Ssh to an array of servers in a for loop
There are 4 remote hosts that I have stored in an array. A ssh trust has been created from the local host to each of the remote hosts.
I am trying to ssh to each of the servers in a for loop as shown below.

Code:
declare -a host
 host[${#host[@]}]="server1"
 host[${#host[@]}]="server2"
 host[${#host[@]}]="server3"
 host[${#host[@]}]="server4"

for host in "${host[@]}"
do
  ssh -qtt user@${host} "sh -s "${version}""  <  test.sh
done

test.sh is a file on the local server that I am running on the remote host after I ssh to the remote host. But it is terminating after the first iteration. If I use -n switch it prompts me for password in the second iteration.

Please can you guide me on this issue.

Thanks!

ssh-copy-id

SSH-COPY-ID(1)						    BSD General Commands Manual 					    SSH-COPY-ID(1)

NAME

     ssh-copy-id -- copy public keys to a remote host

SYNOPSIS

     ssh-copy-id [-lv] [-i keyfile] [-o option] [-p port] [user@]hostname

DESCRIPTION

     The ssh-copy-id utility copies public keys to a remote host's ~/.ssh/authorized_keys file (creating the file and directory, if required).

     The following options are available:

     -i file
	     Copy the public key contained in file.  This option can be specified multiple times and can be combined with the -l option.  If a
	     private key is specified and a public key is found then the public key will be used.

     -l      Copy the keys currently held by ssh-agent(1).  This is the default if the -i option was not specified.

     -o ssh-option
	     Pass this option directly to ssh(1).  This option can be specified multiple times.

     -p port
	     Connect to the specified port on the remote host instead of the default.

     -v      Pass -v to ssh(1).

     The remaining arguments are a list of remote hosts to connect to, each one optionally qualified by a user name.

EXIT STATUS

     The ssh-copy-id utility exits 0 on success, and >0 if an error occurs.

EXAMPLES

     To send a specific key to multiple hosts:
	   $ ssh-copy-id -i /path/to/keyfile.pub user@host1 user@host2 user@host3

HISTORY

     The ssh-copy-id utility was written by Eitan Adler <eadler@FreeBSD.org> as a drop-in replacement for an existing utility included with
     OpenSSH.
