Hello

I have file A.txt and B.txt

File A A.txt contains the following:

A|B|C|D|E F|G|I|J|K

File B B.txt contains the following:

A|B|C|D|E K|L|N|O|P

My task is to create a script to do the following:

1. Read contents of file A and B, load the content of the first column only into individual array.

ex. @arry={A,F};

2. compare elements of both arrays and print out the differences lines.

I need this for my work! the idea is to pull csv file from database and load it into an archive database then remove archived data from production database. I have spent hours today with no luck working on this

Your help is highly appreciated!

Thank you

newbie monk!
