expect结合ssh遍历线上机器

有个需求，有个文件删除了，但是不确定线上机器还都存不存在


#!/home/work/.jumbo/bin/expect -f
set timeout -1
set mac [lindex $argv 0]
set password "***"
spawn ssh username@$mac
expect {
        "(yes/no)?" {
                        send "yes\r"
                        expect "*password:" { send "$password\r"}
                }
        "*password:" { send "$password\r"}
}
expect {
        "*password:" {
                send "\003"
                send_user "this mac nologin"
        }
        ".*" {
                send "cd /home/work/odp/data/app/searchbox/baiduboxapp/config/android/; ls\r"
        }
}
expect ".*"

#!/bin/bash
get_instance_by_service *** | while read mac
do
        echo $mac
        res=`./expect.sh $mac`
        if echo $res | grep -q 'this mac nologin'; then
                echo -e "\e[1;31m======nologin\e[0m"
        elif echo $res | grep -q 'opact'; then
                echo -e "\e[1;33m======has\e[0m"
        else
                echo -e "\e[1;32m======no\e[0m"
        fi
done
