Ssh – How to use expect in Bash script and ssh-copy-id

bashexpectssh

From a bash script:

source ./expect.sh

I am including a expect code:

#!/bin/bash
/usr/bin/expect <<EOL
spawn ssh-copy-id -i /home/user/.ssh/id_rsa.pub 111.111.111
expect '*?assword*'
send 'thepassword'
interact
EOL

And I am getting this:

spawn ssh-copy-id -i /home/user/.ssh/id_rsa.pub 111.111.111.111
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
root@111.111.111.111's password:

Then I try to connect and I am prompted for a password…

Checking the server, I'm certain no key was uploaded because I would expect to list the "authorized_keys" file:

root@server: ls /home/user/.ssh/
known_hosts

What am I doing wrong?

The problem is that the ssh client is reading directly from the terminal for the password, not from stdin.

The easiest way I know around this is to install 'sshpass', then use this (without Expect):

sshpass -p "thepassword" ssh-copy-id -i /home/user/.ssh/id_rsa.pub user@111.111.111.111
