如何檢查給定的文件是否位於給定目錄下的任何位置通過命令行在Windows XP中？

Question

因此，例如我需要檢查文件C：\ windows \ system32 \ whatever.dll位於c：\ windows中。有沒有可能以if not exists ...的方式，但這裏if %file% lies in %directory%？

編輯：我知道我正在尋找的文件的路徑。問題歸結爲比較字符串，即檢查目錄的路徑是否包含在文件路徑的開頭。

Answer 1

，你可以這樣做

if not exists %directory%\%file% 

這樣你創建一個完整的文件路徑，如 「C：\ MyFolder文件\ yourfolder \ myfile.txt的」，並檢查它的存在

更新
這應該工作（但它未測試）

:: starting folder 
set RootPath=c:\myfolder\yourfolder\ 

::check all subfolder 
for /R "%RootPath%" %%d IN (.) DO ( 
    echo %%d 

    :: check all file in each subfolder 
    for %%f IN ("%%~d\*.*") DO (

     :: check if your file exist 
     IF "%%~nxf"=="filenameImLookingFor.txt" (
       echo Found file here "%%~f" 
     ) 
    ) 
) 

• %%〜NXF將拓展與延伸FILNAME，沒有路徑
• 的「〜」同時也要確保擴大的變量都不會包含 前綴/後綴doublequte，這樣您就可以添加自己的無需意想不到的雙重雙引號 （這將明顯地搞搞 高達）

這裏是一個變量有用的命令的列表（從的幫助下FOR命令）

您現在可以使用下列選項語法：

%~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 

的修飾符可以結合使用來得到多重結果：

%~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
