Yes, expect will work, but if you can use ssh, use it, it will be easier. Setup ssh to use RSA key for authentication, so it won't prompt for a password. Then just execute "ssh username(a)remote.server somecommand" and it will run "somecommand" and the output will be sent back to you. -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".
