Tcl Expect Scripts Auto SSH Logins When automating tasks with shell scripts, you may stumble at points that require user interaction, such as password authentication when checking out an SVN repository. One can handle these events by creating expect scripts. Below is an example script that I put together for SSHing into another computer using a password.
