I wish to compare the lines from file1.txt with file2.txt and export what are the missing lines not found in file2.txt to another result.txt

The CPAN module Algorithm::Diff is also built for doing this sort of thing.

If you're on a system that supports it, the easiest way might be to use the Unix diff command.

For a pure Perl solution, you might be able to do something with the Array::Compare module from CPAN.
