[Linux]获取Linux系统信息

#!/bin/bash

快速获得系统信息的脚本

检查互联网连接

ping -c 1 www.baidu.com &> /dev/null && echo “Internet: Connected” || echo “Internet: Disconnected”

OS类型

os=$(uname -o) # -o, --operating-system print the operating system
echo "Operating System Type : " $os

操作系统发行名称与版本号

这个版本比较粗糙，在CentOS 7写的，没有针对其它发行版本做适配

echo “OS Name : " $(cat /etc/os-release | grep “^NAME=” | cut -f 2 -d”)
echo “OS Version : " $(cat /etc/os-release | grep “^VERSION=” | cut -f 2 -d”)

架构

echo "Architecture : " $(uname -m)

内核

echo "Kernel Release: " $(uname -r)

主机名

echo "Hostname : " $HOSTNAME

内部IP地址

echo "Internal IP : " $(hostname -I)

外部IP地址 使用ipecho.net的IP Echo Service，有时这个网站会打不开 😃

echo "External IP : " $(curl -s ipecho.net/plain; echo)

DNS

echo "Name Server : " $(cat /etc/resolv.conf | grep nameserver | awk ‘{print $2}’)

当前登录的用户

echo "Logged In users: "
who

内存与SWAP

echo "Ram Usages : "
free -h | grep -v “Swap”
echo "Swap Usages : "
free -h | grep -v “Mem”

磁盘空间

echo “Disk Uages :”
df -h | grep ‘FileSystem|^/dev/*’

平均负荷

echo "Load Average : " $(top -n 1 -b | grep “load average:” | awk ‘{print $10 $11 $12}’)

运行时间

echo "System Uptime Days (HH:MM) : " $(uptime | awk ‘{print $3 $4}’ | cut -f1 -d,)
