Delims的CMD脚本问题

我有下面的cmd脚本，它不能产生我所期望的结果：

set parent=src\Sandbox
set child=src\Sandbox\SandboxTest
echo %parent%
for /F "tokens=* delims=%parent%\" %%i in ("%child%") do set DIRNAME=%%i
echo %DIRNAME%

%DIRNAME%将作为“Test”返回，但我希望DIRNAME是“SandboxTest”

有人知道这是为什么吗？我的熟食有问题吗

谢谢，

您想使用变量引用语法

set parent=src\Sandbox
set child=src\Sandbox\SandboxTest
echo %parent%
for /F %%i in ("%child%") do (
    set DIRNAME=%%~ni
    )

In addition, substitution of FOR variable references has been enhanced.
You can now use the following optional syntax:

    %~I         - expands %I removing any surrounding quotes (")
    %~fI        - expands %I to a fully qualified path name
    %~dI        - expands %I to a drive letter only
    %~pI        - expands %I to a path only
    %~nI        - expands %I to a file name only
    %~xI        - expands %I to a file extension only
    %~sI        - expanded path contains short names only
    %~aI        - expands %I to file attributes of file
    %~tI        - expands %I to date/time of file
    %~zI        - expands %I to size of file
    %~$PATH:I   - searches the directories listed in the PATH
                   environment variable and expands %I to the
                   fully qualified name of the first one found.
                   If the environment variable name is not
                   defined or the file is not found by the
                   search, then this modifier expands to the
                   empty string

The modifiers can be combined to get compound results:

    %~dpI       - expands %I to a drive letter and path only
    %~nxI       - expands %I to a file name and extension only
    %~fsI       - expands %I to a full path name with short names only
    %~dp$PATH:I - searches the directories listed in the PATH
                   environment variable for %I and expands to the
                   drive letter and path of the first one found.
    %~ftzaI     - expands %I to a DIR like output line

delims是用于拆分的字符数组

set parent=aeiou
set child=abcdefghijklmnopqrstuvwxyz
for /F "tokens=1-10 delims=%parent%\" %%a in ("%child%") do (
    echo.%%a
    echo.%%b
    echo.%%c
    echo.%%d
    echo.%%e
    )

它根据字符而不是文字进行拆分

bcd
fgh
jklmn
pqrst
vwxyz

键入

以获取/？

以获取变量引用语法的完整范围

set parent=src\Sandbox
set child=src\Sandbox\SandboxTest
echo %parent%
for /F %%i in ("%child%") do (
    set DIRNAME=%%~ni
    )

DELIMS不定义delimeter短语-它定义一组分隔符字符。“Test”中的任何字符都不会出现在DELIMS集合中，因此会产生结果

在您引用的特定案例中，您可以使用以下方法获得所需的结果：

for %%F in ("%child%") do set DIRNAME=%%~nxF
