How to recursively delete all files except certain types?

[acrocephalus]

Hello,
I know this may have been posted many times, but I'm a little bit lost with bash and any help will be much appreciated. I have thousands of files in the /Music directory and its subdirectories. How can I recursively delete everything which isn't and mp3 or flac file? I'd like to get rid of anything which isn't and mp3 or flac file
Thank you so much!

Hi

Use find.

find . -type f  \( -not -iname "*.mp3" -not -iname "*.flac" \) -exec rm {} \;

Test it first though using echo.

find . -type f  \( -not -iname "*.mp3" -not -iname "*.flac" \) -exec echo {} \;

Kind regards

Thanks Matt. I run the code and it worked perfectly.
Cheers,

Hi

No problem. I'm glad it's fixed for you.

I just thought i would mention that find does have a --delete option and a --deletedir option but at the start it always best to check by -exec echo {} the file the filter has found.

That way you can see if your command is correct.

Kind regards
