一大堆学习过程中产生的临时脚本

一大堆学习过程中产生的临时脚本，涉及到搜索文件的功能、查询注册表或者执行systeminfo命令获取系统版本的功能，可以学习for的用法等。

@echo off
ipconfig /al >> log.txt 2>&1
pause
exit
rem 网友给的解决方案
for %%i in (c: d: e:) do (
pushd %%i
for /r %%j in (ospp.vbs) do if exist %%j echo %%j)
pause
exit

for %%i in (c: d: e: f:) do (
pushd %%i
dir /a-d /b /s ospp.vbs
)
pause
exit

FOR /F "tokens=1,2,* delims= " %%i in ('REG QUERY "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\Winword.exe" /v "Path"') do FOR /F "tokens=1-5 delims=\\" %%l in ("%%k") do echo %%o
echo %Name%

pause
exit

rem 行不通，闪退
for %%i in (c:\ d:\ e:\) do for /r %%i %%j in (ospp.vbs) do if exist %%j echo %%j
pause
exit

for /r c:\ %%i in (ospp.vbs) do if exist %%i echo %%i else echo none
pause
exit

FOR /F "tokens=1,2,* delims= " %%i in ('REG QUERY "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion" /v "ProductName"') do set Name=%%k
echo %Name%

goto Windows Server 2012 Datacenter
goto def

:Windows Server 2012 Datacenter
echo abc123
pause
exit

:def
echo def
pause
exit

rem 方法二，成功
FOR /F "tokens=1,* delims=:" %%i in ('systeminfo') do if {"%%i"}=={"OS 名称"} set Name=%%j
rem 清除字符串中所有空格
set "Name=%Name: =%"
echo %Name%
pause
exit
rem 方法三，成功
FOR /F "tokens=1,* delims=:" %%i in ('systeminfo') do (
  if {"%%i"}=={"OS 名称"} (
    for /f "tokens=*" %%k in ("%%j") do set "name=%%k"
  )
)
echo,%name%
pause>nul
exit
rem 方法一，成功
rem 第二个for为了清除截取到的字符串前面的空格
FOR /F "tokens=1,* delims=:" %%i in ('systeminfo') do if {"%%i"}=={"OS 名称"} for /f "tokens=* delims= " %%l in ("%%j") do set Name=%%l
echo %Name%
pause
exit
REG QUERY HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion | find /i "EFS" 1>nul
if ERRORLEVEL 1 echo error
echo succ
pause
exit
systeminfo 2>nul | find /i "Microsoft Windows Server 2012 Standard" && echo 成功地激活了产品。
systeminfo 2>nul | find /i "Microsoft Windows Server 2012 Datacenter" && echo 成功地激活了产品。
systeminfo 2>nul | find /i "Microsoft Windows Server 2012 R2 Datacenter" && echo 成功地激活了产品。
systeminfo 2>nul | find /i "Microsoft Windows 8 专业版" && echo 成功地激活了产品。
systeminfo 2>nul | find /i "Windows 8 Enterprise" && echo 成功地激活了产品。
