: > find /usr/local | xargs grep foo
: and why do we need an extra pipe, either?
: 
: 	find /usr/include -name \*f.h -exec grep foo {} /dev/null \;

The extra pipe will fork/exec grep once for each 100k or so characters
of command line args, while this will fork/exec grep for each file.
Guess which one is likely to be faster :-).
