Can I call my function from a script in Invoke-Command?

Question

PowerShell

Those. there is a ps1 script, it has a TestFunc function and a call to this function

Invoke-Command -ComputerName 192.168.0.1 -ScriptBlock {(TestFunc "test")}

Writes
The name 'TestFunc' is not recognized as the name of a cmdlet, function, script file, or executable program.

Or should the function be placed in a separate script and called as -FilePath?

Answer 1

here, it seems, in detail:
duffney.io/RunLocalFunctionsRemotely

function MyFunction ()
{
    Write-Host 'Hello, World!'
}

Invoke-Command -ComputerName DC1 -ScriptBlock ${Function:MyFunction}

Answer 2

Or here

The FilePath parameter specifies a script that is located on the local computer. The script runs on the remote computer and the results are returned to the local computer.
