标签:linux   dmidecode   硬件   设备信息   型号   

Dmidecode 用来查看设备硬件信息,包括设备型号、BIOS、系统、主板、处理器、内存、缓存详细信息等等。

常用参数:

# dmidecode -h

Usage: dmidecode [OPTIONS]

Options are:

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

                       从设备文件中读取信息,输出文件内容与不加参数相同

 -h,--help             Display this help textand exit

                       显示帮助信息

 -q,--quiet            Less verbose output

                       简化信息输出

 -s,--string KEYWORD   Only display the valueof the given DMI string

     只显示指定DMI字符串的信息(DMIDesktopManagement Interface, 就是帮助      收集电脑系统信息的管理系统)

 -t,--type TYPE        Only display theentries of given type

                       只显示指定类型的条目

 -u,--dump             Do not decode theentries

                       显示不解码的条目

  --dump-bin FILE      Dump the DMIdata to a binary file

  --from-dump FILE     Read the DMIdata from a binary file

 -V,--version          Display the version andexit

                       显示版本信息

示例:

# dmidecode   将会输出所有硬件及系统信息

# dmidecode -d /dev/mem       同上

# dmidecode –q        简化输出信息

有木有很强大的赶脚,我使用该命令的背景是需要统计生产环境服务器硬件信息,因服务器托管在机房,即不想来回跑机房,又不想翻阅当初采购清单,故通过查阅资料了解了这个dmidecode强大的命令。

再分享一个统计硬件设备信息的脚本
