Linux下查看CPU信息、机器型号等硬件信息命令

编写一个bash脚本：

vim info.sh

#!/bin/bash
    cat /etc/issue
    echo "_________________________________"
    cat /proc/cpuinfo |grep name|cut -f2 -d:|uniq -c
    echo "_________________________________"
    cat /proc/cpuinfo |grep physical|grep -v address|uniq -c
    echo "_________________________________"
    getconf LONG_BIT
    echo "_________________________________"
    #free -mto
    cat /proc/meminfo |grep MemTotal
    echo "_________________________________"
    #出现了2次的SN号就是服务器的SN号
    dmidecode |grep -A16 "Memory Device$"|grep Size|grep -v No
    sleep 3
    echo "_________________________________"
    df -h
    echo "_________________________________"
    dmidecode | egrep "Product Name|Serial Number" |egrep -v "Not|none" 
    echo "_________________________________"
    exit 0

测试机器的硬件信息：  
查看CPU信息（型号）  
\# cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c  
8 Intel(R) Xeon(R) CPU E5410 @ 2.33GHz  
(看到有8个逻辑CPU, 也知道了CPU型号)  
www.2cto.com  
\# cat /proc/cpuinfo | grep physical | uniq -c  
4 physical id : 0  
4 physical id : 1  
(说明实际上是两颗4核的CPU)  
  
\# getconf LONG\_BIT  
32  
(说明当前CPU运行在32bit模式下, 但不代表CPU不支持64bit)  
  
\# cat /proc/cpuinfo | grep flags | grep ' lm ' | wc -l  
8  
(结果大于0, 说明支持64bit计算. lm指long mode, 支持lm则是64bit)  
  
再完整看cpu详细信息, 不过大部分我们都不关心而已.  
\# dmidecode | grep 'Processor Information'  
  
查看内存信息  
\# cat /proc/meminfo  
www.2cto.com  
\# uname -a  
Linux euis1 2.6.9-55.ELsmp \#1 SMP Fri Apr 20 17:03:35 EDT 2007 i686 i686 i386 GNU/Linux  
(查看当前操作系统内核信息)  
  
查看内存插槽几个，以及安了几条内存。  
\#dmidecode |grep -A16 "Memory Device$"  
强悍，size有大小的就是安装内存条了的  
\#dmidecode |grep -A16 "Memory Device$"|grep Size \#\#这样更直观些

\# cat /etc/issue | grep Linux

Red Hat Enterprise Linux AS release 4 (Nahant Update 5)  
(查看当前操作系统发行版信息)  
  
查看机器型号  
\# dmidecode | grep "Product Name"

查看网卡信息

\# dmesg | grep -i eth  
\#dmesg |egrep -i eth

\#查看有几块网卡  
\#lspci |egrep -i eth
