命令比较多，统一整合了一下：
1、新建文件touch getComputerConf.sh
2、vim getComputerConf.sh
3、按i键插入，右键粘贴如下内容：
#!/bin/sh
echo "I will show computer Infomation there"
echo "====================CPU========================"
grep "model name" /proc/cpuinfo
echo ""
echo "================Memory Size===================="
grep MemTotal /proc/meminfo
echo ""
echo "=================32/64Bit======================="
getconf LONG_BIT
echo ""
echo "===============Linux version===================="
echo ""
echo "=================Linux Core====================="
uname -r
echo ""
echo "============HardDisk And Partition=============="
df -h
echo ""
echo "=====================IP=========================="
ifconfig
echo "gateWay"
cat /etc/sysconfig/network
echo "DNS"
cat /etc/resolv.conf
echo ""
echo "=====================Host=========================="
hostname
echo ""
4、esc返回命令模式，输入：wq保存退出
5、当前目录下： sh getComputerConf.sh
6、查看文件大小：du -sh
