[clug] Help with bash script

With regard to spaces in file names and find | xargs, I have found the following
to work:

  find . -type f -print | sed -e 's/ /\\ /g' | xargs whatever

Without this, xargs will indeed see multiple arguments from a single file name
containing spaces. It is very much more efficient to use xargs than to use
find's -exec.

Cheers ... Duncan.
