- Hit in the top pane (labeled Untitled1.ps1), and type the following text.

Note: The command does not execute after this, but it starts a line 2 instead.
- To run the script, click the green button, or press F5. In this part, you can see the result displayed in the middle pane. In the case that it finds an error, a red text will appear. Find these characters : <<<< if you see an error which refers to a specific string of text that caused this problem.

Set-Location C:\Scripts.
- Run the script with the command below (it will fail):
LogInfo.ps1

.\LogInfo.ps1
How to Change a Scrip Using a ForEach Loop
- Select File → New to make a blank area to work with a new script.
- Hit the following text or press F5 to execute it.
get-service | select-object name, status
This list provides all the services on the system by name and their current status.
- The following command will store the result in a collection with the name of $colService.
Note: Notice that you don’t have to retype the entire command, but instead you just add $colService = to the beginning of the line:
$colService = Get-service | select-object
name, status
- To loop through the collection, add a ForEach loop. The task of loop is to check each service stored in the collection and then use the Write-Host cmdlet to display the only services with a status equal to running.
ForEach ($item in $colService) {
If ($item.status -eq “running”)
{write-host $item.name}
}
- You can use the same method to list all the services that are stopped. Therefore you need to change running to stop in the script.
- There is more than one way to get what you need. The following one-liner can be used to get a list of running services as an example:
Get-Service | Select name, status | where {$_.status -eq “running”}
