Linux dmidecode 命令

dmidecode 用于获取主机的硬件信息，通常是在不打开计算机机箱的情况下使用该命令来查找硬件详细信息，常见用法如下：

[root@localhost ~]$ yum install -y dmidecode

[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

[root@localhost ~]$ dmidecode -q
