CMD腳本問題與Delims

我有沒有產生什麼，我會想到下面CMD腳本：CMD腳本問題與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「測試」，但我希望DIRNAME是「SandboxTest」。

任何人有任何想法，爲什麼這是？我的分機有問題嗎？

感謝，基思

你想用變量引用語法。

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

delims是用來分裂

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 
    )

字符的陣列它分裂上的字符不是的話。

bcd 
fgh 
jklmn 
pqrst 
vwxyz

類型for /?用於全範圍的可變參考語法。

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，感謝您的輸入。這就是我一直在尋找和你的解決方案工作！非常感激！ -Keith – Keith 2013-03-07 20:33:09

DELIMS沒有定義定界符短語 - 它定義了一組定界符字符的。「測試」中沒有任何字符出現在您的DELIMS設置中，因此是結果。

在你particluar引用情況下，可以使用得到你想要的結果：

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