How for loop works in Powershell? Once for loop start it first allocate initial value of variable into memory, this happens once when for loop get started. On the each iteration value of $i will change , along with checking condition(if condition is true or false). An examples below. fo...
In PowerShell, commands are executed sequentially. But sometimes, you may need to repeat a command or a set of commands until a certain condition is met. This is called a loop. Advertisement To define what the conditions are to enter or exit a loop in PowerShell, you need to use compari...
One of PowerShell’s key features is its ability to loop through data collections, enabling you to execute a code block repeatedly. In this tutorial, we will explore three fundamental loop structures in PowerShell:foreach,for, anddoloops. By the end of this tutorial, you will have a solid...
This example is the combination of the last two code examples. It skipped the iteration at number 5 and continued with the subsequent iterations but exited the loop when the number was 9. The break can also be used within the switch and trap in PowerShell. Let’s add a twist to the ab...
Next, let’s look at some practical examples of PowerShell scripting when you can use foreach loops to perform some actions against all objects in a directory. Delete files in a directory that are older than xx days: Get-ChildItem C:\ps\ -Recurse | ...
ForEach PowerShell Examples Let us look at a few examples of how to use the ForEach loop. These are based on real-world use cases showing the concept which you can modify to fit your requirements. Example 1: Creating a File in Each Sub-Folder in a Directory using the ForEach Statement...
In PowerShell 7, the-Parallelparameter was added to theForEach-Objectcmdlet. This allows the pipeline to process multiple objects simultaneously. Processing multiple objects simultaneously can provide better performance than a standardForEachloop. You should consider this if you're ...
In later examples, code is integrated into the For statement. For example, the following For statement continually displays the value of the $i variable until you manually break out of the command by pressing CTRL+C. PowerShell Copy $i = 1 for (;;) { Write-Host $i } You can add...

In PowerShell 7, a new runspace is created for each loop iteration to ensure maximum isolation. This can be a large performance and resource hit if the work you are doing is small compared to creating new runspaces or if there are a lot of iterations performing significant work. As of Pow...
