远程调用命令-找不到功能/ cmdlet

Question

I've got the following script:

param(
    [string[]]$servers
)

function Write-Info($message) {
}

function Introspect($server) {
    Write-Info "about to do something on server"    
    // other powershell stuff that works
}

Foreach ($server in $servers) {
    Invoke-Command -ComputerName $server -ScriptBlock ${function:Introspect} -ArgumentList $server -credential 'MyUser'
}

That I'm trying to invoke on a remote server like so (from powershell):

.\myscript.ps1 server1,server2,server3

The script is executing, but the issue is I get an error relating to the Write-Info function like so:

The term 'Write-Info' is not recognised as the name of a cmdlet, function, script file, or operable program

The Introspect function works fine if I embed the function inside but I guess it relates to the function not being on the remote server.

How can I solve this please?

Answer 1

Managed to solve this by embedding the 'missing' function inside the working one:

param(
    [string[]]$servers
)

function Introspect($server) {

    function Write-Info($message) {
    }
    Write-Info "about to do something on server"    
    // other powershell stuff that works

}

Foreach ($server in $servers) {
    Invoke-Command -ComputerName $server -ScriptBlock ${function:Introspect} -ArgumentList $server -credential 'MyUser'
}
