我有没有产生什么,我会想到下面CMD脚本:CMD脚本问题与Delims

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%的被退回的“测试”,但我希望DIRNAME是“SandboxTest” 。

任何人有任何想法,为什么这是?我的分机有问题吗?

感谢, 基思

你想用变量引用语法。

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

delims是用来分裂

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 
    ) 

字符的阵列它分裂上的字符不是的话。

bcd 
fgh 
jklmn 
pqrst 
vwxyz 

类型for /?用于全范围的可变参考语法。

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

威廉,感谢您的输入。这就是我一直在寻找和你的解决方案工作!非常感激! -Keith – Keith 2013-03-07 20:33:09

DELIMS没有定义定界符短语 - 它定义了一组定界符字符的。 “测试”中没有任何字符出现在您的DELIMS设置中,因此是结果。

在你particluar引用情况下,可以使用得到你想要的结果:

for %%F in ("%child%") do set DIRNAME=%%~nxF 
+0

谢谢,dbenham。您的解决方案非常好它也很干净。 – Keith 2013-03-07 20:45:04
