Alternatively, one could use grep's -H option ;^)

/dev/null is the second file

See, that has two consequences. grep is spawned once for every find
match (which, if you're running it on something slow and old is an
issue). Also, since grep is only spawned with one filename, it will not
(iirc) issue the names of matching files in addition to the matching
line itself. Of course, if that's a desired feature, you're sorted, but
in the original spec, I suspect it wasn't...

I'd go for:
find . -type f -exec grep 'foo' {} /dev/null \;
or possibly:
find . -type f -exec grep -q 'foo' {} \; -print

It's also going to break grep if find returns too many results. And find there will return directories too, which grep will not take too kindly to. My SOP recursive grep is: find . -type f -print0 |xargs -0 grep 'foo' OTOH, I've no idea offhand why I don't just use rgrep (aka `grep -r`)... :-) -- Right now, there are scr1pt k1dd13s plotting to DDoS my network, my co-lo server is not responding to pings and the people that I IRC with may be involved in both.
