PowershellでのWMIツールの使用例
WMIは強力なテクノロジーです.単純にWMIクラス名を指定するだけでクラスのすべてのインスタンスを返すことができます.
PS> Get-WmiObject -Class Win32_BIOS
SMBIOSBIOSVersion : 76CN27WW
Manufacturer : LENOVO
Name : 76CN27WW
SerialNumber : 1006250300406
Version : LENOVO - 1
どのような種類があるかどうやって知っていますか?ここには検索ツールがあります.
function Find-WMIClass
{
param
(
[Parameter(Mandatory=$true)]
$SearchTerm = 'Resolution'
)
Get-WmiObject -Class * -List |
Where-Object { $_.Properties.Count -ge 3 } |
Where-Object { $_.Name -notlike 'Win32_Perf*' } |
Where-Object {
$ListOfNames = $_.Properties | Select-Object -ExpandProperty Name
($ListOfNames -like "*$SearchTerm*") -ne $null
} |
Sort-Object -Property Name
}
検索条件を設定すると、指定した属性名を含むクラスが検索されます(ワイルドカードで検索範囲を拡大することもできます).
「resolution」の末尾を含むすべてのWMIクラスを次に示します.
PS> Find-WMIClass -SearchTerm *resolution
