我正在查看定義以下變量的批處理文件：set _SCRIPT_DRIVE=%~d0set _SCRIPT_PATH=%~p0什么%~d0或%~p0實際意味著什么？對于諸如當前目錄，驅動器，腳本參數之類的東西，是否有一組眾所周知的值？我可以使用其他類似的快捷方式嗎？

神奇變量%n包含用于調用文件的參數：%0是bat文件本身的路徑，%1是后面的第一個參數，%2是第二個參數，依此類推。
由于參數通常是文件路徑，因此有一些額外的語法來提取路徑的一部分。~d是驅動器，~p是路徑（沒有驅動器），~n是文件名。它們可以組合在一起，因此~dp驅動器+路徑。
%~dp0 因此在bat中非常有用：它是執行bat文件所在的文件夾。
您還可以獲得有關該文件的其他類型的元信息：~t是時間戳，~z是大小。
看看這里為所有命令行命令的參考。代字號幻代碼下所描述的。

它們是增強的可變取代。它們修改批處理文件中使用的％N個變量。如果你在Windows中進行批量編程，那將非常有用。
%~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
您可以通過運行找到上述內容FOR /?。

是的，您可以使用下面給出的其他快捷方式。在你的命令中，~d0意味著第0個參數的驅動器號。
~ expands the given variable
d gets the drive letter only
0 is the argument you are referencing
由于第0個參數是腳本路徑，因此它會為您獲取路徑的驅動器號。您也可以使用以下快捷方式。
%~1 - expands %1 removing any surrounding quotes (")
%~f1 - expands %1 to a fully qualified path name
%~d1 - expands %1 to a drive letter only
%~p1 - expands %1 to a path only
%~n1 - expands %1 to a file name only
%~x1 - expands %1 to a file extension only
%~s1 - expanded path contains short names only
%~a1 - expands %1 to file attributes
%~t1 - expands %1 to date/time of file
%~z1 - expands %1 to size of file
%~$PATH:1 - searches the directories listed in the PATH
environment variable and expands %1 to the fully
qualified name of the first one found. If the
environment variable name is not defined or the
file is not found by the search, then this
modifier expands to the empty string
%~dp1 - expands %1 to a drive letter and path only
%~nx1 - expands %1 to a file name and extension only
%~dp$PATH:1 - searches the directories listed in the PATH
environment variable for %1 and expands to the
drive letter and path of the first one found.
%~ftza1 - expands %1 to a DIR like output line
當你運行CALL /？時，也可以直接在命令提示符中找到它?；騀OR /？
