常用用法

[root@localhost ~]$ dmidecode                          # 打印所有硬件信息
[root@localhost ~]$ dmidecode -q                       # 打印所有硬件信息，比较简洁
[root@localhost ~]$ dmidecode | grep 'Product Name'    # 以过滤的方式来查看指定的硬件信息
[root@localhost ~]$ dmidecode --type bios              # 查看BIOS相关的硬件信息
[root@localhost ~]$ dmidecode --type system            # 查看系统相关的硬件信息
[root@localhost ~]$ dmidecode --type baseboard         # 查看主板相关的硬件信息
[root@localhost ~]$ dmidecode --type chassis           # 查看机箱相关的硬件信息
[root@localhost ~]$ dmidecode --type processor         # 查看处理器相关的硬件信息
[root@localhost ~]$ dmidecode --type memory            # 查看内存相关的硬件信息
