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)

# 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
