如果我们不想在指定日期之后复制文件,有人可以告诉我是否有任何方法。 例如。如果我指定日期2017年5月10日& 2017年5月11日,文件夹包含10& 2017年5月11日。所以如果只想复制10-MAY-2017文件。有什么办法吗?

对于手头的任务,robocopy
是最简单的方法:
robocopy D:\Source D:\Destination *.* /S /MINAGE:20170510
尽管名称为/MINAGE
,但不是创建,而是考虑最后修改日期。
如果您坚持使用xcopy
,则此处是基于xcopy
的脚本,执行以下步骤:
xcopy /L /F /D:
:/L
表示列出但不复制,/F
定义输出完全解析的源和目标路径,/D:
定义最后修改日期; xcopy /L /F
过滤掉所有可用文件(findstr
)列表中的所有文件; xcopy /T
); copy
; 这是代码:
@echo off
setlocal EnableExtensions DisableDelayedExpansion
rem // Define constants here:
set "SOURCE=D:\Source" & rem // (source directory)
set "DESTIN=D:\Destination" & rem // (target directory)
set "PATTERN=*.*" & rem // (file pattern)
set "COPYDATE=05-11-2017" & rem /* (last modification date; only files are copied
rem which are modified earlier; check format!) */
set "TEMPFILE=%TEMP%\%~n0_%RANDOM%.tmp" & rem // (list of source files not to copy)
set "COPYLIST=%TEMP%\%~n0_%RANDOM%.lst" & rem // (full list of files to copy)
rem // List files modified on or after given date:
> "%TEMPFILE%" (
for /F "tokens=1 delims=>" %%F in ('
xcopy /L /I /F /D:%COPYDATE% "%SOURCE%\%PATTERN%" "%DESTIN%" ^| find ":"
') do (
set "FILE=%%F"
rem /* Double every `\` as `findstr` uses such as escape character;
rem then append ` -> ` which is used by `xcopy /F` as separator: */
setlocal EnableDelayedExpansion
(echo(!FILE:\=\\!^> )
endlocal
)
)
rem /* List files modified before given date
rem (actually the temporary `%COPYLIST%` file is not really necessary,
rem but it is quite convenient for understanding what is going on; instead
rem the below `for /F` loop could parse the output of this command line): */
xcopy /L /I /F "%SOURCE%\%PATTERN%" "%DESTIN%" | find ":" ^
| findstr /V /B /L /I /G:"%TEMPFILE%" > "%COPYLIST%"
rem // Prepare directory tree as `copy` (below) cannot create directories:
xcopy /I /T "%SOURCE%\%PATTERN%" "%DESTIN%" > nul
rem // Copy files from list:
for /F "usebackq tokens=1* delims=>" %%E in ("%COPYLIST%") do (
set "LEFT=%%E" & set "RIGHT=%%F"
setlocal EnableDelayedExpansion
ECHO copy /Y "!LEFT:~,-2!" "!RIGHT:~1!"
endlocal
)
rem // Clean up temporary files:
del "%TEMPFILE%" "%COPYLIST%"
endlocal
exit /B

/ D:mm-dd-yyyy复制文件在指定日期或之后更改。如果没有给出日期,则仅复制源日期/时间早于目的地时间的文件。
示例:xcopy / D:mm-dd-yyy
