Disclaimer noted.

Everyone seems to think that some sort of echo statement is needed for the
filenames.  Use

grep $string $file /dev/null

This way, the file containing the matching string is printed before the
match.

A portable way of doing this, though VERY inefficient is:
find . -type f -exec grep $string '{}' /dev/null \;

Shell solutions are trivial and left as an exercise to the imagination.
