    So after being told that system is not the right way to do this you still insist that it's what you want to use. And "specifically", too. Fine, here you go:

    #!/usr/bin/perl
use strict;
use warnings;
my $r=`perl -e 'system("ls")'`;

    That uses system and will make your tutor give you 0 points for the exercise along the way.


    All dogma is stupid.

    is there any way to achieve this using system function, please answer specifically!

      Well, I believe this is not entirely true. You might capture the stuff if you fiddled with STDOUT and STDERR enough, but it would not be nice. And it's totally unnecessary. So I think the precise answer is "You could, but it would not be pretty so you should not. Use the tools that were designed to do that!"

        But that wouldn't, specifically, be using the system function. It would be using "the system function plus a lot of other stuff". Otherwise known as backticks or qx//, which had already been specifically rejected.
