如何在Windows命令行中仅获取没有路径的文件名？

Question

for /r %f in (*) do echo %f

给出输出文件名以及整个路径

\path\to\dir\<filename>

我如何获得<filename>不包含路径的路径？我需要使用那个“文件名”字符串。

另外，一旦获得文件名，是否可以执行以下操作？

for /r %%f in (*) do (
echo "blah blah blah 'filename'" >> blahblah_filename.txt
)

Answer 1

使用%~nxf了<filename>.<extension>。

是的，你可以这样做：

for /r %%f in (*) do (
echo "blah blah blah '%%~nxf'" >> blahblah_%%~nxf.txt
)

见for /?：

In addition, substitution of FOR variable references has been enhanced.
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

In the above examples %I and PATH can be replaced by other valid
values.  The %~ syntax is terminated by a valid FOR variable name.
Picking upper case variable names like %I makes it more readable and
avoids confusion with the modifiers, which are not case sensitive.
