Questions tagged [invoke-command]

Invoke-Command is a powershell cmdlet that runs commands on local and remote computers.

Invoke-Command is a powershell cmdlet that runs commands on local and remote computers 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.
