在FILTER 参数中使用 WQL 运算符 WQL 运算符还可以用在 或Get-WmiObject cmdlet 的 Get-CimInstance 参数的值中,以及这些 cmdlet 的 Query 参数的值中。 例如,以下命令获取过去五个进程 ProcessId 值大于 1004 的 Name 和ProcessId 属性。 该命令使用 Filter 参数来指定 ProcessId 条件。 PowerShell 复制 $get...
filter關鍵詞是用來建立在管線中每個物件上執行的函式類型。 篩選條件類似於函式,其中包含區塊中的所有process語句。 函式也可以像 Cmdlet 一樣運作。 您可以建立與 Cmdlet 一樣運作的函式,而不需使用C#程序設計。 如需詳細資訊,請參閱about_Functions_Advanced。
当表达式中的左侧值是集合时,运算符将返回与表达式的右侧值匹配的集合的元素。 即使它们是集合,右侧值也始终被视为单一实例。 比较运算符无法有效地将集合与集合进行比较。 如果集合中没有匹配项,比较运算符将返回空数组。 例如: PowerShell 复制 $a = (1, 2) -eq 3 $a.GetType().Name $a.Count 输出...

Use logical operators (-and,-or,-xor,-not,!) to connect conditional statements into a single complex conditional. For example, you can use a logical-andoperator to create an object filter with two different conditions. For more information, seeabout_Logical_Operators. ...
We often encounter support cases where our customers leave the query execution timeout value at its default. In certain situations, we may find that when...
That’s easy: you can use Get-ChildItem to return a collection of all the files in the folder, filter out everything that didn’t have a .PS1 file extension, and then check to see if the number of items in the collection is greater than 0. Good point; maybe that isn’t as easy ...
