错误“\..此时出乎意料”

Question

我用它创建了一个 .reg 以在我的上下文菜单中添加一个 Delete empty folders 命令。当我右键单击一个文件夹时，这应该会删除它的空子文件夹。

我的上下文菜单中有 "Delete empty folders"，但是当我 select 这个时，一个 cmd windows 打开，我得到这个错误：.. 此时是意外的。知道为什么吗？

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Directory\shell\Delete empty folders]

[HKEY_CLASSES_ROOT\Directory\shell\Delete empty folders\Command]
@="cmd /c for /f \"usebackq delims=\" %%d in (`\"dir \"%1\" /ad/b/s | sort /R\"`) do rd \"%%d\""

代码来自@mmj (here)

编辑：感谢 JosephZ 的帮助，这里是解决方案：

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Directory\shell\Delete empty folders]

[HKEY_CLASSES_ROOT\Directory\shell\Delete empty folders\Command]
@="cmd.exe /K for /f \"usebackq delims=\" %%d in (`\"dir \"%V\" /ad/b/s | sort /R\"`) do rd \"%%~d\""

Answer 1

dir 命令解析为

`"dir "%1" /ad/b/s | sort /R"`

但应该解析为

`dir "%1" /ad/b/s | sort /R`

所以应该是

 `dir \"%1\" /ad/b/s | sort /R`

更新：如果您有批处理工作，为什么不从上下文菜单中调用它？

Answer 2

我不明白为什么您的代码会失败。出于调试目的：接下来的两个 .reg 工作：

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Directory\shell\List all subfolders2]

[HKEY_CLASSES_ROOT\Directory\shell\List all subfolders2\command]
@="cmd.exe /K for /f \"usebackq delims=\" %%d in (`\"dir \"%V\" /ad/b/s | sort /R\"`) do @echo \"%%~d\""

对您的代码所做的更改：

cmd.exe 而不是 cmd;
/K 切换以保持命令提示符 window 打开；
%V 而不是 %1 但也可以使用 %1；
@echo 而不是 rd 因为我不想删除任何目录，即使目录是空的（仅用于调试）；
%%~d 而不是 %%d.

另一种转义方式：

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Directory\shell\List all subfolders]

[HKEY_CLASSES_ROOT\Directory\shell\List all subfolders\command]
@="cmd.exe /S /K \"for /f \"delims=\" %%d in ('dir \"%V\" /ad/b/s ^| sort /R') do @echo \"%%~d\"\""

摘自cmd /?：

If /C or /K is specified, then the remainder of the command line after the switch is processed as a command line, where the following logic is used to process quote (") characters:

If all of the following conditions are met, then quote character on the command line are preserved:

no /S switch

exactly two quote characters

no special characters between the two quote characters, where special is one of: &<>()@^|

there are one or more whitespace characters between the two quote characters

the string between the two quote characters is the name of an executable file.

Otherwise, old behavior is to see if the first character is a quote character and if so, strip the leading character and remove the last quote character on the command line, preserving any text after the last quote character.

编辑：解决方案（OP Arone 一次又一次地建议）：

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Directory\shell\Delete empty folders]

[HKEY_CLASSES_ROOT\Directory\shell\Delete empty folders\Command]
@="cmd.exe /K for /f \"usebackq delims=\" %%d in (`\"dir \"%V\" /ad/b/s | sort /R\"`) do rd \"%%~d\""
