【随笔】使用bat脚本判断操作系统

说明：

该脚本首先判断当前操作系统，然后判断该系统是32位还是64位系统，最后根据不同的系统执行不同命令。

@echo off

ver | find "6.1." > NUL &&  goto win7 
ver | find "10.0." > NUL &&  goto win10
goto end

:win7
if exist "c:agentinstalled.txt"   goto end
if not exist "c:agentinstalled.txt" goto first

:win10
if exist "c:agentinstalled.txt"   goto end
if not exist "c:agentinstalled.txt" goto second

:first
if  "%PROCESSOR_ARCHITECTURE%"=="AMD64" (
    
    echo      "first x64" > "c:agentinstalled.txt"
)^
else if "%PROCESSOR_ARCHITECTURE%"=="x86" (
    
    echo     " first x86"  > "c:agentinstalled.txt"
)
goto end


:second
if  "%PROCESSOR_ARCHITECTURE%"=="AMD64" (
    
    echo     "second x64" > "c:pagentinstalled.txt"
)^
else if "%PROCESSOR_ARCHITECTURE%"=="x86" (
    
    echo     "second x86  > "c:agentinstalled.txt"
)
goto end


:end
exit
