它们是增强的可变取代。它们修改批处理文件中使用的%N个变量。如果你在Windows中进行批量编程,那将非常有用。%~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%~$PATH:I - searches the directories listed in the PATH environment variable and expands %I to the fully qualified name of the first one found. If the environment variable name is not defined or the file is not found by the search, then this modifier expands to the empty string您可以通过运行找到上述内容FOR /?。
是的,您可以使用下面给出的其他快捷方式。在你的命令中,~d0意味着第0个参数的驱动器号。~ expands the given variabled gets the drive letter only0 is the argument you are referencing由于第0个参数是脚本路径,因此它会为您获取路径的驱动器号。您也可以使用以下快捷方式。%~1 - expands %1 removing any surrounding quotes (")%~f1 - expands %1 to a fully qualified path name%~d1 - expands %1 to a drive letter only%~p1 - expands %1 to a path only%~n1 - expands %1 to a file name only%~x1 - expands %1 to a file extension only%~s1 - expanded path contains short names only%~a1 - expands %1 to file attributes%~t1 - expands %1 to date/time of file%~z1 - expands %1 to size of file%~$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当你运行CALL /?时,也可以直接在命令提示符中找到它。或FOR /?
