Answer 1

You can get it like this:

wget -q -O - "http://www.google.com/finance/converter?a=1&from=USD&to=PLN"|awk -F"[ >]" '/<div id=currency_converter_result>/ {printf "%s %.2f\n",$4,$8}'
USD 3.03

To get it into an variable:

val=$(wget -q -O - "http://www.google.com/finance/converter?a=1&from=USD&to=PLN"|awk -F"[ >]" '/<div id=currency_converter_result>/ {printf "%s %.2f\n",$4,$8}')
echo "$val"
USD 3.03
