Unix applescript trouble

I have an applescript that allows me to enter most basic unix commands, but the trouble is, when it outputs the information, I can’t type a response.

For example I type

sudo passwd root

and it puts out

you understand the responsiblility blah blah blah

password:

I want to be able to put in the password and set it by pressing enter.

See? I Need to be able to put something after password and press enter. I can’t use terminal, so I was wondering if there was an AppleScript solution. If anyone could tell me how to make a whole new script for the sole purpose of “sudo passwd root” that would be cool, or modifying the script I already have so I could just type it in afterwards. Thanks
