Mastering Windows PowerShell Scripting - Third Edition

Syntax

The syntax section lists each of the possible combinations of parameters a command will accept; each of these is known as a parameter set.

A command that has more than one parameter set is displayed as follows:

SYNTAX    Get-Process [[-Name] <String[]>] [-ComputerName <String[]>]     [-FileVersionInfo] [-Module] [<CommonParameters>]    Get-Process [-ComputerName [<String[]>]] [-FileVersionInfo]    [-Module] -InputObject <Process[]> [<CommonParameters>]

The syntax elements written in square brackets are optional; for example, syntax help for Get-Process shows that all of its parameters are optional, as shown in the following code:

SYNTAX Get-Process [[-Name] <String[]>] [-ComputerName <String[]>] [-FileVersionInfo] [-Module] [<CommonParameters>] ...
