The script stops and says su: incorrect password, these are Linux boxes at when it sends the passwords during the expect/send of su - root.

Is it because I will have to escape the special characters when it starts to send the strings with special characters, I did not have to do this with Solaris boxes?

Is there a way to just alway ignore special characters only during the send part of expect?
