批量啓動路徑\此文件的文件名稱

Question

標題有點含糊，我不知道如何說出它。

我該怎麼做。 運行文件的開始路徑\文件名。

有點像啓動路徑\％0這是有點什麼，我正在嘗試做，但如果我這樣做，它會拿出像波紋管的東西。

複製C：\ Users \用戶名\桌面\文件夾\ C：\ Users \用戶名\桌面\ batch.bat

我只想C：\ Users \用戶名\桌面\文件夾\ batch.bat batch.bat是文件名，如果你重命名批處理文件，這個必須改變。

對不起，如果我解釋得很糟糕。

你可以用一些for詭計做到這一點：

@setlocal enableextensions enabledelayedexpansion 
@echo off 
echo %0 
for %%f in (%0) do set basename=%%~nf 
echo Will run \arbitrary-path\%basename% 
endlocal 

的%%~nf給你%%f變量的名稱，沒有路徑或擴展。如果你喜歡的東西運行：

C:\Users\Pax\qq.cmd 

，你會看到類似這樣的：

c:\Users\Pax\qq.cmd 
Will run \arbitrary-path\qq 

你可以看到所有的其他有用的擴展，如果你鍵入for /?到命令行窗口：

%~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 

修飾符可以結合得到複合結果：

%~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
