How can I change the PowerShell prompt to show just the parent directory and current directory?

Question

I would like to shorten my PowerShell prompt so that it just shows the parent directory and the current directory. For example, if the pwd is

C:\\Users\\ndun

Try this (too long for a comment):

function prompt 
{
    $aux=$executionContext.SessionState.Path.CurrentFileSystemLocation.Path -Split '\\|\/'
    if ( $aux.Count -le 3 ) {
        Write-Host ("PS $($aux -join '\')>") -NoNewline # -ForegroundColor Cyan
    } else {
        Write-Host ("PS $($aux[0])\..\$($aux[-2..-1] -join '\')>") -NoNewline # -ForegroundColor Cyan
    }
    return " "
}
