace the string with your wanted versions
To find the windows version using WMIC you can use:
wmic os get version
Maybe someone will need the following to determine the SKU (Win7). I m using some of this script to pick the right OS and XML during sysprep. Hope it helps!
@echo off
set ver=Unknown
systeminfo > C:sysinfo
findstr /e /c:"Enterprise " C:sysinfo 1>nul 2>nul
if %errorlevel% equ 0 set ver=Enterprise
findstr /e /c:"Ultimate " C:sysinfo 1>nul 2>nul
if %errorlevel% equ 0 set ver=Ultimate
findstr /e /c:"Professional " C:sysinfo 1>nul 2>nul
if %errorlevel% equ 0 set ver=Professional
findstr /e /c:"Home Premium " C:sysinfo 1>nul 2>nul
if %errorlevel% equ 0 set ver=Home Premium
findstr /e /c:"Home Basic " C:sysinfo 1>nul 2>nul
if %errorlevel% equ 0 set ver=Home Basic
del /f /q C:SPsysinfo 1>nul 2>nul
Echo Windows 7 %ver%
pause
exit
The internal command ver reports windows version number (which could have been learned by typing help at the command prompt).
There is a dynamic variable %CMDEXTVERSION%, but it hasn t progressed in several releases so it s only useful for delineating between Windows NT and Windows 2000 and newer. (Thanks @Joey, here.)
Here s a batch to parse the output of ver for XP and newer, courtesy of Simon Sheppard:
@echo off
Setlocal
:: Get windows Version numbers
For /f "tokens=2 delims=[]" %%G in ( ver ) Do (set _version=%%G)
For /f "tokens=2,3,4 delims=. " %%G in ( echo %_version% ) Do (set _major=%%G& set _minor=%%H& set _build=%%I)
Echo Major version: %_major% Minor Version: %_minor%.%_build%
if "%_major%"=="5" goto sub5
if "%_major%"=="6" goto sub6
Echo unsupported version
goto:eof
:sub5
::Winxp or 2003
if "%_minor%"=="2" goto sub_2003
Echo Windows XP [%PROCESSOR_ARCHITECTURE%]
goto:eof
:sub_2003
Echo Windows 2003 or xp 64 bit [%PROCESSOR_ARCHITECTURE%]
goto:eof
:sub6
if "%_minor%"=="1" goto sub7
Echo Windows Vista or Windows 2008 [%PROCESSOR_ARCHITECTURE%]
goto:eof
:sub7
Echo Windows 7 or Windows 2008 R2 [%PROCESSOR_ARCHITECTURE%]
goto:eof
And here s my own fairly complete, largely academic, kick at the can which returns the parsed version number as environment variables:
