# interactive time
set timeout 2
set response 0

# set variables
set port [lindex $argv 0]
set user [lindex $argv 1]
set host [lindex $argv 2]

# interactive windows
spawn  ssh -p$port  $user@$host

# 此处 有时候会提示，需要跳过这类的提示。
#expect "Are you sure you want to continue connecting (yes/no)?"
#send "yes\n"

expect "password:*"
send "Your password\n"

expect "]$"
send "su - root -c 'passwd $user'\n"

expect "Password: "
send "root's password\n"

expect "New UNIX password: "
send "new password\n"
expect "Retype new UNIX password: "
send "new password\n"

expect eof

我来帮你修改一下，针对有些host没有信任需要yes/no确认的时候，可以如下
expect {
        "yes/no"   { send "yes\n" ;exp_continue}
        "password:" { send "your password\n" }
}
