Any ideas what I did wrong here? I copied this script from a tutorial and get this error....

PS C:\Windows\system32> Get-Service | Where-Object ($_.status -eq "running")

Where-Object : Cannot bind parameter 'FilterScript'. Cannot convert value "False" to type "System.Management.Automation
.ScriptBlock". Error: "Invalid cast from 'System.Boolean' to 'System.Management.Automation.ScriptBlock'."
At line:1 char:27
+ Get-Service | Where-Object <<<<  ($_.status -eq "running")
    + CategoryInfo          : InvalidArgument: (:) [Where-Object], ParameterBindingException
    + FullyQualifiedErrorId : CannotConvertArgumentNoMessage,Microsoft.PowerShell.Commands.WhereObjectCommand

Try using {} instead of parentheses around your argument.


Take careful note of the syntax. To begin, the where clause is enclosed within curly braces; in addition, the $_ notation is used to represent the default object (that is, the object being transferred across the pipeline).

Perfect Thanks Holo! –  Campo Jun 16 '10 at 16:01

You need to use { instead of (

Get-Service | Where-Object {$_.status -eq "running"}
