目录下有这些文件
WindowsServer2003-KB901190-x86-CHS.exe
WindowsServer2003-KB908531-v2-x86-CHS.exe
WindowsServer2003-KB911280-v2-x86-CHS.exe
WindowsServer2003-KB911567-x86-CHS.exe
WindowsServer2003-KB911927-x86-CHS.exe

想用P处理改名为
KB901190.exe
KB908531.exe
KB911280.exe
KB911567.exe
KB911927.exe

放在KB目录内

@echo off

for /f "delims=" %%a in ('dir /a-d/b "*kb*.*" 2^>nul') do (

    for /f "tokens=2 delims=KB-" %%i in ('echo.%%a') do  ren %%~nxa KB%%~ni.*

)

pause

针对性定做的 放在同一目录下
@echo off&setlocal enabledelayedexpansion
for /f %%i in ('dir/b') do (
set a=%%i
ren "%%~fi" "!a:~18,10!.exe")
pause

请问一下tokens=2读取的是EXE吧？delims=KB-这里替换的什么？最后 %%~nxa KB%%~ni.* 参数的意思是？

多谢各位
