Need Bash script help
I have a bash script that does a few things for me. I am setting up a method of using passwordless ssh to move files between a server and several systems. My issue is that I want to use a bash script to automate the keygen and the initial setup. Here is my script
Code:
#!/bin/bash
#!/usr/bin/expect -f

#=====setup ssh to the backup server====

echo "Follow along with the enter key for the next few questions."
echo "We are setting up the SSH connections to the cloud server."
ssh-keygen
spawn ssh-copy-id  user@10.10.10.10
expect "password:"
sleep 1
send -- "password\r"
sleep 3
send -- "exit\r"
spawn ssh user@10.10.10.10
sleep 10
send -- "exit\r"
expect eof

When I run this script I get no interaction and back to a bash prompt. Running th ecommands individually the ssh key is copied and I can ssh into the server with no issues. What am I missing?

Thanks

ssh-keysign

SSH-KEYSIGN(8)						    BSD System Manager's Manual 					    SSH-KEYSIGN(8)

NAME

     ssh-keysign -- ssh helper program for host-based authentication

SYNOPSIS

     ssh-keysign

DESCRIPTION

     ssh-keysign is used by ssh(1) to access the local host keys and generate the digital signature required during host-based authentication with
     SSH protocol version 2.

     ssh-keysign is disabled by default and can only be enabled in the global client configuration file /etc/ssh/ssh_config by setting
     EnableSSHKeysign to ``yes''.

     ssh-keysign is not intended to be invoked by the user, but from ssh(1).  See ssh(1) and sshd(8) for more information about host-based authen-
     tication.

FILES

     /etc/ssh/ssh_config
	     Controls whether ssh-keysign is enabled.

     /etc/ssh/ssh_host_dsa_key
     /etc/ssh/ssh_host_ecdsa_key
     /etc/ssh/ssh_host_rsa_key
	     These files contain the private parts of the host keys used to generate the digital signature.  They should be owned by root, read-
	     able only by root, and not accessible to others.  Since they are readable only by root, ssh-keysign must be set-uid root if host-
	     based authentication is used.  Note that ssh-keysign is not set-uid by default on Mac OS X.

     /etc/ssh/ssh_host_dsa_key-cert.pub
     /etc/ssh/ssh_host_ecdsa_key-cert.pub
     /etc/ssh/ssh_host_rsa_key-cert.pub
	     If these files exist they are assumed to contain public certificate information corresponding with the private keys above.

SEE ALSO

     ssh(1), ssh-keygen(1), ssh_config(5), sshd(8)

HISTORY

     ssh-keysign first appeared in OpenBSD 3.2.
