I'm pretty sure David's code above will do exactly what the OP asked for.

This is about searching through a list of files, so I think the  
subsequent discussion of stdin might have been a bit confusing, since  
it's only one file.

The -L and -l options are about what grep outputs: the name of a file,  
not the matching string itself.

Man grep's "The scanning will stop on the first match" refers to  
scanning inside a certain file; so once a decision has been reached as  
to whether it satifies the condition or not, then grep will move on to  
testing the next file.
