I am a but a fledgling perl monk, as its my first day. I have a couple questions.

How do I read a csv file?

How do I extract one column of strings in a csv file into an array?

After I can do the above I will use a for loop inside a for loop to compare element 1 of array 1 with all elements of array 2. If any strings are equal I will take the string from array 3 and copy it into the first element of array 4.

Then, How do I print array 4 back into the blank column of my csv file.
