Ah, but you could also increase speed vastly by not using a loop:
(with both of them reading from memory)

$ time for i in `find /usr/portage/ -name "*.ebuild" -print`; do egrep -l \
"^KEYWORDS=\".*~ppc.*\"" $i; done

real    1m8.892s
user    0m31.380s
sys     0m41.600s

$ time find /usr/portage/ -name "*.ebuild" |xargs egrep -l "^KEYWORDS=\".*~ppc.*\""

real    0m1.053s
user    0m0.810s
sys     0m0.900s


;) Cheers,
