Question

过去4-5小时我花了一些时间来修复我的脚本并尝试了几件事，但它仍然无法正常工作。这是工作部分：

    @echo off
    rem automatically sort MP3s into an existing structure or add folders if needed
    rem example of MP3-file pattern: Wu-Tang Clan - Gravel Pit (LP Version Clean).mp3

    SETLOCAL

    rem set variables
    SET "source=g:\music\folder"
    SET "str=Wu-Tang Clan - Gravel Pit (LP Version Clean).mp3"
    SET "test=%source%\%str%"

    rem split the filename from the remaining path. Take the left part
    rem and assign it to %band% while the right part gets assigned to %song%
    FOR /f "delims=" %%i IN ("%test%") DO SET "result=%%~nxi"

    SET "band=%result: - =" & SET "song=%"

    rem If there is no such folder (%band%), create it
    IF not exist "%source%\%band%" MD "%source%\%band%"

    rem As soon as there definetely is a fitting folder
    rem move the file over there.
    MOVE /-Y "%source%\%result%" "%source%\%band%"

下一步是通过for循环增强代码，这样我就不必编辑每个3k +文件的脚本了;）

我努力让这段代码得以实现，但失败了： @echo关闭 SETLOCAL

    SET "source=g:\music\folder"

    FOR %%f IN (%source%\*.mp3) DO (
    echo %%f

    FOR /f "delims=" %%i IN ("%%f") DO SET "result=%%~nxi"

    SET "band=!result: - =" & SET "song=%"

    IF not exist "%source%\%band%" MD "%source%\%band%"

    MOVE /-Y "%source%\%result%" "%source%\%band%"
    )
    pause

所以我添加了一个for循环，并且%% f首先被正确填充，并且不在下一个for循环中。

    FOR %%f IN (%source%\*.mp3) DO (
    echo %%f

导致：“g：\ music \ folder \ Wu-Tang Clan - Gravel Pit（LP版本清洁）.mp3”

就像它应该的那样。但在那之后

    FOR /f "delims=" %%i IN ("%%f") DO SET "result=%%~nxi"

结果，并且每个后续变量都是空的。

我尝试用第二个变量作为'帮助'来修复它：

    FOR %%f IN (%source%\*.mp3) DO (
    SET "helper=%%f"
    FOR /f "delims=" %%i IN ("%helper%") DO SET "result=%%~nxi"

在我读完之后，甚至添加了'enabledelayedexpansion'，然后去了

    FOR /f "delims=" %%i IN ("!helper!") DO SET "result=%%~nxi"

仍然无效。

现在我真的需要一些帮助，我真的很感激它：）

下一个代码段可以正常工作。请注意，SET "band=%result: - =" & SET "song=%"技巧无法使用!延迟扩展执行，而不像% - 扩展。因此，该命令被移动到:myset子例程并通过call command执行。

@echo off
SETLOCAL EnableExtensions EnableDelayedExpansion
SET "source=g:\music\folder"
FOR %%f IN (%source%\*.mp3) DO (
  echo %%f
  FOR /f "delims=" %%i IN ("%%f") DO SET "result=%%~nxi"
  call :myset
  IF not exist "%source%\!band!" MD "%source%\!band!"
  MOVE /-Y "%source%\!result!" "%source%\!band!"
)
goto :skipMyset

:myset
  SET "band=%result: - =" & SET "song=%"
goto :eof

:skipMyset
pause
