Have you considered using SSH keys to automate the login? This would be better than trying to work around ssh with expect.

Additionally, your script is vulnerable to people reading it as your password will be visible.

The ssh design is to be secure, so you would be better to exploit that rather than to circumvent it.



Kind regards,
Robin
