linux下查看硬件信息的指令，除了我们常见的比如/proc/cpuinfo,/proc/meminfo等，还有一个指令给大家介绍怎么查看硬件信息--dmidecode,希望对大家有点用处。dmidecode是读取DMI的信息显示给大家的。Dmidecode的输出是若干DMI(Desktop Management Interface)表的记录[root@mail proc]# dmidecode --help

Usage: dmidecode [OPTIONS]

Options are:

-d, --dev-mem FILE     Read memory from device FILE (default: /dev/mem)

-h, --help             Display this help text and exit

-q, --quiet            Less verbose output

-s, --string KEYWORD   Only display the value of the given DMI string

-t, --type        Only display the entries of given type

-u, --dump             Do not decode the entries

-V, --version          Display the version and exit以上是它的帮助信息，最有用的当然是参数-t了，它后面可跟的参数有：0 BIOS
