Hello friends, I am new to perl programming and I would like some help about reading files.

I wish to know how can you can do something like

 open my $input, '<', $ARGV[0];
       open my $output,'>', $ARGV[1];

        while (my $sentence = <$input>) {
    
            my $substring = 'clothes.*?mall';
            $sentence =~ read-only{$substring}; 
        print $output , $sentence;             
 
    }

and read from a text file that contains something like :"I used to buy clothes from the mall because they are cheap" only the values between the words "clothes" and "mall" so I could do certain operations with them and after I do all the operations with the values between the 2 keywords I want to output the file with all the values("I used to buy clothes' from the 'mall because they are cheap") the words between ' ' represent the words " from the " after the operations were done on them.

P.S. Sorry if it is a stupid question or a stupid example but I am super new in all this and a terrible question asker.
