使用expect执行多条命令

#!/bin/bash 
ip=$1  
user=$2 
password=$3 

expect <<EOF  
    set timeout 30
    spawn ssh $user@$ip 
    expect { 
        "yes/no" { send "yes\n";exp_continue } 
        "password" { send "$password\n" }
    } 
    expect "]#" { send "useradd zs\n" } 
    expect "]#" { send "touch /opt/zs.txt\n" } 
    expect "]#" { send "exit\n" } 
    expect eof
