You were almost there. First, add the filename:

Code:
find $dir -type f -exec grep $string {} \; -print

Then - you got that explained already - use "grep -n" to get the line numbers:

Code:
find $dir -type f -exec grep -n $string {} \; -print

I suggest reading a man page now and then if you encounter a program or a program call you don't understand fully, like the "-n" switch in "grep". You could have looked up "-n" on the man page of grep and find out this way what its purpose is. This is generally a fruititious approach.

I hope this helps.
