Can you please help me determine where there are unmatched quotes (")
in my .mailfilterrc file?

grep -c returns the number of lines where the " appears, but I need
something that counts the number of instances of " per line.

Something like

while read LINE; do
count how many times " occurs in this line
if count=0 then ignore # Skip zero and
if count<>2 then echo $LINE # two; show all others
done <.mailfilterrc

TIA, I'm crosseyed looking at 377 lines :<
