Note that - as highlighted in previous discussions on the fbsd lists re
the use of xargs with find - find is eminently capable of handling large
argument lists and filenames_with_spaces with its own -exec primary:

        find /tmp/kde-*/ -iname "*wav" -exec rm -vf {} \;

to exec rm for each file individually, or:

        find /tmp/kde-*/ -iname "*wav" -exec rm -vf {} \+

to exec rm for multiple files at once.

Piping to xargs in this case is unnecessary.
