Hi All,

How to find out whether the string contains null values or empty data.

=20

For example : I have one scalar variable $str and now I want to check
whether it contains any data or not.

=20

What I did  : If ($str eq "NULL" || $str eq " "){ print $str conatins
nothing\n";}

Is this correct?? Because doing as per above code , I am not getting
proper result.

Please help
