scp_auto.sh内容如下：

#! /bin/bash

path1=$1
if [ ! -n "$path1" ]; then
        echo "格式如下：scp_auto.sh /path1"
        exit
fi

#expect自动交互开始
expect -c "
spawn scp $path1 root@192.168.6.56:/opt/browser_api/Public
        expect {
                "*no" {send "yes
"; exp_continue}
                "*password" {send "miao@203
"; exp_continue}
                "*Password*" {send "miao@203
