How do I recursively list all files of type *.mp3 in a Windows .bat file?
提问by clamp
I want to recursively list the absolute path to all files that end with mp3from a given directory which should be given as relative directory.
我想递归列出所有mp3以给定目录结尾的文件的绝对路径，该目录应该作为相对目录给出。
I would then like to strip also the directory from the file and I have read that variables which are in a for-scope must be enclosed in !s. Is that right?
然后，我还想从文件中删除目录，并且我已经阅读了for-scope中的变量必须包含在!s 中。那正确吗？
My current code looks like this:
我当前的代码如下所示：
for /r %%x in (*.mp3) do (
set di=%%x
echo directory !di!
C:\bla.exe %%x !di!
)

Use the command DIR:
使用命令DIR：
dir /s/b *.mp3
The above command will search the current path and all of its children. To get more information on how to use this command, open a command window and type DIR /?.
上面的命令将搜索当前路径及其所有子路径。要获取有关如何使用此命令的更多信息，请打开命令窗口并键入DIR /?。

The batch file below demonstrates how to extract elements of a filename from the variable in a forloop. Save this as file listfiles.bat, and run "listfiles some\folder *.mp3".
下面的批处理文件演示了如何从for循环中的变量中提取文件名的元素。将其另存为 file listfiles.bat，然后运行“listfiles some\folder *.mp3”。
I set up the file finding as a subroutine in the batch file so you can insert it into your own scripts.
我将文件查找设置为批处理文件中的子程序，以便您可以将其插入到您自己的脚本中。
You can also run "for /?" in a cmd shell for more information on the forcommand.
您也可以运行“for /?” 在 cmd shell 中获取有关该for命令的更多信息。
@echo off
setlocal enableextensions enabledelayedexpansion
call :find-files %1 %2
echo PATHS: %PATHS%
echo NAMES: %NAMES%
goto :eof
:find-files
set PATHS=
set NAMES=
for /r "%~1" %%P in ("%~2") do (
set PATHS=!PATHS! "%%~fP"
set NAMES=!NAMES! "%%~nP%%~xP"
)
goto :eof
