Hi all,

I am trying to concatenate all the files in a directory.

The file format is the following:

file 1:

>A

Amber, Amy

>B

Barbie, Bambie

file 2:

>A

Austin, Aurora

>C

Cathy, Candy

file 3:

>B

Bob, Barbara

>C

Cane, Carter

I want to concatenate the files so that the final file reads:

>A

Amber, Amy, Austin, Aurora, -, -

>B

Barbie, Bambie, -, -, Bob, Barbara

>C

-, -, Cathy, Candy, Cane, Carter.

I tried to use hash tables but I am finding it very hard. Is there an easy way to do this?

Thanks!
