WMI（windows管理規(guī)范），是Windows 2K/XP管理系統(tǒng)的核心；對于其他的Win32操作系統(tǒng)，WMI是一個有用的插件。WMI以CIMOM為基礎(chǔ)。

CIMOM即公共信息模型對象管理器（Common Information Model Object Manager），是一個描述操作系統(tǒng)構(gòu)成單元的對象數(shù)據(jù)庫，為MMC和腳本程序提供了一個訪問操作系統(tǒng)構(gòu)成單元的公共接口。有了WMI，工具軟件和腳本程序訪問操作系統(tǒng)的不同部分時不需要使用不同的API；相反，操作系統(tǒng)的不同部分都可以插入WMI，如圖所示，工具軟件和腳本程序可以方便地讀寫WMI。

學習目標

• 獲取所有的WMI對象

• WMI類詳細信息顯示

• 使用WMI對計算機信息進行收集

• 使用WQL語句

WMI對象

• WMI對象：WmiObject

• WMI：Windows管理規(guī)范

• WMI將數(shù)據(jù)視為有一個或多個項目的集合中的對象

• 通過WMI可以使用較少的工作量執(zhí)行高級工作

• 獲取WMI對象：Get-WmiObject

• 顯示所有的WMI對象

手動創(chuàng)建的共享type為0，系統(tǒng)默認的共享，type值不為0，所以可以用以下方法過濾出手動創(chuàng)建的共享目錄

1	Get-WmiObject?win32_share?|??{$_.type?-eq?0}

使用WQL語句

使用WQL語句可以用于篩選WMI對象

語法:

1	Get-WmiObject?-Query?"select?[對象]?from?WMI對象??WHERE?條件“

上面的命令可以分解成兩條：

• get-wmiobject -query "WQL語句"?

• WQL= ”select * from Wmi對象 where 條件“

練習：

• 列出本機的WmiObject對象

• 只獲取win32_開頭的對象

• 獲取所有的Win32_Share對象，并用列舉的方式表示

• 查找狀態(tài)為running的win32_service對象
  

• 查找startMode為Auto的win32_service對象

• 查看所有的本地磁盤
  

• 查找每個磁盤的剩余空間

例如： 查看所有由用戶創(chuàng)建的共享目錄

1	Get-WmiObject?-query?"select?*?from?win32_share?where?type=0"

練習1：獲取win32_開頭的對象

1	Get-WmiObject?-list?win32_*

練習2：查找狀態(tài)為running的win32_service對象

1	Get-WmiObject?-query?"select?*?from?win32_service?where?state='running'"

以列表形式顯示：

很多WMI對象可以使用cmdlet獲取，例如：

• Get-WmiObject win32_service ?== Get-Service

• Get-WmiObject win32_Process ?== Get-Process
