As we know there are 3 ways a system shell command to be executed.
1.> $var = system("command");

What is difference between these three?
You should not have asked that question here; you should have looked up
the answer in the docs. I think the best starting point is
perldoc -f system
Another thing would have been if you had made an attempt with the docs,
and needed help to understand it. _That_ would have been a good reason
to ask for help.
