如何删除文件以子字符串结尾且早于N天 [英] How to delete files end with a substring and older than N days

问题描述

我想要delete个以_C结尾的7天之前的无扩展名文件.

I want to delete extensionless files older than 7 days whose names end with _C.

示例文件:

B_C_A1_C
B_C_A2_C
B_C_A3_A
test.txt 

我的代码:

SET mypath=%cd%\downloads
ForFiles /p %mypath% /d -7 /c "cmd /c del /q %mypath%\*_C

执行代码时，它会删除所有包含_C的文件，但是我只想删除以_C结尾且早于7天的文件.

When I execute the code, it deletes all files which contains _C, but I want to delete only files which end with _C and are older than 7 days.

我该如何解决?

推荐答案

有关批处理文件以删除N天之前的文件.

通配符表达式*_C选择任何以_C结尾的文件，而不管其是否具有扩展名.

The wildcard expression *_C selects any files which end with _C, regardless of whether it has an extension.

最终的代码非常复杂:

forfiles /p "%cd%" /m *_C /C "cmd /c \"echo @file^|find \".\" ^|^| del @path\""

使用*_C将选择以下内容:

anything without periods_C

它将不选择以下内容:

any.thing_C
anything.txt._C
anything containing periods_C
