yum clean all

Another method to get the sensex. This method is more realiable in working - but the data might be a bit old. Data supplied by Yahoo Finances.

curl -s 'http://download.finance.yahoo.com/d/quotes.csv?s=%5EBSESN&f=sl1d1t1c1ohgv&e=.csv'| awk -F ',' '{print $2}'

This one command will fetch and display the latest sensex figure in Linux. This command basically downloads a page, locates a specific line, and then extract just the necessary portion from it. I am sure you could find other uses for this method.

curl -s "http://money.rediff.com/money/jsp/markets_home.jsp" |grep ''|head -n1|perl -pe 's/^.+\">([\d\,\.]+)<\/TD>.+$/\1/i;'
