My mate gave me a lot of music the other day. But about half is DRMed and thus unplayable.

I need to know how to remove all of a certain file type from a folder and its sub folders.

I've only been using linux (maemo 5 and ubuntu 9.04/10.04) for a year or so, i thought using (as root):
would work, but it says cannot find file.

Ive managed to find all files with said extension by using(as root):
and it lists all references to all m4p files, but how do i give this output to the 'rm' command.

I've tried(also as root):
to no avail.

Its just my lack of knowledge on how the pipe system works

EDIT:
The directory is /home/user/MyDocs/.sounds/Music
there are sub directories per artist then album e.g.

/home/user/MyDocs/.sounds/Music/Andrew WK/Close Calls With Brick Walls/Track1.m4p


Any help appreciated.

Cheers.
