A simple one # echo "jerry jerry" | tr " " "\n" | grep -c jerry 2

But what about jerry.jerry or jerry/jerry or jerry,jerry or....

Well he never stated a non-standard field separator, but if that is the case, with awk:

The question wasn't suficiently well defined. After all, is "jerryjerry" a count of "1" or "2" ? :-) :-)

To make the "tr" case more general: echo "jerry jerry" | tr -c '[:alnum:]' '\012' | grep -c jerry

Or we could be silly (if each occurance is meant to be counted): echo "jerry jerryjerryjerryhellojerry" | sed 's/jerry/\ jerry/g' | grep -c jerry
