Windows批处理文件起始目录当“以管理员身份运行” [英] Windows batch file starting directory when 'run as admin'

问题描述

我有一个批处理文件，它是一个目录，因为这个目录中更新文件必须从那里运行良好。

这工作完全正常，当用户运行该批处理文件作为管理员（在Vista需要）功能。然后启动目录为C：\\ Windows \\ System32下

。
有没有什么办法仍然可以知道，从哪个目录下的批处理文件已运行？

我不想让用户手动输入该目录。

I have a batch file which is in a directory and must be run from there as well because it updates files within this directory.
This works perfectly fine, except when the user runs the batch file as administrator (required on Vista). Then the starting directory is C:\Windows\System32.

Is there any way to still be able to know from which directory the batch file was run?
I dont want the user to enter the directory manually.

推荐答案

尝试访问这样的批处理文件路径：

Try to access the batch files path like this:

echo %~dp0

For more information see the following quote from the command for /? that describes how the above command works:

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
