How do I pass a local variable to a remote `Invoke-Command`? [duplicate]

by

In PowerShell 4 (3+ actually) the easiest way is to use the Using scope modifier:

Invoke-Command -ComputerName winserver -ScriptBlock { 
    Get-FileHash E:\test\$Using:dest.zip -Algorithm SHA1 
}

For a solution that works with all versions:

Invoke-Command -ComputerName winserver -ScriptBlock {
    param($myDest)

    Get-FileHash E:\test\$myDest.zip -Algorithm SHA1 
} -ArgumentList $dest
