There are two ways to use the foreach loop parallelly in PowerShell.Using Foreach-Object -Parallel command (Supports in PowerShell 7.0 or above)Using Foreach -Parallel in Workflow (Supports PowerShell 5.1 or below)Suppose we have Servers.txt and which contains 10 Servers. When we use the Parallel for loop, it isn’t guaranteed which server loop will pick first as shown below with two examples.Using Foreach-Object-Parallel command. (not Foreach -Parallel)This Foreach-Object -Parallel command feature is newly added to the PowerShell version 7.0 or above.Example$servers = Get-Content C:\Temp\Servers.txt $servers | foreach-Object -parallel{ Write-output "Working on $_" }OutputPS C:\> C:\Temp\Test1.ps1 Working on IndiaServer003 Working on IndiaServer002 Working on IndiaServer001 Working on ...

To validate the IP address using PowerShell, we can use several methods as shown below.Using RegEx method.Using Typecasting method.Using TypeCasting method.In this method, we are using System.Net method class IPAddress to validate the IP address.[ipaddress]$IP = "192.168.0.1"The above one is valid. Let’s check what $IP stores in.PS C:\> $IP Address : 16820416 AddressFamily : InterNetwork ScopeId : IsIPv6Multicast : False IsIPv6LinkLocal : False IsIPv6SiteLocal : False IsIPv6Teredo : False IsIPv4MappedToIPv6 : False IPAddressToString : 192.168.0.1The above one is Ipv4 and this method also works for IPv6. See the example below.PS C:\> [ipaddress]"2001:0db8:85a3:0000:0000:8a2e:0370:7334" Address : AddressFamily : InterNetworkV6 ScopeId ... Read More

To check if the PowerShell string contains a specific word, we can use the string method Contains(). For example, ExamplePS C:\> $str = 'TestNZ01LT' PS C:\> $str.Contains('NZ') TrueNow the funny thing is, even if the PowerShell is case-Insensitive, the above command is not. We need to provide the exact substring. For example, the below output will be false.ExamplePS C:\> $str.Contains('Nz') FalseTo overcome this problem, we can either provide the same search name in the method or we need to use the lowercase or uppercase method if you don’t want the search case-sensitive.PS C:\> $str = 'TestNZ01LT' PS C:\> ($str.ToLower()).Contains(('Nz').ToLower()) True ...

When we write Invoke-Command in PowerShell, sometimes we get the RunSpaceID property in PowerShell. This is because we use Select-Object (alias: Select) command inside the scriptblock. For example,ExampleInvoke-Command -ComputerName LabMachine2k12 -ScriptBlock{Get-Process PowerShell | Select Name, CPU, WorkingSet}OutputName : powershell CPU : 9.1572587 WorkingSet : 127700992 PSComputerName : LabMachine2k12 RunspaceId : c690f205-06d4-4cc4-be29-5302725eadf1To avoid getting the RunSpaceID property in the output, use the Select command output the scriptblock. For example,ExampleInvoke-Command -ComputerName LabMachine2k12 -ScriptBlock{Get-Process PowerShell} | Select Name, CPU, WorkingSetOutputName CPU WorkingSet ---- --- ---------- powershell 9.1572587 127700992

When we are working with Invoke-Command, we get the PSComputerName extra field in the output table. You can remove it by using -HideComputerName parameter. For example, the Below command gives the output with the PSComputerName property.ExampleInvoke-Command -ComputerName LabMachine2k12 -ScriptBlock{Get-Service Winrm} | ft -AutoSizeOutputStatus Name DisplayName PSComputerName ------ ---- ----------- -------------- Running Winrm Windows Remote Management (WS-Management) LabMachine2k12To hide the PSComputerName property,ExampleInvoke-Command -ComputerName LabMachine2k12 -ScriptBlock{Get-Service Winrm} -HideComputerNameOutputStatus Name DisplayName ------ ---- ----------- Running Winrm Windows Remote Management (WS-Management)

To find the device driver version using PowerShell, we need to use the class win32_PnpSignedDriver of the WMI object. For example, ExampleGet-WmiObject win32_PnpSignedDriverOr if you are using PowerShell core (PowerShell 6.0 or later), you can use the CIM Instance command. For example, Get-CimInstance win32_PnpSignedDriverTo filter out the Drivers against their versions, use the below command to filter.Examplegwmi win32_PnpSignedDriver | Select Description, DriverVersionOutputACPI x64-based PC 6.2.9200.16384 UMBus Root Bus Enumerator 6.2.9200.16384 WAN Miniport (IPv6) 6.2.9200.16384 Composite Bus Enumerator ...
