编写一个批处理文件，删除子目录的特定子目录中3年前的文件

Question

我正在为Windows 7编写批处理文件。

我目前有一个代码，可以从站点管理文件夹中的masters文件夹中删除旧备份。代码如下：

for /d %%A in ("Y:\*.*") do del /s /q /f "%%A\masters\*.bak"

但是，我需要将其编码为仅删除超过3年的内容，这将是以下代码：

forfiles /P "Y:\" /S /D -1096 /M *.bak /C "cmd /C del @path"

但是，我需要顶部代码中的内容，以便我可以从我们173个站点管理文件夹中存在的master文件夹中删除所有*. bak文件。我正在努力解决这个问题。我不能让它从我们的其他文件夹中删除*. bak文件。

我已尝试组合代码，但批处理文件中下面的命令行无法按预期工作：

forfiles /S /D -1096 /M *.bak /C "cmd /C for /d %%A in ("Y:\*.*") do del /s /q /f "%%A\masters\*.bak"

如何删除所有*。如果文件路径中的第二个目录是主目录，则在目录树中的任何位置保存3年以上的bak文件，并保留所有其他*。bak文件较新或位于文件路径中的第二个目录不是主目录的目录中？

伊姆古尔。com/a/isTOm这里是目录。由于我在驱动器上的权限，我无法进行转储，因此这是我所能做的最好的。

我如何使它从删除：|美国-美国|加拿大|GME|GMIO|GMSA|墨西哥|文件夹以及进展中的和MASTERS文件夹在这6个目录中的每一个是3岁或更老？

提前谢谢！！

@Mofi试图在这里帮助我，但在工作后他们更改了文件夹，MOFI建议我提出一个新问题，而不是编辑他自己的问题，如何根据文件路径中的目录递归删除比特定日期更旧的*. bak文件？给你。

Answer 1

据我所知，这项任务是：从路径为Masters的文件夹中删除所有旧文件。

使用dir /S /B获取所有文件夹的完整路径这将递归输出当前路径中所有文件夹的完整路径。

使用命令findstr/R/C筛选文件夹：“Y:\\[^\]*\\[^\]*\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\。它将只输出与reqexp匹配的路径。请注意双斜杠<代码>[^\]*\[^\]*\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\。要在批处理中使用，符号必须加倍，因为它是特殊的转义符号。

在找到的路径上对文件执行

从示意图上看

for /f "delims=" %%f in ('dir masters /S /B ^| findstr /R /C:"Y:\\[^^\\]*\\[^^\\]*\\masters$"') do (
  :: %%f contains full path to "masters" folder
  forfiles ... 
)

我使用了文档。txt和以下批处理代码，用于测试批处理文件顶部的代码：

@echo off
if "%~1" == "#Delete:Backup#" (
    for /F "tokens=4 delims=\" %%I in ("%~2") do (
        if /I "%%I" == "masters" (
            ECHO del from line %Line%: "%~2"
        ) else if /I "%%I" == "wip" (
            ECHO del from line %Line%: "%~2"
        )
    )
    goto :EOF
)

set "Line=1"
for /F "delims=" %%# in (Document.txt) do (
    call "%~f0" #Delete:Backup# "%%#"
    set /A Line+=1
)

输出用于文档中的1219行。txt文件：

这看起来很正确，因此要使用的代码是：

@echo off
if "%~1" == "#Delete:Backup#" (
    for /F "tokens=4 delims=\" %%I in ("%~2") do (
        if /I "%%I" == "masters" (
            del "%~2"
        ) else if /I "%%I" == "wip" (
            del "%~2"
        )
    )
    goto :EOF
)

rem Other commands processing the parameters.

%SystemRoot%\System32\forfiles.exe /P "Y:\" /S /D -1096 /M *.bak /C "%~f0 #Delete:Backup# @PATH"

rem More commands executed after the deletion of the backup files.

然后我认为您将来可能会添加额外的目录，因此比这更好的代码结构将有助于您添加额外的目录。所以我想了一点，并在修改后的版本后再次测试，首先使用Documen.txt和1219*. bak文件名与完整路径。

@echo off
if "%~1" == "#Delete:Backup#" (
    for /F "tokens=4 delims=\" %%I in ("%~2") do (
        for %%J in (masters wip) do if /I "%%I" == "%%~J" ECHO del from line %Line%: "%~2" & goto :EOF
    )
    goto :EOF
)

set "Line=1"
for /F "delims=" %%# in (Document.txt) do (
    call "%~f0" #Delete:Backup# "%%#"
    set /A Line+=1
)

此代码产生的输出与第一个代码完全相同。因此，您还可以使用：

@echo off
if "%~1" == "#Delete:Backup#" (
    for /F "tokens=4 delims=\" %%I in ("%~2") do (
        for %%J in (masters wip) do if /I "%%I" == "%%~J" del "%~2" & goto :EOF
    )
    goto :EOF
)

rem Other commands processing the parameters.

%SystemRoot%\System32\forfiles.exe /P "Y:\" /S /D -1096 /M *.bak /C "%~f0 #Delete:Backup# @PATH"

rem More commands executed after the deletion of the backup files.

第三目录级别的其他目录可以通过master wip轻松添加。
