Question

{ 设置File1 = C：\ filepath

设置File2 = C：\ filepath

FOR％i IN（％FILE1％）DO SET DATE1 = %% ~ti \

FOR％i IN（％FILE2％）DO SET DATE2 = %%〜ti

如果“％DATE1％”GTR“％DATE2％”ECHO文件具有相同的年龄＆amp;＆amp; GOTO END

FOR％i IN（'DIR / B / O：D“％FILE1％”“％FILE2％”'）DO SET NEWEST = %% i

ECHO较新的文件是“％NEWEST％”

Answer 1

试试这个：

@echo off
rem --compares the age of two files
rem --by Vasil "npocmaka" Arnaudov

call :isOlder     "C:\test.file1" "C:\test.file2"

goto :eof

:isOlder [%1 path to first file ; %2 path to second file]
    setlocal
        call :get_file_c_time  "%~1" time1
        call :get_file_c_time  "%~2" time2
    if "%time1%" LEQ "%time2%"  (
          echo YES
         ) else (
          echo NO
         )
goto :eof

:get_file_c_time [ %1 path to file; %2 variable to assign value  ]
        set file_path=%~1

        if not exist "%file_path%" echo file %1 does not exist&& exit /b 1

        if "%~2" equ "" echo need a secont parameter && exit /b 2

        setlocal enableDelayedExpansion

        for /f "skip=5 tokens=1,2,3,4,5,6 delims=/:.гчЈз " %%T in ('dir /tc "%file_path%"') do (
         if "%%Y" EQU "PM" (
          set /a "hour=%%W+12"
         ) else (
                set hour=%%W
         )
         set ftime=%%V%%U%%T!hour!%%Y
         goto :endfor
        )
:endfor

endlocal & set "%~2=%ftime%"
goto :eof

这取决于时间设置，但在大多数情况下应该工作.. 另一种方法是使用WMIC / WMI，但我需要一些时间来创建脚本

比较dos中的两个文件日期
