运用shell脚本显示主机名字，ipv4地址，操作系统版本，linux内核，cpu型号，内存大小，硬盘大小

[root@localhost ~]# cat systeminfo.sh 
#!/bin/bash
hostname=`hostname -s`
IPv4=`ifconfig eth0 | grep -w 'inet' | awk '{print $2}'`
OS=`cat /etc/redhat-release`
linux=`uname -r`
cpu=`lscpu | grep '型号名称' | awk '{print $2,$3,$4,$5,$6,$7.$8}'`
mem=`free -h |free -h | grep Mem | awk '{print $2}'`
disksize=`lsblk | grep '^sd'|awk '{print $1,$4}'|paste -s -d,`
echo -e "Hostname is :          ${hostname}"
echo -e "IPV4 adress is :       ${IPv4}"
echo -e "OS's version :         ${OS}"
echo -e "Kernel version is :    ${linux}"
echo -e "CPU version is :       $cpu"
echo -e "Memory's size is :     ${mem}"
echo -e "Disk size is :         ${disksize}"

运行结果
