Helo fellow monks!
I have started using Perl a couple of weeks ago, and I am now faced with my first serious problem.
I have 2 files let's say with words,namely 
FILE1
one
two
three
four
five
six
seven
#############
FILE2
<nine>
two
eleven
twenty
one
thirty
forty

Waht I want is to create 3 files, the FIRST will store only the words that appear in FILE1,
the SECOND will store only the words that appear in FILE2 and the third will store the common words.
I know how to open files and create arrays or hashes with the words they contain, and I have created 2 hashes one for each file.
What I don't know is how can I compare the 2 hashes and find the common and not common words so that I print them in the respective output files.
Thank you in advance!
