Yes each line matching "cert_codes" will be stored in aa.txt.
But multi lines will not be grepped .Check example given below, here even though it's a multi line where 'robert' appears only robert was grepped and 'bob' missed out.
Is this what you were looking for ?
$> cat test.sh
ary=("robert" \
" bob")
for a in ${ary[@]}
do
echo $a
done
$> grep robert test.sh
ary=("robert" \
