Supplying options for cmdlets

One of the useful features of Windows PowerShell is the standardization of the syntax in working with cmdlets. This vastly simplifies the learning of the new shell and language. Table 1-1 lists the common parameters. Keep in mind that some cmdlets cannot implement some of these parameters. However, if these parameters are used, they will be interpreted in the same manner for all cmdlets, because the Windows PowerShell engine itself interprets the parameters.

Table 1-1 Common parameters

Parameter	Meaning
-whatif	Tells the cmdlet to not execute, but to tell you what would happen if the cmdlet were to run.
-confirm	Tells the cmdlet to prompt before executing the command.
-verbose	Instructs the cmdlet to provide a higher level of detail than a cmdlet not using the verbose parameter.
-debug	Instructs the cmdlet to provide debugging information.
-ErrorAction	Instructs the cmdlet to perform a certain action when an error occurs. Allowed actions are continue, stop, silentlyContinue, and inquire.
