Getting Local Variables into Remote Sessions

2 Replies

There are at least three ways to get your local variables into your remote sessions. I’ve written these in preferential order beginning with the best option. Don’t forget to read about_Remote_Variables (Get-Help -Name about_Remote_Variables) to learn more, and see more examples.

$Word1 = 'PowerShell'
$Word2 = 'on'
$Computer = 'Server1'

# Using Scope Modifier
# (1st Option -- works in PowerShell 3.0 and up)
Invoke-Command -ComputerName $Computer -ScriptBlock {
    Write-Verbose -Message "$Using:Word1 $Using:Word2 $env:COMPUTERNAME (Using Scope Modifer)" -Verbose
}
VERBOSE: PowerShell on Server1 (Using Scope Modifier)


# Param
# (2nd Option -- works in PowerShell 2.0 and up)
Invoke-Command -ComputerName $Computer -ScriptBlock {
    Param($Word1InParam,$Word2InParam)
    Write-Verbose -Message "$Word1InParam $Word2InParam $env:COMPUTERNAME (Param)" -Verbose
} -ArgumentList $Word1, $Word2
VERBOSE: PowerShell on Server1 (Param)


# Args
# (3rd Option -- works in PowerShell 2.0 and up)
Invoke-Command -ComputerName $Computer -ScriptBlock {
    Write-Verbose -Message "$($args[0]) $($args[1]) $env:COMPUTERNAME (Args)" -Verbose
} -ArgumentList $Word1, $Word2
VERBOSE: PowerShell on Server1 (Args)
