To support pipelining, the receiving cmdlet must have a parameter that accepts pipeline input. Use the Get-Help command with the Full or Parameter options to determine which parameters of a cmdlet accept pipeline input. For example, to determine which of the parameters of the Start-Service cmdlet accepts pipeline input, type:.
The help for the Start-Service cmdlet shows that only the InputObject and Name parameters accept pipeline input. When you send objects through the pipeline to Start-Service , PowerShell attempts to associate the objects with the InputObject and Name parameters. ByValue : The parameter accepts values that match the expected. NET type or that can be converted to that type. For example, the Name parameter of Start-Service accepts pipeline input by value.
It can accept string objects or objects that can be converted to strings. ByPropertyName : The parameter accepts input only when the input object has a property of the same name as the parameter.
For example, the Name parameter of Start-Service can accept objects that have a Name property. To list the properties of an object, pipe it to Get-Member. Some parameters can accept objects by both value or property name, making it easier to take input from the pipeline. When you pipe objects from one command to another command, PowerShell attempts to associate the piped objects with a parameter of the receiving cmdlet.
PowerShell's parameter binding component associates the input objects with cmdlet parameters according to the following criteria:. For example, the Start-Service cmdlet has many parameters, but only two of them, Name and InputObject accept pipeline input. The Name parameter takes strings and the InputObject parameter takes service objects. Therefore, you can pipe strings, service objects, and objects with properties that can be converted to string or service objects.
PowerShell manages parameter binding as efficiently as possible. You can't suggest or force the PowerShell to bind to a specific parameter.
The command fails if PowerShell can't bind the piped objects. For more information about troubleshooting binding errors, see Investigating Pipeline Errors later in this article. Piping objects to a command is much like using a parameter of the command to submit the objects. Let's look at a pipeline example. In this example, we use a pipeline to display a table of service objects.
Functionally, this is like using the InputObject parameter of Format-Table to submit the object collection. For example, we can save the collection of services to a variable that is passed using the InputObject parameter.
However, there's an important difference. How do I copy a file in bash? Copy a File cp You can also copy a specific file to a new directory using the command cp followed by the name of the file you want to copy and the name of the directory to where you want to copy the file e.

For the record, the reason it "doesn't seem to support pipelines" is simply because you haven't escaped it, it is piping for instead of ipconfig. Thanks neurolysis, will update my answer to include that.
Well I meant piping to For, like before it. But i'm convinced one can't. But can in the "in" as in Mikel's suggestion. But trying Mikel's line, I did run into a problem with Mikel's line..
