There are several better ways to achieve this.
First you could get find to look for some specific file types:
find . -type f -name '*.[ch]'or use a regex
find . -type f -regex ".*\.\(c\|h\|cpp\|hpp\)"or you can reverse the search and try to exclude binary files
find . -type f ! -regex ".*\.\(png\|zip\)"Also, the GNU version of grep allows you to ignore binary files:
... grep --binary-files=without-matchAnd grep allows recursive searching, so you don't actually need find.
grep --recursive --binary-files=without-match [SEARCH_TERM] .
