Using AWK to determine how many lines contain a string

I'm trying to use AWK to determine how many lines in a file contain a string.

BEGIN {RS=FS} 
{if ($0 ~ /ed/) n++}
END {print n}

Works fine as long as ed is preceded by white space no matter what follows it, such as ed or education, but if the line contains muted or fed, it doesn't register them. I thought /.*ed/ would correct this but no such luck.

Or just use grep with the -c option to count occurrences:

grep -c ed file
4

Just remove BEGIN {RS=FS} and you should be fine.

cat file

ed
education
not here
covered
fed
not here


awk '/ed/ {n++} END {print n}' file
4

$0~/ed/ is the same /ed/. It will search the line and if any ed is found increment the counter.
So in my example, 4 ed are found.
