'getting Missing opening '(' after keyword error in ffmpeg loop command

How can I run this command that runs in Linux in Windows 10 powershell for ffmpeg?

for file in D:\input\*.mkv; do ffmpeg -i "$file" -map 0:v:0 -map 0:a:0 -map 0:a:1 -map 0:s:0 -map 0:s:1 -c:v copy -c:a flac -c:s copy D:\output; done

I tried

for file in D:\input\*.mkv; do ./ffmpeg -i "$file" -map 0:v:0 -map 0:a:0 -map 0:a:1 -map 0:s:0 -map 0:s:1 -c:v copy -c:a flac -c:s copy D:\output; done

But I get this error:

At line:1 char:4
+ for file in D:\input\*.mkv; do ./ffmpeg -i "$fil ...
+    ~
Missing opening '(' after keyword 'for'.
At line:1 char:52
+ for file in D:\input\*.mkv; do ./ffmpeg -i "$fil ...
+                                                    ~
Missing statement body in do loop.
    + CategoryInfo          : ParserError: (:) [], ParentContainsErrorRecordException
    + FullyQualifiedErrorId : MissingOpenParenthesisAfterKeyword

So how can I change this command to run properly in Windows 10 powershell?

Solution 1:[1]

As the error indicates, PowerShell does not recognize bash's for loop syntax.

In PowerShell, you'd do something like this instead:

Get-ChildItem -Path D:\input -Filter *.mkv |ForEach-Object {
  ./ffmpeg -i $_.FullName -map 0:v:0 -map 0:a:0 -map 0:a:1 -map 0:s:0 -map 0:s:1 -c:v copy -c:a flac -c:s copy D:\output
}

Solution 2:[2]

use rather 'Developer Command Prompt for vs 2022' than powershell(in windows Terminal).
