Nick,
thanks for the compliment.
find . -type f | xargs -0 grep whatever
manpage for xargs,
--null, -0
Input filenames are terminated by a null character instead of by
whitespace, and the quotes and backslash are not special (every character
is taken literally). Disables the end of file string, which is treated
like any other argument. Useful when arguments might contain white space,
quote marks, or backslashes. The GNU find -print0 option produces input
suitable for this mode.

Ahh.
find . -type f -print0 | args grep
will also work.
Nope, does not.
That produces one big string...
=========================================
Lastly,
find . -name \* -maxdepth 0 | xargs -0 ls -l | cut -b 57- | grep \ | wc -l
reports 68, the number of files in my current directory with spaces in
their name.
Derek.
