Anything will match the empty string; regular expressions look for a match anywhere, and finding "nothing" anywhere trivially matches. You need to anchor it to make it more picky about what to find. $7 ~ /^$/ checks for an empty string (beginning of string adjacent to end of string) but it's probably more efficient to simply use equivalence comparison against the empty string.
guys forget the find command coz with find command u can't get condational output like grep. I will give small example :-
