Find files on Windows modified after a given date using the command line
提问by Daniel Pe?alba
I need to search a file on my disk modified after a given date using the command line.
我需要使用命令行搜索在给定日期之后修改的磁盘上的文件。
For example:
例如：
dir /S /B WHERE modified date > 12/07/2013

The forfilescommand worked for me on Windows 7. The article is here:
该forfiles命令在 Windows 7 上对我有用。文章在这里：
Find files based on modified time
Microsoft Technet documentation: ForfilesFor the example above:
Microsoft Technet 文档：Forfiles对于上面的示例：
forfiles /P <dir> /S /D +12/07/2013
- /P The starting path to search
- /S Recurse into sub-directories
- /D Date to search, the "+" means "greater than" or "since"
- /P 搜索的起始路径
- /S 递归到子目录
- /D 要搜索的日期，“+”表示“大于”或“自”

You can use PowerShell to do this. Try:
您可以使用 PowerShell 执行此操作。尝试：
Get-ChildItem -Recurse | Where-Object { $_.LastWriteTime -ge "12/27/2016" }

I was after the size of the files changed and did not have PowerShell. I used the following, but the clue came from other posts:
我是在文件大小改变之后没有 PowerShell。我使用了以下内容，但线索来自其他帖子：
http://www.scotiasystems.com/blog/it-hints-and-tips/quick-way-to-find-recently-changed-files-in-windowsand Windows command for file size only
http://www.scotiasystems.com/blog/it-hints-and-tips/quick-way-to-find-recently-changed-files-in-windows和仅用于文件大小的 Windows 命令
set Target=E:\userdata
rem Date format is M-D-YYYY
set date=12-13-2013
set Filelist=d:\temp\filelist.txt
set Sizelist=d:\temp\sizelist%date%.csv
echo Target is %Target%
echo Start date is %date%
echo file list is %Filelist%
echo Sizelist is %sizelist%
Xcopy %Target% /D:%date% /L /S > %Filelist%
echo FileSize (bytes), FileName > %sizelist%
For /f "tokens=1 delims=;" %%j in (%Filelist%) do (
call :Size "%%j"
)
Goto :EOF
:Size
@echo off
echo %~z1, %1 >> %sizelist%

I had the same problem, so I created a list using XCOPY and the modified-by date I was looking for, used a forloop to traverse the list, and added the date/time information I needed for each file to a log:
我遇到了同样的问题，所以我使用 XCOPY 和我正在寻找的修改日期创建了一个列表，使用for循环遍历列表，并将每个文件所需的日期/时间信息添加到日志中：
xcopy X:\file_*.log X:\temp /D:07-17-2014 /L /Y > X:\files.txt
for /f "tokens=* delims=" %%a in (X:\files.txt ) do (
@echo %%~ta %%a >> X:\files.log
)
It resulted in something like the following, which is exactly what I wanted.
结果如下，这正是我想要的。
X:\>()
07/17/2014 09:41 AM X:\file_201407170600.log
X:\>()
07/17/2014 09:41 AM X:\file_201407170615.log
X:\>()
07/17/2014 09:23 AM X:\file_201407170630.log

You can search files modified after a given date using XCOPY as in this example, looking for files since last day of 2018:
您可以使用 XCOPY 搜索在给定日期之后修改的文件，如本例所示，查找自 2018 年最后一天以来的文件：
xcopy *.* c:\temp\*.* /D:12-31-2018 /L /S
In this example, you are in the directory where your search begins.
在此示例中，您位于搜索开始的目录中。
C:\temp*.* is only a syntax requisite, and nothing will be copied there.
C:\temp*.* 只是语法要求，不会复制任何内容。
/D:12-31-2018 specifies the files modified date you are looking for, including the specified date.
/D:12-31-2018 指定您要查找的文件修改日期，包括指定日期。
/L: Shows the filenames, including drive and path, also makes XCOPY do not copy any file.
/L：显示文件名，包括驱动器和路径，也使 XCOPY 不复制任何文件。
/S: Search in subdirectories.
/S: 在子目录中搜索。

If you decide to use PowerShell, this will also work with time and date ranges:
如果您决定使用 PowerShell，这也适用于时间和日期范围：
Get-ChildItem -Recurse | Where-Object {($_.LastWriteTime -ge "04/15/2018 20:00:00") -and ($
_.LastWriteTime -lt "04/15/2018 21:00:00")}
To use a programmatic date or a Locale agnostic date time:
要使用编程日期或区域设置不可知的日期时间：
Get-ChildItem -Recurse | Where-Object {($_.LastWriteTime -ge (new-object System.DateTime 2018, 1, 10, 12, 30, 00)) -and ($_.LastWriteTime -lt (new-object System.DateTime 2018, 1, 14, 12, 15, 59))}
Where date and time are entered in increasing time specificity order:
日期和时间以增加的时间特异性顺序输入的地方：
Year, Month, Day, Hour, Minute, Second
年、月、日、时、分、秒

I had a similar challenge. I used forfiles, however I noticed that it gave >= rather than just >. The input date was a variable, and so I didn't want to go through a bunch of hoops/loops to calculate date + 1 day(think about logic for last day of month or last day of year).
我也遇到过类似的挑战。我使用了forfiles，但是我注意到它给出了 >= 而不仅仅是 >。输入日期是一个变量，所以我不想通过一堆箍/循环来计算date + 1 day（想想一个月的最后一天或一年的最后一天的逻辑）。
I created a function that ran forfilesfor a particular date. That gives us all files with a modification date that is >= _date_. And for each file I check if the modification date is _date_, and print the output to a file if and only if it is not equal. That means the output file only has entries for files that are > _date_.
我创建了forfiles一个在特定日期运行的函数。这为我们提供了修改日期为>= _date_. 对于每个文件，我检查修改日期是否为_date_，并且当且仅当它不相等时才将输出打印到文件中。这意味着输出文件只有> _date_.
I can then check for existence of the output file to determine if any files in the current directory are greater than the input date. Moreover, if I wanted to know which files are newer, I can view the contents of the output file.
然后我可以检查输出文件是否存在，以确定当前目录中是否有任何文件大于输入日期。此外，如果我想知道哪些文件较新，我可以查看输出文件的内容。
Finally, my input was parsed from a file that used a date format of MM/DD/YYYY, meaning it would be 07/01/2019 for July first. However, the date from FORFILES does not use leading zeros so I need to translate by dropping leading zeros.
最后，我的输入是从使用 MM/DD/YYYY 日期格式的文件中解析出来的，这意味着 7 月第一天是 07/01/2019。但是，来自 FORFILES 的日期不使用前导零，因此我需要通过删除前导零来进行翻译。
My first attempt was to use /A thinking it drops the leading zeros. It doesn't it reads the value as octal -- don't repeat the mistake of my first attempt. So I just created a little helper function :getNum that drops leading zeros.
我的第一次尝试是使用 /A 认为它会删除前导零。它不会将值读取为八进制——不要重复我第一次尝试的错误。所以我刚刚创建了一个小辅助函数 :getNum 来删除前导零。
