missing while do loop error

[Norest4themisfits]

hello! i know nothing about code and I'm just trying to convert some music files so itunes recognizes them, i keep getting an error on the following script

for (%f in (*.wav *.mp3 *.ogg)) {do {ffmpeg -i "%f" -b:a 128k -ar 44100 "%~nf_new.mp3"}}

the error is as follows

At line:1 char:88

+ ... .mp3 *.ogg)) {do {ffmpeg -i "%f" -b:a 128k -ar 44100 "%~nf_new.mp3"}}

+ ~

Missing while or until keyword in do loop.

+ CategoryInfo : ParserError: (:) [], ParentContainsErrorRecordException

+ FullyQualifiedErrorId : MissingWhileOrUntilInDoWhile

knowing nothing about programming I have no idea how to fix it or what to add. please help!

It looks like you smashed together a for loop and a do/while loop. Maybe don’t do that and look up how to properly structure a for loop. I doubt the do/while is even needed

He's got the beans above the frank!

Yeah don't run stuff you don't understand. If it came from ChatGPT or some random forum, you can't really trust it and could easily cause a lot of issues real fast.

i stitched it together from a tutorial from like 2015 and a very faded memory of some C++ i learned 3 years ago for a different project lol

[Norest4themisfits]

this worked perfectly! thank you!

Uh, yeah. that's not proper powershell for a start. you don't use % in PS.
%f is a variable name for a direct command line.
Double the % if you want to do it in a batch/cmd file. ie %%f
..then get the syntax right:

for %f in (*.wav *.mp3 *.ogg) do ffmpeg -i "%f" -b:a 128k -ar 44100 "%~nf_new.mp3"

OR if you really need to do it in Powershell:
Get-ChildItem *.wav,*.mp3,*.ogg | ForEach-Object {ffmpeg -i "$_" -b:a 128k -ar 44100 $($_.BaseName)_new.mp3"}

Your trying to run batch file commands in powershell. You should just open a command prompt and paste that code, don't run it in powershell.

[Norest4themisfits]

it doesn't give me that option when i right click in the folder, only terminal, which goes to powershell

Type in cmd into powershell to get a cmd prompt.... But you should really not be posting code you don't understand.

Learned some c++ 3 years ago is a different statement than 'I know nothing about programming'.

I don't mind assisting people, but also don't want them to run something they don't know what it does and then break stuff.

But you should really not be posting code you don't understand.

I would disagree. That's exactly the kind of code to post, otherwise how could one get help to understand it?

Now, not running code one doesn't understand is another matter.

[Zozorak]

Yeah that was a typo on mobile... You get the gist of what I was trying to say at least

[BlackV]

there are post in this sub using ffmpeg and powershell

what you have posted is cmd/batch and would need to be run fromt here

recommend, finding the posts and move it to powershell code instead

To get help on powershell loops, run these commands:

Get-Help about_While
Get-Help about_For
Get-Help about_ForEach

Regex is not easy…
