1st line of perl script

[Sunita Rani Pradhan]

Hi All

 

            Perl script  works without the first line ( perl Interpreter
: #! /usr/bin/perl) . What is the real use of this line ? This line does
not through any error on Windows where , this path does not exist .

Why is it so ? 

 

Could anybody explain it  clearly?

 

Thanks
