There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "As seen while looking at syntax in Get-Help, commands accept a mixture of parameters."

A block of code is set as follows:

Get-Command -CommandType Cmdlet, Function | Where-Object
{
$metadata = New-Object
System.Management.Automation.CommandMetadata($_)
$metadata.ConfirmImpact -eq 'High'
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

Get-Command -CommandType Cmdlet, Function | Where-Object
{
$metadata = New-Object
System.Management.Automation.CommandMetadata($_)
$metadata.ConfirmImpact -eq 'High'
}

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

 PS> Get-Help Out-Null 

Bold: Indicates a new term, an important word, or words that you see onscreen. Here is an example: "Extensible Markup Language (XML) is a plain text format that's used to store structured data."
