Start with getting the information you need from the command line.
Space separated tokens from the command line are in the predeclared array @ARGV.
A multi-word pattern needs to have " or ' quotes depending upon OS.

#!/usr/bin/perl

use strict;
use warnings;

my ($pattern, @files) = @ARGV;
print "pattern=$pattern  files are:@files\n";

__END__
example:
>mygrep.pl "some pattern" filea fileb filec
pattern=some pattern  files are:filea fileb filec

I would suggest starting with a more simple subset of the problem.
Write a program that opens FileA.txt and then prints all lines that contain "asdf".
Create FileA.txt with test cases as you wish.
