I would think perl or expect should help with this situation. Expect is a
wrapper program that can make interactive programs non-interactive. Or if
adduser accepts input similar to adduser on linux (e.g. adduser options
username) then have a shell script read in the desired username and then echo it
into the command
#!/bin/bash
$USER=$1
`adduser $USER`
