recursion - Using IF whiting a FOR in Batch

Question

I need a script that checks the name of a CDG file and if is not present in the same folder another file with the same name in .mp3, then deletes the cdg file.

I thought to implement it with this simple code:

@echo off
for /R %1 %%f in (*.cdg) do (
   if exist %%~nf.mp3 (
      del %%f
     )
)

But it return me with a syntax error in IF construct.

I tried to google it but it seems no-one had same problem (or i'm really bad in using google)

Can please someone tell me where i'm wrong?

Answer 1

Ok, heres an easy way of doing this with forfiles if your using Windows 7:

forfiles /m "*.cfg" /c "cmd /c if exist @fname.mp3 del @path"

That alone should work fine, and it's short enough to be typed directly in cmd.

这可能是由于文件名包含空格。如果是这样，那么：

@echo off
for /R %1 %%f in (*.cdg) do (
if exist "%%~nf.mp3" (
   del %%f
   )
)

注意：引号

此外，您应该研究一下forfiles（因为您只需要一行代码），但这只有在您使用 Windows 7 时才有效。

试一试：

@echo off
for /R "%~1" %%f in (*.cdg) do (
   if exist "%%~dpnf.mp3" (
      del "%%f"
     )
)
