Why PS didn't saved informations in these txt files? - powershell

Question

I didn't got any errors and powershell made these files, but they are empty. What did i wrong?
$Services = Get-Service
Foreach ($Proces in $Services) {
If($Proces.status -eq "running") { Out-File $Proces >> "C:\proces.txt"}
If($Proces.status -eq "stopped") { Out-File $Proces >> "C:\proces2.txt"}
}

Answer 1

>> is the append redirect operator, which is basically the same as Out-File -Append. So it is like calling Out-File twice.
With the command Out-File $Proces >> "C:\proces.txt" you pass in no input object to Out-File. So you write a blank file to $Proces. Then take the output of that command (nothing) and write that to C:\proces.txt, which creates the second blank file.
So you will want to decide on using Out-File -Append or >>
Here is your code using just Out-File:
$Services = Get-Service
Foreach ($Service in $Services) {
If ($Service.Status -eq "Running") { Out-File -InputObject $Service -Path "C:\proces.txt" -Append}
If ($Service.Status -eq "Stopped") { Out-File -InputObject $Service -Path "C:\proces2.txt" -Append }
}
Here is your code using just >>:
$Services = Get-Service
Foreach ($Service in $Services) {
If ($Service.Status -eq "Running") { $Service >> "C:\proces.txt" }
If ($Service.Status -eq "Stopped") { $Service >> "C:\proces2.txt" }
}
There are many other ways to do what you are attempting
Here is a way using the Where-Object cmdlet rather than a loop/conditional
$Services = Get-Service
$Services | Where-Object {$_.Status -eq "Running"} | Out-File "C:\proces.txt" -Append
$Services | Where-Object {$_.Status -eq "Stopped"} | Out-File "C:\proces2.txt" -Append
Here is a way using the .where() method using split
$Running,$Stopped = (Get-Service).Where({$_.Status -eq 'Running'},'Split')
$Running | Out-File "C:\proces.txt" -Append
$Stopped | Out-File "C:\proces2.txt" -Append
