Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "Use Get-ChildItem to list all of the environment variables:"

A block of code is set as follows:

function Get-IPConfig { 
    [System.Net.NetworkInformation.NetworkInterface]::GetAllNetworkInterfaces() | ForEach-Object { 
        $ipProperties = $_.GetIPProperties() 
             
        $addresses = $ipProperties.UnicastAddresses | 
            Where-Object { 
                $_.Address.AddressFamily -eq 'InterNetwork' 
            } | ForEach-Object { 
                "$($_.Address) $($_.IPv4Mask)" 
            } 
 
        $gateway = $ipProperties.GatewayAddresses.Address | 
            Where-Object { 
                $_.AddressFamily -eq 'InterNetwork' -and  
                $_ -ne '0.0.0.0' 
            } 
 
        [PSCustomObject]@{ 
            Name      = $_.Name 
            Id        = $_.Id 
            Addresses = $addresses 
            Gateway   = $gateway 
        } 
    } | Where-Object { $_.Addresses } 
} 
Get-IPConfig 

Any command-line input or output is written as follows:

PS> Update-Help -Module DnsClient -Verbose
