Как искать определенные файлы из двух папок и сравнивать временные метки, если они совпадают, или какие самые новые файлы указаны с использованием пакетных сценариев Windows

Question

У меня есть исходный код для поиска и сравнения во ВСЕХ файлах:

SET FILE1=Directory1\* 
SET FILE2=Directory2\* 


FOR %%i IN (%FILE1%) DO SET DATE1=%%~ti
FOR %%i IN (%FILE2%) DO SET DATE2=%%~ti
IF "%DATE1%"=="%DATE2%" ECHO Files have same age && GOTO END

FOR /F %%i IN ('DIR /B /O:D %FILE1% %FILE2%') DO SET NEWEST=%%i
ECHO Newer file is %NEWEST%

:END

Как конкретно выполнить поиск по каталогу, что это определенное имя файла должно быть найдено и сравнено?

Образец: я хочу найти все конкретные, например, файлы INV и SLS, по его имени и сравнить, совпадает ли он с новым файлом:

в каталоге 1:

Flatfile           Timestamp
-------           ----------
INVF032            3/14/2019
INVF021            3/14/2019
KVNF234            3/14/2019
SLS0234            3/14/2019
SLS3211            3/14/2019

в каталоге 2:

Flatfile           Timestamp
-------           ----------
INVF032            3/19/2019
INVF021            3/19/2019
KVNF234            3/19/2019
SLS0234            3/19/2019
SLS3211            3/19/2019

Вывод:

Newer files is:
INVF032            3/19/2019
INVF021            3/19/2019
SLS0234            3/19/2019
SLS3211            3/19/2019

Добавление некоторого эха при ошибках в выводе после запуска в Windows Server 2008 (он говорит, что экземпляр недоступен):

Answer 1

Решение PowerShell, использующее для сравнения LastWriteTime.

$Dir1 = 'X:\Directory1\'
$Dir2 = 'X:\Directory2\'

ForEach ($File1 in (Get-ChildItem -Path $Dir1 -File | 
                    Where-Object Name -match "^(INV|SLS)")){
  $File2 = Join-Path $Dir2 $File1.Name
  If (Test-Path $File2 -NewerThan $File1.LastWriteTime){
    "File {0} is newer {1} in {2}" -f $File1.Name,(Get-Item $File2).LastWriteTime,$Dir2
  } else {
    "File {0} is newer {1} in {2}" -f $File1.Name,$File1.LastWriteTime,$Dir1 
  }
}

Пример вывода (с моим языковым стандартом формат даты / времени гггг-мм-дд ЧЧ: мм: сс):

File INVF021 is newer 2019-03-19 00:00:00 in X:\Directory2\
File INVF032 is newer 2019-03-19 00:00:00 in X:\Directory2\
File SLS0234 is newer 2019-03-19 00:00:00 in X:\Directory2\
File SLS3211 is newer 2019-03-19 00:00:00 in X:\Directory2\

Answer 2

Ваше намерение не совсем понятно, особенно потому, что желаемый вывод неоднозначен, поскольку он не содержит родительских каталогов файлов.

В любом случае, вот скрипт, который делает то, что вы хотите (по крайней мере длямое понимание), учитывая, что должны обрабатываться только файлы, присутствующие в обоих каталогах.

Так что это код, содержащий несколько пояснительных rem -маркиров:

@echo off
setlocal EnableExtensions DisableDelayedExpansion

rem // Define constants here:
set "_ROOT=%~dp0." & rem // (common root directory; `%~dp0.` is script's parent, `.` is current)
set "_DIR1=%_ROOT%\Directory1" & rem // (1st directory containing files)
set "_DIR2=%_ROOT%\Directory2" & rem // (2nd directory containing files)
set _MASKS="INV*." "SLS*."     & rem // (list of quoted file masks)
set "_TMP1=%TEMP%\%~n0_1_%RANDOM%.tmp" & rem // (1st temporary file)
set "_TMP2=%TEMP%\%~n0_2_%RANDOM%.tmp" & rem // (2nd temporary file)

rem // Resolve 1st directory to be an absolute path:
for %%E in ("%_DIR1%") do set "RDIR1=%%~fE"
rem // Resolve 2nd directory to be an absolute path:
for %%E in ("%_DIR2%") do set "RDIR2=%%~fE"

rem // Write all matching files in 1st directory to 1st temporary file:
pushd "%RDIR1%" && (
    for %%F in (%_MASKS%) do (
        echo(%%~nxF
    )
    popd
) > "%_TMP1%"
rem // Write all matching files in 2nd directory to 2nd temporary file:
pushd "%RDIR2%" && (
    for %%F in (%_MASKS%) do (
        echo(%%~nxF
    )
    popd
) > "%_TMP2%"

rem // Loop over all common files from both temporary files:
for /F %%L in ('findstr /L /I /X /G:"%_TMP1%" "%_TMP2%"') do (
    rem // Build absolute `wmic`-compatible file paths:
    set "FILE1=%RDIR1:\=\\%\\%%L" & set "FILE2=%RDIR2:\=\\%\\%%L"
    setlocal EnableDelayedExpansion
    rem set "FILE1=%!FILE1:&=&!" & set "FILE2=%!FILE2:&=&!"
    rem // Get standardised file date/time (last modification) of 1st file by `wmic`:
    for /F "skip=1" %%K in ('wmic DataFile where "Name='!FILE1!'" get LastModified') do for /F %%K in ("%%K") do set "DATE1=%%K"
    rem // Get standardised file date/time (last modification) of 2nd file by `wmic`:
    for /F "skip=1" %%K in ('wmic DataFile where "Name='!FILE2!'" get LastModified') do for /F %%K in ("%%K") do set "DATE2=%%K"
    rem // Compare file dates/times (last mod.) of both files and return differing ones:
    if !DATE1! leq !DATE2! echo "!FILE1:\\=\!" is older than "!FILE2:\\=\!"
    if !DATE1! gtr !DATE2! echo "!FILE1:\\=\!" is newer than "!FILE2:\\=\!"
    if !DATE1! equ !DATE2! echo "!FILE1:\\=\!" and "!FILE2:\\=\!" are of same age
    endlocal
)

rem // Clean up temporary files:
del "%_TMP1%" "%_TMP2%"

endlocal
exit /B

основные команды:

• findstr, чтобы вернуть все файлы, которые являются общими в двух указанных каталогах;
• wmic, чтобы получить дату / время последнего изменения файлов стандартным способом (отформатированный как YYYYMMDDhhmmss.uuuuuu+ZZZ), который можно легко сравнить как строки;
