Powershell passing variables to remote script

Paul picture Paul · Oct 23, 2012 · Viewed 9.1k times · Source

I have the following cmd file:-

PowerShell.exe -noexit E:\wwwroot\domains\processes\AddDirectory.ps1 -Param testdomain.co.uk

which goes through to:-

$Session = New-PSSession -ComputerName 192.168.0.25
$script = {
Param($Param1)
set-executionpolicy unrestricted -force

# Set Variables
$domain = $Param1
$sitepath = "e:\domains\" + $domain

# Check for physical path
if (-not (Test-Path -path $sitePath))
{
New-Item -Path $sitepath -type directory 
New-Item -Path $sitepath\wwwroot -type directory 
}
set-executionpolicy restricted -force     
}
Invoke-Command -Session $Session -ScriptBlock $script

But it just runs but does nothing.

If I declare the $domain variable as $domain = 'testdomain.co.uk' it works but it doesn't want to pass through the var from the cmd file. What am I doing wrong? I've tried to put it in the Invoke-Command as -ArgumentsList -$Param1 but that doesn't work either.....

Any ideas greatfully received

Thanks Paul

Update - I've updated my code as per below but getting same issue:-

param($domainName)
$script = {
    Param($Param1)
    set-executionpolicy unrestricted -force
    # Set Variables
    $domain = $Param1
    $sitepath = "e:\domains\" + $domain
    # Check for physical path
    if (-not (Test-Path -path $sitePath))
    {
        New-Item -Path $sitepath -type directory
        New-Item -Path $sitepath\wwwroot -type directory
        New-Item -Path $sitepath\db -type directory
        New-Item -Path $sitepath\stats -type directory
    }
    set-executionpolicy restricted -force
}

$Session = New-PSSession -ComputerName 192.168.0.25

Invoke-Command -Session $Session -ScriptBlock $script -ArgumentList $domainName

You need to use a param block in the script, the argument you pass to the file will be assign to $domainName and you will use it to pass the value to the scriptblock :

PowerShell.exe -noexit E:\wwwroot\domains\processes\AddDirectory.ps1 testdomain.co.uk


# script file

param($domainName)

$script = {
    Param($Param1)

    ...
    $domain = $Param1
    ...   
}

$Session = New-PSSession -ComputerName 192.168.0.25
Invoke-Command -Session $Session -ScriptBlock $script -ArgumentList $domainName
