G'day manan.patel,

Welcome to the monastery.

I can see at a glance that the code you've posted won't compile. This means I don't know what real code you're running. I won't be commenting further on what you have here.

"Hello all, How i can use getopt in my logic??"

There's well-documented, builtin modules to do this. I prefer Getopt::Long. There's also Getopt::Std.
