trouble with deleting files on unix

Hi there, I know this is not a unix board, but maybe someone had to cope with the same problem. I have a couple of wired filenames matching all this pattern .jpeg: How can I delete all files matching this pattern recursive in all directories? I tryed : rm -r test *.jpeg:* But this only deletes the files in the test dir not in the test/subdir Thanx for any help Andy
