Linux命令筆記之dmidecode用法

標籤：linux   dmidecode   硬體   裝置資訊   型號   

Dmidecode 用來查看裝置硬體資訊，包括裝置型號、BIOS、系統、主板、處理器、記憶體、緩衝詳細資料等等。

常用參數：

# dmidecode -h

Usage: dmidecode [OPTIONS]

Options are:

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

                       從裝置檔案中讀取資訊，輸出檔案內容與不加參數相同

 -h,--help             Display this help textand exit

                       顯示協助資訊

 -q,--quiet            Less verbose output

                       簡化資訊輸出

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

     只顯示指定DMI字串的資訊（DMI即DesktopManagement Interface, 就是協助      收集電腦系統資訊的管理系統）

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

                       只顯示指定類型的條目

 -u,--dump             Do not decode theentries

                       顯示不解碼的條目

  --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

                       顯示版本資訊

樣本：

# dmidecode   將會輸出所有硬體及系統資訊

# dmidecode -d /dev/mem       同上

# dmidecode –q        簡化輸出資訊

有木有很強大的趕腳，我使用該命令的背景是需要統計生產環境伺服器硬體資訊，因伺服器託管在機房，即不想來回跑機房，又不想翻閱當初採購清單，故通過查閱資料瞭解了這個dmidecode強大的命令。

感謝http://www.ibm.com/developerworks/cn/linux/l-10sysadtips/

再分享一個統計硬體裝置資訊的指令碼
