您可以在這裡 深入了解這些新方法about_arrays使用ForEach-Object -Parallel:ForEach-Object -Parallel 在新Runspace 中執行每個腳本區塊。 新的 Runspace 會建立比使用循序處理執行的 ForEach-Object 額外負荷要高得多。 相較於腳本區塊執行的工作,使用平行執行的額外負荷很小,請務必使...
Starting in Windows PowerShell 3.0, there are two different ways to construct a Where-Object command.Script block. You can use a script block to specify the property name, a comparison operator, and a property value. Where-Object returns all objects for which the script block statement is ...
In this tutorial, you’ve learned dabs of how to compare objects with PowerShell in many ways, from file contents to users in AD groups. You’ve realized that theCompare-Objectcmdlet is a quick solution to comparing files, services, processes, and so on. You’ve gained the basic knowledge...

This construct is similar in operation to the ForEach-Object cmdlet. It differs only in its syntax. The purpose of ForEach is to take an array (or collection, which in Windows PowerShell is the same as an array) and enumerate the objects in the array so you can work with one at a ...
built-in Compare-Object cmdlet. This version also works with arrays, arrays of PSCustomObjects and custom classes it iterates over nested objects and properties to compare their values and also support compact output. See description and paramenter help for more. Compares two sets of objects....
If you need to keep the curly braces ({}) in the formatted string, you can escape them by doubling the curly braces. PowerShell "{0} vs. {{0}}"-f'foo' Output foo vs. {0} Index operator[ ] Selects objects from indexed collections, such as arrays and hash tables. Array indexes ...
And one facet of this education is to compare and contrast the two languages, on simple tasks as well as on more-complicated chores.For example, consider the process by which you assign multi-line string values to a variable. In VBScript this is a somewhat less-than intuitive task; that’...
The ForEach-Object cmdlet performs an operation on each item in a collection of input objects. The input objects can be piped to the cmdlet or specified using the InputObject parameter. Starting in Windows PowerShell 3.0, there are two different ways to
