Invoke-Command

Short description
Runs commands on local and remote computers.

Syntax


Description
The Invoke-Command cmdlet runs commands on a local or remote computer and returns all output from the commands, 
including errors. With a single Invoke-Command command, you can run commands on multiple computers.


To run a single command on a remote computer, use the ComputerName parameter. To run a series of related commands that 
share data, use the New-PSSession cmdlet to create a PSSession (a persistent connection) on the remote computer, and 
then use the Session parameter of Invoke-Command to run the command in the PSSession. To run a command in a 
disconnected session, use the InDisconnectedSession parameter. To run a command in a background job, use the AsJob 
parameter.


You can also use Invoke-Command on a local computer to evaluate or run a string in a script block as a command. 
Windows PowerShell converts the script block to a command and runs the command immediately in the current scope, 
instead of just echoing the string at the command line.


To start an interactive session with a remote computer, use the Enter-PSSession cmdlet. To establish a persistent 
connection to a remote computer, use the New-PSSession cmdlet.
