Re: comparing 2 files and creating third file with uncommon content

If this is not just for the sake of learning to use Perl, this type of task can be done with well known command line tools e.g.

diff -n file1 file2 | egrep -v '^[ad]' > file3
[download]

will find the differences and write them to file3.

You may need to install cygwin or native versions of these tools.
