Invoke-PSFCommand
SYNOPSIS
An Invoke-Command wrapper with integrated session management.
SYNTAX
Invoke-PSFCommand [[-ComputerName] <ComputerParameter[]>] [-ScriptBlock] <ScriptBlock>
[[-ArgumentList] <Object[]>] [[-Credential] <PSCredential>] [-HideComputerName] [[-ThrottleLimit] <Int32>]
[<CommonParameters>]
DESCRIPTION
This wrapper command around Invoke-Command allows conveniently calling remote calls.
- It uses the PSFComputer parameter class, and is thus a lot more flexible in accepted input
- It automatically reuses sessions specified for input
- It automatically establishes new sessions, tracks usage and retires sessions that have timed out.
Using this command, it is no longer necessary to first establish a connection and then manually handle the session object. Just point the command at the computer and it will remember. It also reuses sessions across multiple commands that call it.
Note: Special connection conditions (like a custom application name, alternative authentication schemes, etc.) are not supported and require using New-PSSession to establish the connection. Once that session has been established, the session object can be used with this command and will be used for command invocation.
EXAMPLES
EXAMPLE 1
Invoke-PSFCommand -ScriptBlock $ScriptBlock
Runs the $scriptblock against the local computer.
EXAMPLE 2
Invoke-PSFCommand -ScriptBlock $ScriptBlock (Get-ADComputer -Filter "name -like 'srv-db*'")
Runs the $scriptblock against all computers in AD with a name that starts with “srv-db”.
PARAMETERS
-ComputerName
The computer(s) to invoke the command on. Accepts all kinds of things that legally point at a computer, including DNS names, ADComputer objects, IP Addresses, SQL Server connection strings, CimSessions or PowerShell Sessions. It will reuse PSSession objects if specified (and not include them in its session management).
