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
