I do not know why you are writing a script for this. In redhat for ssh
key fingureprint do:
type ssh-keygen -t rsa or dsa
it will create two .files id_rsa and id_rsa.pub (if you type dsa it
will be id_dsa) in .ssh directory. copy id_rsa.pub key to other box in
.ssh directory and name that authorized_keys.
Remember .ssh should be 700 as permission. Now do ssh from that user
you should be able to login without local password.
