How was your input text file formatted?

Hi.

The file was create as: servicoa,servicob,servicoc

and is a text file.

Hi,

Try it this way:

(Get-Content .\serviceList.txt ) -split ',' | ForEach {

    Start-Service -Name $_

}

same error

same error

Not possible. You're using the actual service name, not the display name, correct?

I am, the service started more with error.

example: my text file conatin: WinRM,Spooler,Themes

My script:

 Clear-Host

$serviceList=gc servicos.txt

foreach ($service in $serviceList)

{

$service=$service-split(',')

$first=$service[0]

$second=$service[1]

$third=$service[2]

echo $first

Get-Service -InputObject $first | Start-Service

echo $second

Get-Service -InputObject $second | Start-Service

echo $third

Get-Service -InputObject $third | Start-Service

Get-Service

} 

your script:

 (Get-Content .\servicos.txt ) -split ',' | ForEach {

    Start-Service -Name $_

} 

the error:

 Start-Service : Cannot bind argument to parameter 'Name' because it is an empty string.

At line:4 char:25

+     Start-Service -Name $_

+                         ~~

    + CategoryInfo          : InvalidData: (:) [Start-Service], ParameterBindingValidationException

    + FullyQualifiedErrorId : ParameterArgumentValidationErrorEmptyStringNotAllowed,Microsoft.PowerShell.Commands.StartServiceCo 

   mmand

What's the output of this:

(Get-Content .\servicos.txt  ) -split ',' | ForEach {

    Write-Host "Processing $_"

}

 PS C:\Users\rogerioaguiarpacheco> (Get-Content .\servicos.txt  ) -split ',' | ForEach {

    Write-Host "Processing $_"

}

Processing WinRM

Processing Spooler

Processing Themes

Processing

See those blanks? That's going to be a problem.

Do you have extra commas in the file?

No. I have one comma on file end.

ex: WinRM,Spooler,Themes,

No. I have one comma on file end.

ex: WinRM,Spooler,Themes,

Remove the trailing comma or do something like this:

(Get-Content .\servicos.txt) -split ',' | ForEach {

    If ($_ -ne '') {

        Write-Host "Processing $_"

    }

}

If that gives you the correct output, replace the Write-Host line with the Start-Service -Name $_ line from before.

No. I have one comma on file end.

ex: WinRM,Spooler,Themes,

Indeed that's causing the issue

I can reproduce the issue if my text file is like below

servicoa,servicob, servicoc
BITS,BITS,

Remove the comma at last - it will solve the

Sucess! within the txt had blanks. Removed excluding this spaces.

Thanks for help. :)

I tried to restart/stop/start services on target servers, for example:

$s="RasMan"
$comp = "dc1","sfile"

cls
#restart with error
Invoke-Command {restart-service $s passthru -Force} comp $compCannot bind argument to parameter 'Name' because it is null.
    + CategoryInfo          : InvalidData: (:) [Restart-Service], ParameterBindingValidationException
    + FullyQualifiedErrorId : ParameterArgumentValidationErrorNullNotAllowed,Microsoft.PowerShell.Commands.RestartServiceCommand
