今天我们领导叫我看下服务器的cpu型号,和主板型号,我当时就纳闷了,cpu型号可以看,主板怎么看呀！只好google了,发现一很给力的命令dmidecode 我大致看了一下man手册,我把我用到的部分贴出来 -t, --type TYPE Only display the entries of type TYPE. TYPE can be either a DMI type number, or a comma-separated list of type numbers, or a keyword from the fol- lowing list: bios, system, baseboard, chassis, processor, memory, cache, connector, slot. Refer to the DMI TYPES section below for details. If this option is used more than once, the set of displayed entries will be the union of all the given types. If TYPE is not provided or not valid, a list of all valid keywords is printed and dmidecode exits with an error. Additionally, type 126 is used for disabled entries and type 127 is an end-of-table marker. Types 128 to 255 are for OEM-specific data. dmidecode will display these entries by default, but it can only decode them when the vendors have contributed documentation or code for them. Keywords can be used instead of type numbers with --type. Each keyword is equivalent to a list of type numbers: Keyword Types ------------------------------ bios 0, 13 system 1, 12, 15, 23, 32 baseboard 2, 10, 41 chassis 3 processor 4 memory 5, 6, 16, 17 cache 7 connector 8 slot 9 Keywords are matched case-insensitively. The following command lines are equivalent: · dmidecode --type 0 --type 13 · dmidecode --type 0,13 · dmidecode --type bios · dmidecode --type BIOS 其他更详细的信息自己去man吧,下面举例 查看cpu信息 [root@localhost ~]# dmidecode -t 4 # dmidecode 2.10 SMBIOS 2.4 present.
