how to pass parameters to Powershell script and run it on a remote computer

Question

I am trying to pass 2 parameters to a PS script which will patch the SQL Server on a remote machine. Here is the code i used :

$Patcher = "\\remoteShareLocation\SQLpatcher.ps1"
$ver = "SQL2012"
$inst = "NEWINST"

Invoke-Command -ComputerName RMTMACHINE -credential dmn\usrname -ScriptBlock {$Patcher $ver $inst}

This asks for credentials but doesn't run and show any output also. Anything wrong with syntax ? Any alternate cmdlet please ?

Answer 1

if you have powershell V3 or higher you can use the using prefix to "transmit" the local vars to remote host :

Invoke-Command -ComputerName RMTMACHINE -credential $cred -ScriptBlock {$using:Patcher $using:ver $using:inst}

for olders versions look at the -argumentlist parameter of invoke-command

Answer 2

Try

$cred = Get-Credential
Invoke-Command -ComputerName RMTMACHINE -credential $cred -ScriptBlock {$Patcher $ver $inst}

or create a credential object like this:

$username = "username"
$password = "password" | ConvertTo-SecureString -asPlainText -Force
$cred = New-Object System.Management.Automation.PSCredential($username,$password)

You'll need to pass a credential object instead of Domain\\username.

And to run a script file remotely please have a look at https://stackoverflow.com/a/10446318/4550393
