grep and find

Hey, I have a question about using grep and find together to locate all C programs in a directory containing certain words and open the vi editor with each file. I'm not sure how to do this in one command (as in one line). I know find has a "-exec" option that can call vi, but how do you combine this with grep to find only those containing the words "int main ("? Thanks

This should work:

find ~ *.c -exec vi `grep -l "int\ *main\ *("` {} \;

find finds all files *.c and executes vi provided that grep finds the string "int main(". The -l in grep returns the filename.

Merely out of curiosity:

1) Is this 11.19.ii in "Your Unix The Ultimate Guide" by Das?
2) Are you in Sean's class at UCD?
