As we know there are 3 ways a system shell command to be executed.

What is difference between these three?
You should not have asked that question here; you should have looked up the answer in the docs.

Sheesh!

This is the first thing I read on perl.beginners after time away.

Are you really from the Cocos Islands, Gunnar?

I think you should talk to the other abusive people who like to post here and
form a separate group.

I take it that you don't agree.

The OP wondered about two built-in functions and the backticks operator. I can't think of a more natural first step to find out how they work than reading about them in the Perl documentation. Do you mean that I'm abusive by suggesting that people make it a habit to use the docs at first hand? If that's what you mean, I think you are plain stupid.
