常用dmidecode命令

Dmicode这款软件可以在linux操作系统中收集硬件信息,该软件遵循SMBIOS标准,其输出的信息包括系统制造商、型号、序列号、BIOS版本、CPU、内存、PCI、及I/O接口等,该软件非常强大也非常实用。

SMBIOS(System Management BIOS)和DMI(Desktop Management Interface)都是由DMTF(Desktop Management Task Force)起草的开放性的技术标准,DMTF组织于1992年成立,DMTF工作组致力于分布式IT系统的有效管理,通过聚合众多IT厂商一起来进行管理系统的开发、效用及改进等标准化工作。其官方网站为:http://www.dmtf.org/

以下为常用的dmidecode命令:
1、精简显示dmi信息
#dmidecode -q
2、查看设备的型号
dmidecode | grep ‘Product Name’
3、查看设备的序列号
dmidecode |grep ‘Serial Number’
4、查看系统的序列号
dmidecode -s system-serial-number
5、查看内存槽位及内存大小
dmidecode|grep P A5 “Memory\s+Device”|grep Size|grep v Range
6、查看支持的最大内存数
dmidecode|grep P ‘Maximum\s+Capacity’
