    For split i understood that the data is splitted based on "|" .For eg : abc |efg abc and efg are obtained.but didnt understood y $-,2 and grep are used along with that.Plz explain
      um, see split, first argument is regular expression, the other arguments are string to split, and the limit

      the grep is used to skip empty lines
