在本教程中，脚本将获取有关Linux服务器的信息，例如登录的用户，正常运行时间，平均负载，可用内存，磁盘使用率。
该脚本有助于在一秒钟内查看有关服务器的所有信息。

如果需要从多个服务器中查找系统信息，管理员可以修改脚本位。

脚本运行命令w，uname，uptime，free和df。
从正常运行时间命令脚本中获取平均负载。

使用Shell脚本获取服务器信息

让我们检查shell脚本以查找服务器信息。

#!/bin/bash
#clear console
clear
#just echo welcome messages
echo "This is information provided by 
This is information provided by ./system_info.sh . Program starts now.
