How do I compare a number of hashlists?

[AdityaSaroj]

The -k command allows a single input file. Is there a way to use a list of files for comparison?

Also, is there a way to compare two hashlists directly (instead of a list and the output of the hashdeep command on a directory)?

Say, for example, I have a directory "ABC" on four different machines ideally with the same content. How can I compare the hashlist generated on each machine and get the result in a single file?
