问题描述
这是代码:
for /r %%a in (*.jpg, *.png, *.bmp, *.exe) do (
for /d %%d in (%CD%) do (
set newname=%%~nd%~x1
ren "%%~a" "!newname!%%~Xa"
echo media file in %%~fa renamed to "!newname!%%~Xa"
)
)
主要问题是子文件夹中的文件最终以filename为父目录名，而我是从中运行bat文件的.
The main problem is that the files in the subfolders end up with filename as the parent directory name i run the bat file from.
发生的事的示例:
C:\parent\name.jpg renamed to C:\parent\parent.jpg
C:\parent\child\name.jpg renamed to C:\parent\child\parent.jpg
C:\parent\child1\child2\name.jpg renamed to C:\parent\child1\child2\parent.jpg
我需要:
C:\parent\1.jpg rename to C:\parent\parent.jpg
C:\parent\child\1.jpg rename to C:\parent\child\child.jpg
C:\parent\child1\child2\name.jpg renamed to C:\parent\child1\child2\child2.jpg
有帮助吗?
推荐答案
这将把ren命令回显到屏幕上.
删除echo关键字以使其实际上执行重命名.
This will echo the ren commands to the screen.
Remove the echo keyword to make it actually perform the renames.
@echo off
for /r %%a in (*.jpg *.png *.bmp *.exe) do for %%b in ("%%~dpa\.") do echo ren "%%~a" "%%~nxb%%~xa"
pause
第一个%% a FOR命令以递归方式返回每个文件规范，每个文件的格式为:c:\path\to\folder\filename.ext
The first %%a FOR command returns each filespec recursively and the format of each file is:c:\path\to\folder\filename.ext
第二个%% b FOR被赋予c:\path\to\folder部分，并在其末尾添加\.使其成为c:\path\to\folder\.，从而解析为当前目录to并使其将folder解释为文件名.
The second %%b FOR is given the c:\path\to\folder portion and \. is added to the end making it c:\path\to\folder\. which resolves to the current directory of to and making it interpret folder as the filename.
因此，%%~nxb返回文件名和%% b的扩展名，在本例中为folder，该文件名和扩展名在重命名命令中使用. %%~xa返回%% a字符串的.extension.
So the %%~nxb returns the filename and extension of %%b which is folder in this case, and that is used in the rename command. %%~xa returns the .extension of the %%a string.
我希望这很清楚，同时还要检查代码.
I hope that's fairly clear, along with examining the code.
