需求：在实施和运维工作中有时候会因为一些特殊原因需要整理服务器台账信息，很多时候没有厂商提供的信息，只能自行整理，但一台台查看太浪费时间，所以整理一个脚本以便不时之需
脚本原理，
1、设置数组变量，并指定服务器ip列表
#需要检查的服务器列表 IP@@ssh端口@@用户名@@密码
serverInfo=(
192.168.195.129@@22@@root@@dragon
192.168.195.130@@22@@root@@dragon
)2、利用expect自动交付远程到服务器执行命令生成临时文件
3、取回临时文件，解析各项参数
脚本执行结果

?shell脚本
理论上适用于linux x86，脚本运行需要安装expect(依赖tcl)，请自行安装，或者下载完整脚本包
