查看Linux系统信息脚本（运维）

前言

这是一个查看Linux系统硬件信息的shell脚本。

脚本内容

#!/bin/bash
#description:system_info
echo -e "-------------------------------System Information----------------------------"
echo -e "Hostname:\t\t"`hostname`
echo -e "uptime:\t\t\t"`uptime | awk '{print $3,$4}' | sed 's/,//'`
echo -e "Manufacturer:\t\t"`cat /sys/class/dmi/id/chassis_vendor`
echo -e "Product Name:\t\t"`cat /sys/class/dmi/id/product_name`
echo -e "Product Version:\t"`cat /sys/class/dmi/id/product_version`
echo -e "Serial Number:\t\t"`cat /sys/class/dmi/id/product_serial`
lscpu | grep VMware &>/dev/null
echo -e "Machine Type:\t\t"`if [ $? -eq 0 ]; then echo "VMware"; else echo "Physical"; fi`
echo -e "Operating System:\t"`hostnamectl | grep "Operating System" | cut -d ' ' -f5-`
echo -e "Version:\t\t"`cat /etc/redhat-release `

echo -e "Active User:\t\t"`w | cut -d ' ' -f1 | grep -v USER | xargs -n1`
echo -e "System Main IP:\t\t"`hostname -I`
echo ""
echo -e "-------------------------------CPU/Memory Usage------------------------------"

echo ""
echo -e "-------------------------------Disk Usage>50%-------------------------------"
df -Ph | sed s/%//g | awk '{ if($5 > 50) print $0;}'
