I'm using the following command in my web application to find all files in the current directory that contain the string foo (leaving out svn directories).

find .  -not  -ipath '.*svn*' -exec  grep -H -E -o  "foo"  {} \; > grep_results.txt

How do I find out the files that doesn't contain the word foo?
